ReadyTest feature offers everything you need to ensure that your pet is safe and comfortable.
- Right collar fit indicator:
- Whether training your dog at the park or playing in the yard, your dog's comfort and safety relies on a proper collar fit. Don't guess. Make sure with ReadyTest. This patented advanced safety system produces a brief audible click from the collar to assure you of perfect collar contact.
- On-board systems check:
- Don't leave your dog's safety to chance. UltraSmart collars alert you to potential problems before it's too late. After charging, UltraSmart collars automatically perform a vital systems check to ensure proper operation of the power and electronic circuits. A green light means all systems are functioning properly and a flashing red light indicates there is a collar problem.
- 3-way battery indicator:
- Never run out of battery power again. ReadyTest monitors battery levels in your dog's collar. Green is more than half a charge, yellow means less than half and red means charge the collar at the next opportunity. Operates on Lithium Ion batteries.
