- Quick Start Slip with a QR code for app setup
- Charging Block with a special design different from earlier models
- USB-C Charging Cable (USB-C on both ends)

Item | Description |
---|---|
Quick Start Slip | QR code for easy mobile app setup |
Charging Block | Custom design, not like older versions |
USB-C Cable | Plugs into new charging block |
Probes | For adding static function if needed |
Perfect Fit Parts | Helps fit the collar and includes end caps |
Collar 4 | With removable sleeve and new flex point |

Simple Steps to Get Started
The first step is scanning the QR code on the slip. This takes them right to the app for setup. The collar features a new charging method, so they used the USB-C cable and the new square-shaped charging block.
They noticed the collar fit better thanks to the flexible section in the middle. This helped with dogs that have smaller necks. The sleeve on the collar is velcro and can easily be removed if wanted.
Setup moves quickly by following the app’s step-by-step directions, and the collar is ready to use soon after charging.
Main Highlights and Notable Improvements
Advanced Dual-Band GPS Support
The collar is now equipped with new dual-band GPS. This means it can track your dog’s location more accurately, even in places where tall buildings or thick trees might otherwise block the signal. This upgraded system collects data from more than one signal from a satellite at the same time, which helps avoid signal loss in busy cities or deep forest areas. Expected location accuracy can be within 6 feet under ideal results, making it a strong option for dog owners in environments with possible signal interference.
Key Points:
- Uses two frequency bands for better signal stability
- Improved location tracking in wooded and urban areas
- Designed to reduce errors from obstacles like trees and buildings
Better Sizing and Comfort
A new flexible section has been added in the middle of the collar, allowing it to bend more easily around smaller necks. This makes it suitable for neck sizes from 8 inches up to 30.5 inches. The collar can now fit more types of dogs, especially smaller breeds that might not have fit into previous models. The Flex Point in the design is a simple upgrade but makes a big difference for comfort and secure fit.
Collar Version | Smallest Neck Size | Largest Neck Size |
---|---|---|
Previous Model | 10–11 inches | Not specified |
Current Model | 8 inches | 30.5 inches |
- Supports a wider range of dog sizes
- Improved comfort with flexibility in design
- Better fit for pets with small necks

Longer Use on a Single Charge
Battery performance is improved, giving up to 30 hours of use compared to 24 hours in the older model. Users notice they can go almost two days between charges, even with active dogs. This longer battery life adds convenience and makes daily use easier.
Improved Battery Details:
- Up to 30 hours on one charge*
- Longer lasting than previous version
- Useful for active dogs that spend a lot of time outdoors
*Actual time may vary depending on use and conditions.
Dog Collar Size and Fit
The latest version of the collar can adjust to fit neck sizes from 8 inches up to 30.5 inches. This wide range is possible because of a new flexible section in the center. The flexible point lets the collar curve and tighten enough for small dogs with necks as tiny as 8 inches. This is an improvement over the previous model, which only fit neck sizes down to about 10 or 11 inches.
Fit Range:
Collar Version | Smallest Neck Size | Largest Neck Size |
---|---|---|
Halo 3 | 10 inches | 30.5 inches |
Halo 4 | 8 inches | 30.5 inches |
Owners who have small breed dogs now have more options because the collar can comfortably fit even dogs with very slim necks. The collar is not too bulky for little breeds and doesn’t lose its snugness when adjusted to a smaller size.
GPS Tracking Reliability in Different Settings
The collar uses a new dual frequency GPS system. This means it can receive two types of signals from satellites at the same time. The benefit is better performance and fewer lost signals in challenging spots like areas with thick trees or neighborhoods with tall buildings.
Key Points:
- Better signal under heavy tree cover or near large structures.
- Reduces issues from weather interference, but strong storms and thick forest areas may still cause some signal drops.
- The system is designed to be accurate within 6 feet, though real-world use may see slight changes depending on the environment and the dog’s activity.
Environment Performance Table:
Environment | Signal Strength |
---|---|
Open Areas | Very Good |
Light Tree Cover | Good |
Dense Forest | Fair |
Urban (Tall Buildings) | Good |
Stormy Weather | Fair |
The dual frequency GPS helps the collar keep its signal even when the dog moves in and out of tricky areas, making it more reliable for many locations compared to older models.
User Experience and App Integration
Key Elements of the App Layout
The Halo 4 app is designed so users can easily find what they need. The main dashboard gives a clear view of your dog’s status and collar information. Buttons and labels are large and simple, which helps even if you are new to technology.
A quick setup is possible by scanning a QR code that comes with the collar. Most important options, like fence setup and dog activity tracking, are visible right away on the home screen. There are easy ways to adjust collar settings and check battery level.
Visual learners benefit from many images and short videos within the app. Guidance is direct and organized, making it simple to navigate whether you are setting up for the first time or making daily checks.

Help and Learning Tools in the App
Support is built into every part of the app. Users can access a library of short videos and step-by-step guides right in the menu. These resources answer common questions about setup, fence creation, charging, or using the collar’s features.
A special focus is placed on offering visual aids, which helps people learn faster. Well-known trainers, like Cesar Millan, provide many of the video lessons. This brings extra trust to the instructions.
For quick questions, there is a list of common topics and answers in the app. Table below shows what users may find:
Type of Support | Where to Find It |
---|---|
Video Tutorials | App Help Section |
Written Instructions | App Menu and Guides |
Trainer Tips | Featured in Videos |
FAQ | Help & Support Tab |
Users can move between learning materials with a simple tap, making the process smooth and frustration-free.

Things to Think About
- Charger Compatibility: The charger is only made for the Halo Collar 4. Older chargers from past models do not work with it.
- Weather and Signal: In very bad weather, or under very heavy tree cover, the signal might drop or become spotty.
- Not True Universal Fit: While the collar fits smaller dogs now, very dense woods may still cause tracking issues.
Note: The main improvement is the new GPS system, which helps fix some problems seen in earlier models, especially with signal in tough environments.
Price and Value Considerations
When looking at the Halo Collar 4, it helps to consider both what you are paying for and what you actually get in return. This model comes with several feature upgrades, like the new dual-frequency GPS, the improved battery life, and the ability to fit smaller dogs thanks to the flexible center.
Key Features and Value:
Feature | Value for Buyers |
---|---|
Dual-frequency GPS | More accurate tracking, better in cities and woods |
Battery life (up to 30 hours) | Longer use between charges |
Fits necks 8″-30.5″ | Works for a wider range of dog sizes |
Perfect Fit System | Easier and more comfortable fit |
Pros that Add Value:
- Accurate in tough environments like cities and forests
- Easy to set up, use, and adjust for different dogs
- More time between charges means less hassle
Considerations:
- The charger is specific to this model and cannot be shared with older versions
- In very heavy weather or dense woods, signal can still drop at times
The upgrades help explain the price, as buyers are getting new technology and more flexibility. The value comes from knowing that the collar can now work for more dogs, last longer, and track better than before.
