The Aetertek AT-216D Dog Training System is water resistant and features multi-functional modes - warning beep tone, vibration mode & 7 levels of static shock. It covers a 550m control range. It is the only product in the range that allows training of up to 3 dogs from the one handset (requires the purchase of additional receivers). Suitable to train dog weighing from 8kg to 60kg. Static Shock Remote Training Collars deter barking by emitting a safe static shock at the time of your choosing. Unlike automatic training collars, you as the owner are in control of 'when' and the level of shock. This style of manual training works very well if you are training out an issue that is not as repetitive (barking at certain things rather than everything) or to discourage rough play at the dog park, biting, fence jumping etc. Check out our great demonstration video to learn more!
