Product details:

The powerful waterproof collar for pets weighs only 1.3 oz and features a built-in stimulus test lamp and battery tester. These allow you to test your boundary field, and test the functionality of the shock output without using an external test lamp. The collar is water resistant with a water-sealed external speaker, which produces louder, clearer training tones for faster boundary training. The High Tech pet collar, 1ct, comes with both short hair and long hair probes to meet your particular pet's needs. It is a slim, lightweight collar that is designed with comfort in mind. The High Tech Pet Radio Collar for HC-8000 Ultra System comes with a replaceable battery for convenience. The poly-elastomeric strap is integrated with the electronics casing for a slim look. Now you can help keep your pet safe in the confines of your yard without installing a physical boundary.
