Quick Comparison of Halo Collar 4 vs Halo Collar 5
Here’s a quick side-by-side rundown of the major features and their differences. You may also want to check out my Halo Collar 4 review and my Halo Collar 5 review for more details.
| Category | Halo Collar 4 | Halo Collar 5 |
|---|---|---|
| Virtual Fence Features | Customizable GPS fences, accurate but limited to single-frequency GPS. | Adds dual-frequency GPS for tighter accuracy, especially in tricky areas. |
| GPS Tracking Features | Solid GPS tracking but with occasional very minor lag. | AlwaysOn™ GPS with 20 updates per second—virtually real-time tracking. |
| Battery Life | Average of 30 hours per charge. | Up to 48 hours per charge and faster 1-hour full recharge. |
| Connectivity | Combined Wi-Fi/Bluetooth chip, reliable but not flawless. | Separate Wi-Fi and Bluetooth chips + global all-carrier coverage. |
| Pricing | Premium price with required subscription plan. | Slightly higher upfront, but added features justify the value. |
| Design | Reflective, waterproof, rugged—well-received design. | Identical external design; all changes are internal improvements. |
| Training Features | Built-in training with Cesar Millan and customizable feedback. | Same training system—no new features, just as reliable. |
Virtual Fence Features
Both Halo Collar 4 and 5 let you create customizable GPS fences, but the 5 adds dual-frequency GPS for even tighter accuracy. The basic functionality hasn’t changed—just the precision and reliability.
With Halo Collar 4, you could already create, edit, and store unlimited fences as small as 30×30 feet, which worked well for most yards. Halo Collar 5 builds on that foundation by adding dual-frequency GPS (L1 & L5 bands), which reduces signal interference and keeps your dog’s boundaries more consistent.
If you live in an area with trees, buildings, or other GPS obstacles, the difference in precision is noticeable.
GPS Tracking Features
TL;DR: Halo Collar 4 offered solid GPS tracking, but Halo 5 takes it to near real-time updates with AlwaysOn™ GPS. The new model is designed to virtually eliminate lag in location reporting.
The 4 did a good job of letting you know where your dog was, but it could sometimes feel a little behind in fast-moving situations. Halo Collar 5, with its 20 location updates per second and AlwaysOn™ GPS, feels like a true real-time tracker.
This upgrade is especially helpful for dogs like Freya who can bolt after prey in seconds—you’ll see where they’re headed almost instantly.
Battery Life
TL;DR: Halo Collar 4 averaged around 30 hours per charge, while the 5 boosts that all the way up to 48 hours. The 5 also charges fully in just about an hour.
Battery life was one of the few areas where 4 lagged behind some competitors. While a full day was workable, frequent recharging could get old fast. Halo Collar 5 fixes this in a big way with a 48-hour battery that doesn’t just last longer but also charges much faster. That means less downtime and less worry about your dog’s collar dying mid-adventure.
Connectivity
TL;DR: The 4 used combined Wi-Fi and Bluetooth chips, while Halo Collar 5 separates them for a faster, more stable connection. The 5 also supports all-carrier worldwide cellular coverage.
Connectivity is the backbone of any
Design
As you can see in the pics above, Halo Collar 4 and 5 look exactly the same on the outside. Halo decided not to mess with a design that already worked well.
Both collars share the same size range, reflective striping, rugged waterproof build, and overall feel. Since users had no major complaints about comfort or durability with the 4, the company wisely kept the design unchanged for the 5. All the improvements are internal, so your dog won’t notice the difference—but you will.
Training Features
Both collars come with the same built-in training program designed with Cesar Millan. Halo Collar 5 doesn’t add new training functions but keeps the proven features intact.
Halo Collar 4 already included customizable feedback options (sound, vibration, static) and access to the Cesar Millan training program within the app. The 5 maintains the same training features, so if you liked the system before, nothing changes here. The focus of this upgrade cycle was on GPS, connectivity, and battery life rather than behavior training.
Pricing
Pricewise, the Halo Collar 5 currently costs $50 more than the 4, which makes sense since it’s the newer of the two. That said, it’s still priced extremely competitively, and significantly lower than the original model (or even the 2 and 3) back when it debuted years ago.
