The system comes with a smart collar that is IP67 WATER RESISTANT and a MOBILE APP. All you have to do is install the mobile app on your phone and place the Halo Collar around your dog’s neck. Coupled with that, the collar is also CHEW-PROOF.

It has 15 static correction levels, (more than most systems in the market) which can be adjusted based on preference and opted training.

This system is GREATLY AFFORDABLE compared to other products on the market. If you are on a budget, this could be your best invisible fence system. Even the subscriptions are affordable, making this a very budget-friendly product.

You can create MULTIPLE virtual fences, ½ acre or larger..

There is no static correction, (the system uses vibration, audible cues and ultrasonic sounds) making this a more HUMANE alternative.

The HEALTH and ACTIVITY tracking feature is seamless. The system will track your dog’s movement and make recommendations to improve well-being, such as sleep time. 

The collar is WATER RESISTANT (rated IP67), which is great if your dog loves swimming.

How Does an Invisible Fence Work?

a dog wearing invisible fence collar and lying on the ground

An invisible fence uses GPS or radio signaling to designate a safe zone for your dog. The safe zone is defined by installing an underground wire or using a mobile app or transmitter. 

The invisible fence keeps your dog safe and uses tone and/or static correction to achieve this. 

For more stubborn dogs, the static correction feature will help you train them better.

Once installed, the receiver collar will trigger every time your dog leaves the designated boundary. 

The concept is simple and attractive. It takes away the hassle of having to build a physical fence.

Types of Invisible Fences

There are three main types of invisible fences.

The first type uses an UNDERGROUND WIRE, which should be installed along your boundary line for the system to work. The Extreme Dog Fence is an example of this type of invisible fence. 

The second type uses an IN-GROUND TRANSMITTER, which doesn’t have to be buried. Systems like the PetSafe Stay and Play Wireless Pet Fence work using this technology (designating a circular dome safe zone.)

The third type uses GPS, which lets you track your dog using a mobile app. Systems like the Halo 2+ dog collar are great examples of GPS-enabled systems.
