The Blue fang® X-22 is a complete electronic fence kit with remote training and bark. Blue fang® technology lets you control your dog’s collar with your iPhone or Android from 400 ft. Comes with BF-22 collar, transmitter, 500′ of ultra-wire, 50 flags, waterproof splices and mounting hardware. The perimeter is expandable to 50 acres with purchase of additional wire. Pulsed Proportional Stimulus™ prevents run-through by automatically increasing stimulus as your dog moves toward the boundary for the most effective and humane electronic dog fence made. Remote training uses positive tones to quickly and easily teach good dog behaviors such as sit, stay, come and heel. 3 corrective stimulus levels deter bad dog behaviors like jumping, chewing, and digging. Add an unlimited number of collars and customize the stimulus intensity and duration of each level for each individual dog. Bark stopping function distinguishes between nuisance barking and intruder/ alarm barking. 3 Bark Control Modes: Stop Only Nuisance Barking, Stop All Barking and Stop Barking and Howling. 3 corrective stimulus modes, Sound Only, Stimulus Only and Sound Plus Stimulus. The Sound Only mode uses painless sound to gently but, effectively deter. The quicker-acting static stimulus modes use a warning tone followed by harmless static stimulus that starts out mild and increases if barking persists. Easy to use, just download the free app for real-time installation and operation instructions on your phone. Electric fence in-ground installation takes 3 – 4 hours. Ultra-Wire lets you install above ground in less than an hour. Blue fang technology automatically transfers new firmware to the collar with each app update for new and useful functions when available which may include Invisible Leash, Doggie Fitness Training, and hundreds of others currently being developed by High Tech Pet. The X-22 will improve the way you communicate with your dog, making him a safer, better behaved and happier pet.
