EYENIMAL 350 Remote Trainer (1-dog)

With a range of up to 350 yards, 9 adjustable levels of safe, static correction (flash or continuous), and a warning beep, this training collar is a perfect classic trainer for most dogs and training applications. Both the collar/receiver and the transmitter take a user-replaceable battery (included), so there's no need to worry about whether you remembered to charge your unit. We also recommend keeping a spare battery with you and you can easily replace the battery if needed. There is a low-battery indicator on both the collar and the handheld transmitter.

The collar/receiver weighs less than 3 ounces, has no cumbersome external antenna, and is fully waterproof. The handheld transmitter is water-resistant, weighs only 1.7 ounces, and is very easy to use with it's built-in LCD screen.
