AUTOPROX™ is Heel's proprietary proximity-based training technology that creates a moving, customizable Virtual Leash™ radius around the owner. Instead of relying on GPS, WiFi, or a physical fence, AUTOPROX™ constantly measures the distance between the dog and the handler and automatically delivers gentle training cues when the dog reaches the edge of the safe roaming radius.

How does AUTOPROX™ work in the Heel Virtual Dog Leash™ system?

In the Heel Virtual Dog Leash™ system, AUTOPROX™ uses a wireless connection between the collar and the handheld controller to monitor the dog's distance in real time. When the dog approaches the edge of the set radius, AUTOPROX™ automatically delivers a tone as a recall cue. If the dog continues outward, a vibration cue follows, and optional low-level static can be enabled as a last layer. All cues stop immediately when the dog turns back toward the owner, helping the dog learn to stay within a safe, predictable distance.

What cue sequence does AUTOPROX™ use?

AUTOPROX™ always uses the same consistent cue sequence: tone first, vibration second, and optional static as a final backup if the owner has enabled it. Tone is the primary recall signal and is usually enough for most dogs once trained. Vibration serves as a stronger boundary reminder if tone is ignored. Static stimulation is adjustable, low-level, and off by default, and Heel™ works fully without static enabled.

How is AUTOPROX™ different from GPS dog fences and wireless fences?

AUTOPROX™ is different from GPS dog fences and wireless fences because it creates a moving boundary centered on the owner rather than a fixed perimeter in a specific location. It does not require GPS, WiFi, or a cellular signal, and there is no subscription fee. GPS and wireless fences can be affected by lag, signal drift, terrain, trees, and buildings, and some may continue static stimulation until the dog re-enters the boundary. AUTOPROX™ works in real time wherever you go and stops cues immediately when the dog turns back, making it better suited for hiking, camping, and off-leash adventures.

Is AUTOPROX™ the same as a traditional e-collar or shock collar?

AUTOPROX™ is not the same as a traditional shock collar, even though it uses similar hardware to an e-collar. Traditional e-collars and shock collars rely heavily on manual button timing to interrupt unwanted behaviors and often use static as the primary tool. AUTOPROX™ is a next-generation, proximity-based system that focuses on distance awareness, recall, and off-leash safety instead of punishment. It automates cue timing based on distance and uses tone-first and vibration-first cues, with static as an optional, low-level backup that is off by default.

Is AUTOPROX™ safe for dogs?

AUTOPROX™ is designed with safety and humane training in mind. Cues are delivered in a predictable sequence of tone, vibration, and optional static, and all cues stop as soon as the dog turns back toward the owner, which helps prevent overstimulation. Static stimulation, if enabled, is adjustable, low-level, and not required for the system to function. When used correctly and paired with proper introduction training, AUTOPROX™ helps dogs understand their safe roaming radius without relying on constant or unpredictable corrections.

Where does AUTOPROX™ work best?

AUTOPROX™ works best in real-world environments where owners want controlled off-leash freedom, such as hiking trails, camping areas, cabins, fields, forests, and large outdoor spaces. Because it does not depend on GPS or cell service, it functions reliably in places where many GPS-based systems struggle. This makes the Heel Virtual Dog Leash™ with AUTOPROX™ a strong option for dog owners who want a portable, wireless boundary solution for everyday adventures.

How AUTOPROX™ Works

AUTOPROX™ is Heel’s proprietary proximity-based training technology that automatically helps your dog maintain a safe, predictable distance — without GPS, WiFi, or a smartphone app.

It is what transforms Heel™ from a traditional e-collar into a true Virtual Dog Leash™.

Where shock collars depend on manual correction and GPS fences depend on location signals, AUTOPROX™ uses real-time proximity sensing to deliver consistent, automatic cues that guide your dog safely back toward you.

What AUTOPROX™ Does

AUTOPROX™ automatically:

Detects your dog’s distance from you in real time
Determines whether your dog is nearing, reaching, or crossing your safe roaming radius
Sends a predictable sequence of training cues (Tone → Vibration → Optional Static)
Stops all cues immediately when your dog begins returning

This creates a safe, intuitive feedback loop that your dog quickly learns.

The AUTOPROX™ Cue Sequence

AUTOPROX™ always uses cues in the same consistent order:

1. Tone (Primary Recall Cue)

A clear audio signal that tells your dog, “Return to your person.”

Most dogs are able to learn to return based on tone alone.

2. Vibration (Boundary Reminder)

If the tone is ignored, a gentle vibration reinforces that your dog is nearing the edge of their allowed distance.

3. Optional Static (Safety Backup)

Adjustable static stimulation is available if you intentionally enable it.

It is off by default, and Heel™ works perfectly without static.

Unlike many wireless fences, AUTOPROX™ stops static immediately when your dog turns back, preventing overstimulation.

How AUTOPROX™ Determines Distance

Heel’s collar communicates continuously with the handheld remote using a proprietary short-range signal.

AUTOPROX™ evaluates this signal at all times, calculating whether your dog is:

Inside the safe radius
Approaching the boundary
At the boundary
Exiting the boundary

It then adjusts cues automatically — no timing mistakes, no manual button pressing required.

Why AUTOPROX™ Is Different From GPS and Wireless Fences

Most wireless fence systems rely on GPS or radio frequencies that can drift, lag, or lose signal due to:

Trees
Hills
Weather
Buildings
Cloud cover

Those systems can:

Shock a dog even when they are inside the boundary
Continue shocking until the dog re-enters the “safe zone”
Fail in forests, mountains, and heavy cover

AUTOPROX™ has none of these issues.

It works:

Instantly
Reliably
Anywhere you go
Without a subscription
Without needing cell or satellite signal

This is why Heel™ is trusted for hiking, camping, and even off grid off-leash adventures where GPS collars struggle.

Stopping Cues Immediately (A Key Safety Difference)

One of the core safety features of AUTOPROX™ is immediate cue cancellation:

All cues — tone, vibration, and optional static — stop the moment your dog turns back toward you.

This prevents overstimulation and makes training more humane and intuitive.

It also differentiates Heel™ from some wireless fences whose static continues until the dog fully re-enters the boundary.

The Learning Process

Dogs learn the AUTOPROX™ system quickly because:

Cues are consistent
Feedback is immediate
The sequence never changes

Most owners report that their dog responds to tone alone after just a few training sessions.
