The Chameleon® Extender is NOT an e-collar !
The Chameleon® Extender turns your one brick collar into a two bricks utility collar. The Extender allows you to have more than one positive and negative contact point. Additionally, you can move/add your contact points for optimal contact and best sensitivity for your dog. Contact points can be moved as frequently as necessary to eliminate necrosis possibilities.
The Chameleon® Feather Contacts are compatible with the Chameleon® Extenders, they give the best contact with flexible comfort.
The Chameleon® Extender Multi Brand Compatible (CEMB®) is available in Medium size (28,5 cm) and Large size (34,5 cm).
*Measurements do not include any part of the elastic or the Perfect Fit Closure.
