Innotek IUC-4100 UltraSmart In-Ground Pet Fencing

Innotek's exclusive ReadyTest(TM) produces a brief pleasant clicking from the collar to assure you of perfect collar fit, and indicates the system status and battery status of the receiver collar. Waterproof -- Collar and transmitter stand up to rough punishment, even submerged in water. The new, rechargeable lithium ion batteries charge in only two hours and maintain their charge for weeks at a time. Patented Run-Through Prevention (correction level automatically increases as your pet approaches the boundary) and timeout between corrections help your dog learn limits quickly and safely.
