Priced right to train right

An economical favorite, this Innotek Basic remote trainer offers one-button ease of operation. Choose a soft touch or a firm tap, with correction levels from 1 to 7. Need an extra correction? The +2 boost switch will get your pet's attention.

How it works: An electronic collar is keyed to a handheld remote device that you control. You can correct your pet at a distance, when he's out of reach, or otherwise not heeding your commands. Signal your pet with a warning tone only. You can also correct with static stimulation: he'll feel a safe, humane tingly sensation that gets his attention and deters from bad behavior.
