5150G- ULTRASONIC TRAINER Product Details: No collar needed “Select-A Sound” Lets you choose one of five ultrasonic tones your dog best responds to Use ultrasonic tone to divert your dog’s attention from bad behavior Manual or automatic correction modes Works at distances up to 25 feet Safety time-out feature Low battery indicator Disposable Batteries The hand-held Havahart Ultrasonic Basic Dog Trainer is used to correct your dog’s misbehavior such as jumping on furniture or counters, digging, chewing and bark control. As the name implies, the Ultrasonic Basic Trainer works by emitting a loud, ultrasonic sound that, while inaudible to you, is heard only by your dog and distracts him. The trainer is effective with any dog 6 months and older, and any size and breed. However, it is important to realize that only about two-thirds of all dogs will respond to ultrasonic training. Some dogs will not be distracted by ultrasonic frequencies. Adjust to Your Dog’s Hearing Sensitivity The high frequency correction is silent to the human ear, making the unit truly ultrasonic. With Select-a-Sound, the trainer can be tuned to one of 5 different sounds to match your dog’s unique hearing sensitivity. Two Training Modes The dog obedience training device can be used in Manual or Automatic mode. In Manual mode, simply press the Correction button whenever the unwanted action takes place. In Automatic mode, the trainer can only be used to correct excessive barking. The trainer has been programmed to recognize a full range of barking sounds produced by all size and breeds of dogs. Set the trainer near your dog and when a bark is detected, the trainer will emit the pre-selected ultrasonic sound. Safety Features If the trainer is being used in Automatic mode and is triggered six times within one minute, the trainer will go into “time out” mode and cease all corrections for five minutes.
