Hound hunters have been asking for a long range collar that will not break the bank and SportDog has delivered! The new SD-3200 HoundHunter is the latest collar in the SportDog family of training collars. This SD-3200's new transmitter is ergonomically designed in a pistol grip fashion and it operates on a standard 9-volt battery. The transmitter has a patented GlowGrip™ replaceable handle that allows hunters to easily find and locate the transmitter in low or no-light situations. The HoundHunter™ comes as a 1-dog system, but can be expanded to control up to 4 dogs by adding SportDOG Brand™ SHR-H Add-A-Dog collars. Now as you add dogs to your pack you can add additional collars with ease.
