The Canifly First remote control enables you to operate 1 up to 6 CANIFLY bird launchers up to 200 meters (you can add the additional bird launchers at any time). The bird launcher system lets you control the launch of birds or training dummies from metres away and therefore simulate real hunting situations. This system helps train retrievers to remain steady and mark falling birds. It's also great for training pointing dogs to reinforce steadiness when a bird flushes. If you replace the bird by a ball, it might also be used to motivate your dog for jumping. Exclusive to NUM'AXES: a trap door located on the side of the bird launcher allows you to have your two hands available to introduce the bird into the bird launcher.
