The LCS Universal Launcher 2-Button Transmitter is designed to synchronize with LCS Universal Bird Launchers or LCS Remote Backing Dogs that are equipped with receivers. This transmitter operates two LCS dog training devices: two bird launchers, two backing dogs or one of each. Constructed from durable plastic, including the built-in antenna, is water resistant and small enough to hang from a lanyard. Easy to operate even with gloves on, you simply select the training device on the up/down switch on the left hand side of the unit, then press the white button in the middle of the front to deploy it. Rely on tried and true LCS electronics to simplify and modernize your dog training routine.
