Loading and Unloading birds for training your pointing/flushing dog has been made simple with this revolutionary new "Natural Flush Bird Launcher" DT Systems' "easy-load" trap door allows you to set the launcher, lock it in place and then load the bird. This exclusive feature lowers the chance losing the bird while trying to put him in the launcher and locking the springs. It also makes it very easy to load multiple birds in the same laucher to give more of a "covey rise" effect. The DT Systems launcher has a "Quiet Release" system to keep from "spooking" your dog. You still get a very strong launch but little sound and virtually no movement of the launchers palcement The DT Launchers also have a safety lock feature for use after the springs are set. This allows you to lock the springs, set the safety, load the bird and then carry the unit into the field without concern of the launcher going off in transit. After you have placed the laucher in the location, remove the safety lock and arm the remote release. Your bird launcher is now ready to use. Large Scent Holes in the DT bird launcher permit good air flow so dogs have the advantage of plenty of scent to help them locate the bird. The Remote Natural Flush Bird Launchers allow you to control up to 16 self-programmable Bird Launchers from up to 700 yards away. A beeper attached to the Remote Launchers allows for quick and easy location with a touch of a button from your transmitter. This is a very handy feature when you are working with several bird launchers in a large area. At the end of your training session, you can activate the beeper locator to go back and pick up your launchers. DT has a battery saver feature that shuts down the system after it has lauched the bird, but the remote beepers will work even when the launcher is shut off. Both the transmitter and receiver use standard nine volt batteries (not included) 1 year warranty. Note: We do not recommend the use of ANY spring loaded "catapult" type launchers in introducing pups to birds. You are better off to use planted birds when you are introducing young dogs to birds. Launchers are best suited for dogs that have been introuduced to birds and are very interested in them. We also recommend that all dogs be on a check cord or otherwise under complete control when using spring-loaded "catapult" type launchers. Flushing birds with remote "catapult" type launchers is the closest thing to training on wild birds. Better yet, you can control the location of the birds and when they will flush with remote launchers. When steadying a pointing dog to wing and shot, using two or more launchers at the same location can help maintain the dog's interest and intensity after the initial flush. An occasional second and third delayed flush will help the dog anticipate additional flushes on all points and, therefore, help maintain its interest and its intensity longer. Additional Launchers can also be used for the delayed second and third flushes.
