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.
For the Chameleon® Extenders Martin System, we recommend purchasing a Charging Cable if you do not have one already.
Medium size (26,5 cm) has one central island in the center, two additional islands on each side. One single island can accommodate up to 3 contact points/plastic screws. The final island can support 2 contact points/plastic screws.
