Overview
A back yard or training field is where this remote collar gets used, with a handheld transmitter controlling a receiver collar worn by the dog. A finger clicker comes in the title, and contact points for short and long hair are included.
The wide level range lets you start low and find the dog's working level. Vibration, a night light and sound give alternatives to stimulation. The listing does not give a neck fit range, so measure first.
Who it's for
A small or medium dog in obedience training outdoors is the situation. Dogs that need an automatic bark collar, and owners who prefer no electronic aids, should look elsewhere.
Pros and cons
- Fine stimulation level range
- Vibration, light and sound options
- Waterproof and rechargeable
- Contact points for both coat types
- Neck size range not listed
- Small and medium dogs only
- Training skill required
- Accessories carry a shorter warranty
Performance notes
The transmitter sends a signal to the receiver, where a tapping stimulation at the chosen level reaches the dog through the contact points on its neck. Hair length changes contact, so the right contact points matter. Training results depend on consistent timing and rewards.
