Extra collar/receiver/beeper for the SD-1850 unit.  The SDR-BEEP is a serious piece of engineering that will matter most to those it was designed for, Upland Hunters. Unlike any other product in the category, this remote beeper does not depend on a training collar to operate. You can use your transmitter to operate the remote beeper by itself, the training collar by itself, or both together if you need them. This is a flexible training/hunting accessory that will fit your style. If you own a SportDOG UplandHunter 1850, the 1850 transmitter will operate all SDR-BEEP training collars and beeper functions remotely and allow you to run a second dog. SportDOG Brand, Gear the way you'd design it.
