The SportDOG SDR-Beep does not rely on a remote trainer to operate.  This unit includes a training receiver and a removable beeper accessory.  This gives you maximum flexibility when working with your dog.  The SDR-Beep is the same collar receiver that comes with the SportDOG 1850, but includes the modular remote beeper.

Note: If you own one of the following systems, your transmitter will operate the DSR-Beep training collar and the remote locate or "call" function on the beeper:  SportDOG 1800, SportDOG 1850, SportDOG 2000 CAMO and the SportDOG 2500.

Note:  If you own a  SportDOG 1850 model, your transmitter will operate all SDR-Beep training collar and beeper functions remotely and allow you to run a second dog.
