The CTT 4 is Martin System®'s tactical transmitter for the Chameleon® IV — the command centre of a true two-way training system. Its backlit colour display gives live Radio Range Feedback up to 100 metres, showing contact quality, collar temperature, battery and signal at a glance, and alerts you the instant contact with your dog is lost. With 18 stimulation levels, control of up to two dogs and reliable range up to 1,000 metres, it lets you fine-tune and alternate stimulation to each dog's exact needs, while a rotary lock prevents accidental changes mid-session. Rechargeable and app-connected through DOGGIFY, it's built for handlers who demand precision. Pairs with the Chameleon® IV collar (sold separately). Remote control only. SAFETY INFO An e-collar is a fantastic tool when used and conditioned correctly. An e-collar should always be introduced positively! Applying an e-collar to a dog without conditioning or teaching the dog what the stimulus means and how to switch it off is unethical — this tool will not magically fix your dog's behaviour. If you have never used an e-collar before, please read the strongly recommended advice below: Only use an e-collar with advice from a professional trainer We recommend purchasing Larry Krohn's E-collar training book in combination with this product.
