Halo Collar vs. SpotOn Collar

What's the difference?

SpotOn Fence and Halo Collar are both popular GPS dog fence systems that offer an alternative to traditional or Invisible Fences®. So naturally, if you’re doing your research, you are bound to have questions about what makes the two systems different.

Ensuring your pet's safety means getting the facts straight, so we encourage you to research both products. Here are some reviews from neutral third parties who’ve done the heavy lifting of exploring the two products in-depth to provide their honest feedback, as well as links to our nearly 10,000 verified five-star customer reviews.

SpotOn GPS Fence Comparisons and Reviews from Neutral Sources

In this article, we’ll provide our perspective on what makes SpotOn Nova Edition different from Halo Collar 5. Here is a preview of some of the key areas we’ll explore and why we think you can rely on SpotOn:

Superior Tech

SpotOn features a premium, active dual-band, dual-feed antenna with a reception area that's 5x larger than Halo. This ensures stronger GPS signals that filter out interference for superior accuracy—even in challenging environments like dense woods.

Long-term Value & Cost of Ownership

SpotOn offers unlimited fences with no subscription, while Halo limits you to 5 fences on its lowest plan and carries hidden fees. Though SpotOn has a higher upfront cost, Halo is actually more expensive after 2 years.*

  • SpotOn - $1,178 for 2 years
  • Halo Collar - $1,317 for 2 years

*Prices include collar, charger, shipping, tracking, unlimited fences, keep out zones, and a care plan.

Better User Experience

SpotOn provides exceptional flexibility with unlimited customizable fences that overlap and curve around any property shape. You can set multiple keep-out areas and disable alerts indoors at no extra cost.

Unmatched Customer-Centric Protection

SpotOn backs our product with a 5-Star Guarantee: try it for 90 days—if it’s not for you, return it. Enjoy accident forgiveness as part of the 1-year warranty, ensuring your satisfaction.

American Quality and Integrity

SpotOn embodies American quality and integrity through our proud New Hampshire manufacturing and customer service teams.

Two GPS dog collars, SpotOn Nova Edition and Halo Collar.

SpotOn's Superior GPS Accuracy is Backed by Independent Testing

SpotOn was founded by a team that specializes in GPS technology for the military, so best-in-class engineering, components, and technology is an area that we take seriously and don’t cut corners.

In fact, SpotOn was even tested by an independent testing lab and was proven to be the most accurate and reliable system in 2025. Spirent, a globally recognized and leading expert in GNSS testing, performed the head-to-head tests of SpotOn vs. leading GPS fences and found SpotOn consistently demonstrated more accuracy and consistency - up to 9 times greater. You can view the data for additional details, but here are a few highlights:

  • Absolute Accuracy - Only SpotOn works as promised with just 2.3 feet of fence line drift.
  • Consistent Alerts - Only SpotOn issued alerts 100% of the time during lab testing.
  • Pinpoint Precision - Only SpotOn performs just as precisely in the presence of trees, buildings, and other multipath conditions.

GPS Antennas: Why SpotOn is so accurate

SpotOn's Nova Edition offers a new premium GPS antenna. It features a dual-band and dual-feed active antenna. This is different (and better!) than the dual-feed antenna in previous SpotOn collars and works with a dual-feed receiver.

With a reception area that's five times larger than Halo's, the Nova Edition deliver stronger signals and precise tracking—something smaller antennas can’t achieve. 

Size really does matter.  Smaller antennas, or lower-grade ones with passive or single-feed antennas, will degrade the accuracy of the boundary and cause more GPS drift. Our high-fidelity antenna is able to filter out inferior GPS signals affected by trees, buildings, or the horizon, generating fence boundaries that are reliable 100% of the time.

While SpotOn's choice to use premium components drives up the cost of our collars, accuracy and reliability are our top priorities and areas where we don't cut corners. A GPS collar and fence that's less expensive, less accurate, or "almost safe" can leave holes in containment, and that’s never safe enough.

Independent testing found the next-best GPS fence was only 78%. Meaning there are holes in the fence nearly 12% of the time. SpotOn is 100% reliable, delivering a fence with no gaps or holes–ever

SpotOn’s True Location™ Technology Helps Solve for GPS Drift

When we designed SpotOn, we set our standards extremely high, knowing that all GPS products have inherent GPS drift, a natural phenomenon that occurs with any GPS product. To address this limitation, we patented True Location™ technology, which balances GPS drift and automatically adjusts your dog’s location to make their boundaries and position more accurate.

We determined that six feet was the maximum acceptable drift for a GPS fence. SpotOn's previous Omni Edition performed to this spec 96% of the time in lab testing and our new Nova Edition exhibits 40% less drift than Omni. In the 2025 testing, Halo’s maximum drift was recorded at 45 feet.

In addition to the independent lab testing, there are numerous experts in the pet, tech, and DIY spaces that have created their own head-to-head videos to test accuracy. Examples include: The World Animal Foundation, YouTube creator and dog dad Christopher Burress (Simply CB); Joel, Editor at Cozy CratesDIY with James Clinton, and more. 

Professional Dog Trainer, Evan Doggett, who specializes in e-collar training, recently compared Halo Collar versus SpotOn, which helps validate the lab testing results:

SpotOn Alerts and Tones are More Reliable and Consistent

The reliability of the fence’s alerts is also critical. SpotOn’s alerts and warnings are designed to be issued 10 feet and again at 5 feet before the fence line.

Why is this important? Consistent alerts make it easier to train your dog and help them understand and respect the fence's boundaries when unsupervised outdoors. During independent testing, SpotOn issued all three stimuli 100% of the time.

Not only does SpotOn excel in accuracy, but our system also proves to be 99.3% effective at preventing escapes. For the rare cases of a boundary breach, only 0.0066312% of these sessions result in an escape that’s 5 minutes or more (and if you add a tracking plan, you can watch their every move).

Infographic showing how SpotOn issues cues to your dog's collar as they near a virtual fence boundary: an alert tone 10 feet from the boundary, a more urgent warning tone 5 feet from the boundary, and a vibration or optional static correction at the boundary.

SpotOn is SAR Compliant: Safer for Your Pet’s Health

Specific Absorption Rate (SAR) measures the rate at which energy is absorbed by the human body when exposed to a radio frequency (RF) electromagnetic field. It is a critical indicator of the safety levels of various wireless devices, including wearables.

By attaining SAR compliance, SpotOn has minimized your dog's RF exposure and potential health risks. Although regulations for pet wearables regarding SAR are not required, SpotOn’s SAR compliance meets regulations for human use.

SpotOn is the only GPS smart collar that meets this standard, showing that we seek to go above and beyond for the safety of your pet as a company.

SpotOn Works Where Others Don’t: More Accurate in Wooded Areas

SpotOn’s GPS fence technology is built to perform where others can’t, making it highly effective in wooded areas and under dense foliage. Equipped with Forest Mode as a default setting, the collar automatically boosts GPS sensitivity to ensure secure boundaries even when trees, brush, or thick vegetation surround your dog. This advanced feature adjusts in real-time, keeping virtual fences intact regardless of challenging terrain. Unlike traditional GPS devices that can struggle with interference in natural environments, SpotOn’s innovative design allows your dog to roam securely within an accurate perimeter.

SpotOn’s exceptional accuracy in wooded areas is driven by top-tier GPS components and unique technology. The collar’s high-quality dual-feed, noise-resistant GPS antenna can access 151 satellites from six distinct constellations: GPS, GLONASS, Beidou, Galileo, NavIC, and QZSS. Connecting to up to 35 satellites at any one time, your SpotOn Fence will be in constant communication with these satellite systems, which means it can more accurately interpret your dog’s location.

SpotOn vs. Halo Price Comparison

Premium Features, Lower Long-Term Costs with SpotOn

It’s no secret that SpotOn is more expensive than Halo. A proud American brand, SpotOn is designed, assembled, and shipped from Manchester, NH. Our entire manufacturing team and customer service staff are based in-house and we pay our employees a fair living wage.

But beyond that, our components are of higher quality, and you simply get more with SpotOn.

  • No extra fees for features powered by a GPS connection. SpotOn’s unlimited fences, Keep Out Zones, Home Zones, and Off-grid Mode will all work right out of the box. With Halo 5, you must upgrade to a Gold Plan for unlimited fences.
  • Subscriptions are always your choice. Subscriptions are extremely valuable, but if you live in an area with little to no cellular coverage, you will run into issues, no matter which GPS dog fence you choose. SpotOn does not force customers to pay for a subscription, while Halo does. Our monthly subscriptions start at $7.49 and unlock cellular-powered features like tracking, activity maps, escape reports, and more.
  • Every SpotOn collar comes with a free 5-star guarantee to protect your investment. It entitles you to a 90-day return window (with no restocking fees), a 1-year warranty with a free one-time replacement if your collar is lost or damaged, a free session with a certified dog trainer, and unlimited customer support. Everyone gets the same top-notch customer service with SpotOn, unlike Halo, which limits top-tier support only to those who pay for their priciest pack membership plan.
  • All customers are eligible to beta tests for new features and a 25% discount on accessories.

SpotOn’s philosophy is that our customers should get everything they need to get started when they invest in a collar. Furthermore, GPS-powered features should be free (since GPS signals are free), and cellular-powered features should be a shared cost (since cellular data incurs fees). In contrast, Halo collars are non-functional until you pay for and activate a subscription.

With Halo, you may also run into additional fees, which come standard with SpotOn at no cost to you. Here are five examples of Halo’s standard fees:

  • Halo Shipping Fee: $19.99
  • Halo Restocking Fee: $25 (if you return)
  • Halo Charging Kit: $34.99 (the collar has the wire, but no charging block)
  • Halo Beacons: $39.99 each (required to create each keep-out zones)
  • Halo Protection Plan: $9.99/mo + $149-$199 for a replacement collar

When you look at the cost of ownership beyond a year, SpotOn provides more value for less. In fact, Halo's two-year cost of ownership will cost you more.

"The gap in price between the two reflects the gap in quality. The SpotOn collar's design seems to be focused on high-quality components that deliver a high level of precision and accuracy and ultimately a high level of performance, whereas Halo's design kind of seems like it was an afterthought."

SpotOn vs. Halo: Better User Experience

SpotOn’s Fence is Infinitely Customizable

With SpotOn, you can draw your fences on the app or walk them in real time if you desire more precision. SpotOn virtual fences can contain up to 1,500 virtual posts, letting you create fences of any shape or size. Halo Collar’s fence creation maxes out at 20 virtual fence posts, which will be limiting if you have an odd-shaped lot or want to contour your fence to a curved property line.

Halo 4 and Halo 5 take a new approach to fence creation. They automatically set your fence boundary to your address based on a database of deed records. This is an interesting idea in theory, but in practice, users report that it often sets your fence to the property next door and often cannot draw from deed records for newer builds.

Only SpotOn Provides Unlimited Fences for Free

With Halo, users on a basic plan ($9.99 per month) get a maximum of 5 fences. To add more, a pricier Pack Membership is required. With SpotOn, all users get unlimited fences for free and don’t need a subscription to create fences. 

SpotOn GPS dog fence also lets you activate GPS fences individually. Make, save, and activate different fences for different times, seasons, and places. You can create different fence configurations on the same property if you like, such as a daytime fence that includes the woods, and a nighttime fence that goes to the edge of the grass. Because Halo’s fences cannot be activated individually (all are either on or off), you cannot have any boundary lines overlap in any way, which makes creating multiple fences on your property nearly impossible.

In their article, Halo attempts to paint this SpotOn capability as a negative, arguing that it is cumbersome to activate fences manually. In reality, this takes just a moment in the app. 

SpotOn’s Keep Out Zones let you set fences within your fence to keep your dogs out of off-limits areas

SpotOn's Keep Out Zones are GPS-enabled, allowing you to create custom-shaped, off-limits areas within your fences. This feature is free and available to everyone. You can use Keep Out Zones to keep your dog out of the garden, the pool, the chicken coop, or to prevent playtime in the poison ivy patch. Keep Out Zones have a minimum size of 30’x30’. But, unlike Halo 5, which uses Bluetooth Beacons for keep-out areas, SpotOn zones have no maximum size or range and are not restricted to a circle shape. So, you can create a custom-shaped zone to keep your dog out of whatever area you need to. No extra pieces are required, and there is no need to purchase outdoor Beacons, which cost $39.99 each.

SpotOn’s Home Zones offer correction-free zones within the fence

It’s a fact that GPS signals are not as accurate indoors. SpotOn Home Zones are GPS-enabled and let you disable corrections within your home and other buildings. This allows your dog to come indoors without deactivating the fence or removing the collar, so it can go in and out freely without any false corrections.

Halo claims that it “automatically disables fence feedback when the collar detects it is indoors,” but in reality, it’s not so automatic. It does this using a battery-powered Bluetooth Beacon. These beacons emit a circular “safe zone” where corrections are disabled. Each zone will require its own Bluetooth Beacon, which is not included with a Halo 5 Collar and must be purchased seperately for $39.99.

SpotOn’s Home Zones require no extra hardware; you simply set your zone in the App. You can add as many zones as you need and unlike Halo's beacons, you're not restricted to a circular zone. And because SpotOn's Home Zones are in-app, you never have to worry about deactivated zones due to a dead battery.

SpotOn Lets You Create Virtual Fences When You’re Off-Grid

When enjoying time spent outdoors in remote areas, SpotOn’s Off-Grid Mode lets you create fences on the fly in areas without reliable signals. With Halo, you cannot create new fences off-grid. Only pre-saved fences work off-grid, so you’ll need to plan ahead, as new fences can’t be set up without a signal. You also cannot modify Halo fences if you’re in a remote area, so if you enjoy outdoor adventures, this will be a limitation.

SpotOn vs. Halo Tracking Capabilities

Track and respond instantly with SpotOn’s Breach notifications and reports

SpotOn will automatically notify you if your dog leaves and begin tracking its location in real-time, posting location updates in the app. With a new cellular antenna that improves reception by up to 40% in low-service areas and delivers 4× better cell reception than competitors, SpotOn's Nova Edition provides more dependable tracking in remote locations.

If your dog returns to the fence, you will receive an automatic notification. Both Halo and SpotOn offers escape reports (Halo refers to it as feedback responsiveness) so you can see where your dog left, where they went, and where and when they returned. This is helpful for establishing patterns and retraining the dog if needed.

Longer Runtime, Smarter Charging, All-Day Battery Power

Both collars offer very similar battery life and charging time. SpotOn's Nova Edition averages 33+ hours of runtime, or even longer when you activate Extended Battery Life Mode. Halo 5 has 48 hours of runtime, Halo 4 offers up to 30 hours, and Halo 3 Collar offers up to 20 hours. SpotOn takes an hour to charge, while Halo takes a bit longer.

SpotOn's Nova Edition offers several fresh updates that make charging your collar even more convenient. Nova introduces built-in voice alerts and a refined LED battery display that work together to communicate charge status clearly, so you spend less time checking and more time letting your dog roam.

Last, SpotOn includes the wall plug you need to charge your collar in the box. To get a wall plug for Halo, you'll have to purchase the charging kit for $34.99 or supply your own. While this cost is nominal on its own, it adds one more thing to the list of extras that Halo users need to purchase versus SpotOn, which provides everything you need to get started up front with no additional cost.

SpotOn’s Customer Support is Unmatched

When it comes to standing behind your product, companies should SHOW their commitment vs. simply telling customers about it in a tagline. SpotOn embraces this approach and aims to be customer-friendly in every avenue of the company. Here’s how:

  • 90-day Returns - There can be a learning curve when using GPS products. That’s why SpotOn set the standard for the longest return policy in 2023. Halo followed suit in 2025.
  • Warranty Protection - SpotOn offers a 1-year warranty, which includes accident forgiveness if your collar is damaged or lost. While Halo has a 1-year warranty, they sell a care plan at $9.99 per month, which gives customers the opportunity to purchase a discounted collar if it’s damaged or lost. This will range from $149 to $199 and your old collar will be deactivated.
  • Choice - With both collars, cellular data powers the subscription plans and enables two-way communication between the collar and the app, unlocking great features like tracking, escape reports, and more. But what if you live in an area with poor coverage? With Halo, you pay for that subscription plan regardless–at SpotOn, you choose how you spend your money.
  • Free 1:1 Dog Training - Halo Collar has invested a lot of care and attention into their in-app training, which we applaud. However, for dog owners who are newer to training or prefer working with a real person, app-only guidance can feel limiting. SpotOn also has in-app training that's a bit easier to follow, plus all SpotOn customers get a FREE session with a certified dog trainer. These 30 minute one-one-one sessions are virtual and completely tailored to the needs of you and your dog.
  • Top-tier Support for All - Every SpotOn customer has unlimited access to our support team. Halo Collar reserves their top-tier support for those who pay for their priciest subscription tier.

SpotOn’s Values

SpotOn’s Commitment to American Quality, Charitable Giving, Innovation, and Integrity

SpotOn is the Original GPS Fence

SpotOn gathered a team of engineers who created GPS devices for the US military and applied that knowledge to invent the first GPS containment system for dogs. We hold multiple patents and have been in the market since January 2019. We have tested our system with over 100,000 dogs, including independent livestock guardian dogs, rough-and-tumble farm dogs, and wandering suburban dogs. We’ve worked through challenges with durability, technology, and bugs, identifying and resolving many of the issues Halo users discuss online, including poor GPS accuracy and software glitches that result in the dog being corrected where it shouldn’t or not corrected where it should.

USA Built

Badge with a flag with text reading: Designed and Assembled in New Hampshire, USA.

SpotOn is a proud American brand that designs, assembles, and manufactures its products in New Hampshire using domestic and international parts. By choosing SpotOn, you’re not only getting a high-quality product but also supporting local jobs and fair wages for American workers, strengthening our commitment to U.S. manufacturing.

We further our mission of service with USA-based technical customer support, which is available for reliable assistance by phone, chat, or email. As the only GPS fence brand offering discounts to veterans and first responders, we’re proud to have saved military and first responder families nearly $1 million since 2019.

Charitable Giving

SpotOn was built to protect dogs and that commitment goes beyond containment. Guided by our values and a deep respect for animal welfare, SpotOn and our founders have donated more than $1.5 million to organizations dedicated to helping animals thrive, including $350,000 in grants awarded through the SpotOn Gives program since its launch in 2024.

SpotOn Gives offers four grant categories: Shelters, Rescues, Working and Service Dogs, and New Hampshire Community Impact. These grants help nonprifits make a difference every day, and we’re proud to stand behind their efforts to improve the lives of animals across the US and the communities that care for them.

Transparency and Integrity

When it comes to tech products, some companies are in it for the mission, while others aren't as straightforward, and are willing to put down honest companies.

If you are doing your research, we figure you might also check out Halo’s blog on SpotOn – we have too. We’re disappointed to see so many myths, misconceptions, and wholly fabricated details in Halo’s comparison article. Here are a few we would love to clear up!

1. Halo claims that SpotOn issues tracking updates every 20 minutes. This is extremely misleading.

With SpotOn, you can view real-time tracking updates at any time. If your dog is securely roaming within its bounds and your smartphone is locked, SpotOn sends a tracking update every 20 minutes. Why waste battery power sending tracking updates from the collar to the app if you're not even using your phone?

Halo is purposely misleading readers by exaggerating a “performance gap” in tracking, even though Halo and SpotOn systems deliver nearly identical user experiences.

2. Halo also claims that SpotOn issues feedback 20-feet after they've crossed the boundary. This is untrue.

SpotOn issues two levels of tones before your dog reaches the boundary, then emits a vibration (and optional static correction) if a breach occurs. Our third-party data backs up the consistency of SpotOn's boundary warnings.

3. Halo claims that SpotOn issues feedback “indefinitely while in or beyond the warning zone or fence line”. False.

SpotOn stops prevention feedback if the dog turns back to the boundary or away from the boundary. Once outside the boundary SpotOn prevention feedback only lasts 10 seconds not indefinitely.

4. Halo claims "SpotOn’s receiver chip is 33% less accurate" and says this was “Independently verified". This is unverified.

Per the electrical specifications for each collar’s GPS chip, Halo’s position accuracy (CEP) measures 2.5m while SpotOn measures 1.5m. Details about Halo’s independent verification are not stated. Meanwhile, SpotOn has a web page devoted to independent lab testing results.

5. Halo states SpotOn’s collar updates “occur far less often". This is false.

Both collars are updated frequently. Any difference is nominal.

6. Halo claims that SpotOn requires you "to train your dog to memorize any/every fence you may want to create and use". This is also false.

With both collars, dogs are trained to understand the alerts and tones, which indicate the boundary. Halo also claims SpotOn’s training methodology is “based on pain or fear;” however, if you gather the main points of each collar’s training program they’re nearly identical (Halo Training vs. SpotOn Training).

The Verdict: SpotOn Delivers Reliability When You Need It Most

SpotOn has gone through independent lab testing to prove we deliver what matters:

  • Absolute Accuracy - Works as promised with minimal fence line drift, according to the GPS experts.
  • Consistent Alerts - The alerts were issued 100% of the time during lab testing.
  • Pinpoint Precision - Performs just as precise in the presence of trees, buildings, and other multipath conditions.

Tested for reliability and trusted by countless dog owners, SpotOn is the only GPS dog fence backed by experts who pioneered GPS technology. Transparency and reliability set SpotOn apart. While others make vague claims, SpotOn delivers proven results: a 99.3% containment success rate, rapid return times, and consistent corrections. This is why SpotOn remains the trusted choice for dog owners who care.

Your dog’s security is essential, so bring home SpotOn, get more peace of mind for you, and give your dog more freedom.
