This unit can be used to replace a lost remote/transmitter. Or because the SD-425/SD-425S systems are fully customizable, you can add it to your existing system to set 2 or more transmitters to control the same collar receiver (consult your Owner’s Manual for set up instructions).

If you already have a SportDOG containment system and would like to upgrade it to allow training functionality, simply purchase an SDF-CTR Collar/Receiver along with this SDT54-13889 handheld transmitter. The SDF-CTR collar will work with your existing SportDOG containment system to contain your dog, and your SDT54-13889 transmitter will allow for remote training, all with a single contain-n-train collar.
