After years of hard work, research and dedication to the idea of ​​offering only the best that can be found in the world of electronic training collars, the whole Martin System team is proud to present you a masterpiece -  the CTT 4 / Chameleon® IV!

CTT 4 / Chameleon® IV is a project that started in 2012. Michael and Bart Bellon and the whole Martin System DREAM TEAM dreamed, dared to start and worked hard on it. CTT 4 / Chameleon® IV is another advancement of technology and development of training collars to an absolutely new level. By prioritizing animal welfare without denying negative reinforcement, the Chameleon® IV with CTT 4 transmitter  embodies a revolution in dog training.

The revolutionary and unique feature of the CTT 4 / Chameleon® IV is the fact that through a radio signal, the information from the collar is returned to the transmitter, which gives the dog owner/trainer immediate and invaluable information:

• Contact with the skin
• Radio signal
• Temperature of the collar (dog's body)
• Transmitter/collar(s) battery status indication


In the factory settings, the CTT 4 is tuned as a transmitter for one dog (four different programs/levels for one dog). With the free Doggify mobile app,  the CTT 4 can be turned into a two-dog transmitter, ideal for trainers and multi-dog owners.

Don't wait for change, be the change . With the CTT 4 + Chameleon® IV set, you open a new chapter in training and your relationship with your dog. Order it today and experience the difference that a true revolution brings.
