Remote ball launchers and toy droppers let you reward your dog at a distance, on your signal, to build drive and keep its focus forward.
The Martin System DogTrophy is a remote ball dropper, sold as the receiver alone for handlers who already own the transmitter, or as a set with the PT3000 remote and hands-free Finger Kick, and a vertical stand holds it upright. The Dogtra QL1 is a remote bird launcher for gundog and retrieve training that launches pigeons, doves, small dummies or large balls on command, and comes with a UK adaptor.
