Listing is for a set of two rechargeable training collars in green. Easy-to-use controls and clear digital display. Designed for reliable remote training with about a 3,000 ft range. Options include loud beeping, variety of vibration levels, and a humane level shock. You can adjust the intensity up to 16 levels on some of these options. Remote can jump back and forth between each collar so you can set it to work on different levels individually for two separate dogs. Comes with a remote transmitter, the two collars, all of the shock option adapters for different fur lengths, the charging cords, plus the shock power tester piece. Full kit with the original box. We originally bought this to utilize with our 45 lb dog, but only used it for maybe a week. Majority of the time you can just use the beeping or vibration options and they are fantastic! Luckily, he's a quick learner so we simply haven't used it in months. Stock photos are from Amazon where we originally purchased about a year ago.
