Radial-Shape2 Havahart® Wireless Extra Collar

The Next-Generation of Wireless Pet Fencing
Stretch the boundaries of wireless dog fencing with the next generation Radial-Shape2 Havahart® Wireless Dog Fence--the industry's most advanced do-it-yourself, dog containment system that is easy to use and is economical. With over 10 new product updates and enhancements this is truly the newest generation of wireless pet fencing!
System: The upgraded software coupled with new engineered hardware creates a better quality, more reliable signal and response between the controller and the new universal collar. This enhanced digital communication through precision tuning allows for an easier and faster set up procedure for you…less than an hour for set up.
Collar: Enhancements have also been made to the water resistant Collar which include a new battery cap design that is flush with the battery housing, providing a more secure fit. The improved strap is made of heavy-gauge nylon webbing with a ¾ snap buckle closure. The collar fits neck sizes 14” to 26”.
Service: Coupled with these enhancements we have redesigned our Consumer Care team to be focused on you. The set-up is easier but we also want to be here if you need us, so our Consumer Care team is well prepared to help you seven (7) days a week. We have streamlined the process to help minimize your time on the phone. We can even set up an appointment time to walk you through the installation of your fence (some time restraints apply).
Cutting Edge Technology
The Collar harnesses the next generation of wireless fencing technology. Patented antennas integrated into the rubberized collar strap provide a reliable path of constant communication to the Controller. This enables the System to track the real-time distance to your dog, alert you if your dog breaches the wireless electric fence boundary or if the Collar’s battery is low. Integrated Motion Sensor Technology allows the Collar to conserve battery life when your dog is not moving.
Collar Design
Our comfortable water resistant Radial-Shape Havahart® Wireless Electric Dog Collar maximizes the safety and freedom of your dog. The new collar strap is made from heavy gauge nylon webbing that houses the patented antennas and has a durable 3/4 inch snap buckle closure. The Collar fits dogs with neck sizes from 14-26 inches.
The battery cap has been redesigned to be flush with the battery housing and requires a coin to open and tighten the cap, in order to secure the battery in place. The total collar weight is 3.7oz. The wireless fence system can accommodate up to 2 Collars.
Customizable Settings

Using the Controller, the Collar can be programmed to tone only (auditory correction) or one of 5 different static correction levels depending upon the size, age and temperament of your dog. The default correction level is tone only. The Collar should not be on your dog for more than 12 consecutive hours.
Easy Set Up

With the touch of a few buttons, the Collar can easily be paired to your System. Long or short Probes (included with your System) can be used depending upon the thickness of your dog’s coat.
Safety Features
Havahart® Wireless created a wider Trigger Zone- 6 to 13 ft- to keep your dog safe and away from danger.
The Collar is designed with a Safety Time-Out Feature that stops the correction cycle (a series of static pulses) after 30 seconds. After the correction cycle times out, your dog will not be corrected for returning to the Roaming Area. Once your dog returns to the Roaming Area the Collar will revert to its normal operating mode and correction will occur only if he again enters the Trigger Zone.

Advanced Technology Makes it All Possible
The Radial-Shape Havahart® Wireless Dog Fence is driven by nanoLOC TRX 2.4 GHz transceivers that have been enhanced with complex algorithms, strategic distortion filtering and modular signal amplification.
These enhancements boost the performance of the Havahart Wireless Dog Fence systems over the competition by providing enhanced signal strength, smarter filtering cabailities and more reliable communication, delivering advanced time-of-flight-ranging technology.
Havahart® Wireless dog fence systems use the Kalman Filter, the same data-filtering technique used by NASA. Through advanced analysis, Havahart Wireless systems are capable of rejecting the statistical anomalies that can result in a fuzzy boundary.
This analysis, combined with the appropriate hardware and software, pushed the nanLOC transceiver to perform beyond its standard capabilities.
This translates into a crisper boundary, giving the Havahart® Wireless electric fence systems the ability to maintain constant signal strength throughout the entire electric fence boundary.
What truly sets the Havahart® Wireless electric fence system apart from the rest and defines how a wireless electric fence should really work, is its patented time-of-flight ranging technology.

Time-of-flight is the time it takes for a signal to travel from
a the Controller to the Collar and back at the speed of light. By continually communicating to the Collar, the Controller is able to track the real-time distance to your dog.

Based on the data that is continually captured, filtered and refined, the Controller will determine whether or not a correction should be delivered. Better yet, with motion sensor technology, if your dog isn’t moving while in the Roaming Area, the sampling rate becomes less frequent, saving battery life.
These enhancements comprise the core of the patented elements that provide an unparalleled level of technical sophistication in the wireless dog fencing industry.

Works great! Easy to setup and tailor the settings to my yard. My only complaint is that the collar is a buckle not a snap clip collar. This makes it harder to put on and take off.
Reviewer: David Young
We have a 7 month old male labrador (fixed) and live in a rural, mountainous area. Larger dogs tend to run free where we live, within reason. We also tend to have a lot of domestic dogs running around, in a good way. But they all enable each other to stray a little.
Our new puppy was wandering some pretty impressive or offensive distances and it started to become a problem early on. So we bought this wireless fence, and the results have been good but not perfect.
The 400 foot radius is awesome, we only use 250. The system is very easy to use and configure, no issues there. At 400 feet, your dog will have plenty of room to run.
We did the flags and training with him at 250 feet.
It kept him fairly in check pretty fast. I took the shock myself on its highest level. The shock on me did work, but I thought it would hurt a lot more that it did. It was very "mildly unpleasant" for me, nowhere near enough for me to drop the collar or anything. I'm 200 pounds, he's maybe 25 pounds. But I was still expecting more. This will not hurt your dog, don't worry about that.
So make sure that collar is tight when they're outside. I can see fur blocking a lot of the shock.
But if there is a rabbit and he feels like making a run for it, or a jogger who he'd like to join, he will bust through. Probably typical puppy-hood. But his wandering has been cut way, way down. He at least knows where his boundaries are.
On a scale of 1 to 10, 10 being he never leaves his land without his collar EVER, I'd give it an 8.
