The Pro Trashbreaker extra collar from Garmin and Tri-Tronics works with the Pro Trashbreaker handheld, allowing you to add more dog device collars to your pack. Train up to nine dogs (additional dog devices required) with a range of four miles. The extra collar is enhanced with remote-operated LED beacon lights for low light conditions, and features a built-in BarkLimiter, activated by the dog device, with Auto rise technology, which automatically adjusts correction to the optimum level needed to stop unwanted barking.
It is designed to withstand all the blows that come with training and hunting and is water-rated to 1 ATM. The extra collar comes with two lengths of removable, stainless, insulated contact points for reliable performance in wet conditions and extended comfort for the dog. It features a long-lasting, rechargeable, lithium-ion battery with a battery life indicator so you know when to recharge the system.
