The Martin System Chameleon 4 set is a two-way remote training e-collar kit: the Chameleon IV collar, the CTT 4 remote and the hands-free Finger Kick, for handlers in IGP, obedience and working-dog training.
Because the collar reports back to the remote, you can check contact, collar temperature, battery and signal quality while you train, so you know the dog is actually receiving what you send.
- Two-way system: collar data shown on the CTT 4's backlit colour screen within about 100 m
- Range up to 1,000 m; one or two collars on one CTT 4
- 18 stimulation levels, 2 to 4 buttons per dog, rising and decreasing modes
- Chameleon IV keeps all the Chameleon III B features; waterproof collar and remote
- Collar sleep mode by distance, rotary button lock, adjustable or switch-off backlight
- Wireless fast charging or cable charging for both remote and collar
- Patented Finger Kick for wireless, hands-free stimulation (within 25 m of the remote)
Use: competition and sport training where hands-free, discreet control matters, and for handlers who want live feedback from the collar. Martin System e-collars are used by UK military dog units, including special forces dog teams. Collar sizes and the full manufacturer details follow below.
This set pairs the Martin System Chameleon IV collar with the CTT 4 (Chameleon Tactical Transmitter 4) remote and the Finger Kick. It's a two-way system: the collar sends information back to the remote, so you can see what's happening at the dog's end.
Collar sizes
- Large: 33 cm (13 in)
- Medium: 26 cm (10 in)
- Small: 20 cm (8 in)
Chameleon IV collar
The Chameleon IV keeps all the features of the Chameleon III B. It's discreet and comfortable, and the contact points can easily be moved. It's waterproof and charges wirelessly or by cable. Much of its technology is patented by Martin System.
CTT 4 remote
The CTT 4 has a backlit colour display that shows the information sent back from the collar. Within about 100 m it displays:
- Contact measurement
- Collar temperature (°C or °F)
- Battery level
- Radio signal quality
A rotary button lock stops the stimulation level changing by accident. The screen brightness can be adjusted, or the backlight switched off, for discreet training.
Finger Kick
The patented Finger Kick pairs with your remote and lets you trigger the stimulation button wirelessly, hands-free.
Battery saving and charging
- Collar sleep mode by distance, using the CTT 4, to save battery when you're not training
- Remote and collar charge wirelessly (fast charger) or by cable
Doggify app
The free Doggify app shows contact measurement, collar temperature and battery levels for both collar and remote. You can also set the feedback refresh rate, alerts on the CTT 4, stimulation levels and more.
FREE insured delivery included – sent by Royal Mail Special Delivery Guaranteed (next working day by 1pm once dispatched), fully insured and signed for. Northern Ireland orders: £3 NI postage paperwork charge.

Frequently asked questions
What's the difference between the Chameleon 4 and the Chameleon III B?
The Chameleon IV keeps all the Chameleon III B features and adds a two-way link to the CTT 4 remote. The collar sends contact measurement, collar temperature, battery level and radio signal quality back to the remote's backlit colour screen.
What does the Finger Kick do?
The Finger Kick pairs with the remote and triggers its stimulation button wirelessly, so your hands stay free. It works within up to 25 m of the remote and isn't rechargeable. A CTT remote takes up to 4 Finger Kicks.

How do the collar and remote charge?
Both the CTT 4 and the Chameleon IV charge with the wireless fast charger or by cable. The collar also has a sleep mode by distance, which works only with the CTT 4.
Does it work with the Doggify app?
Yes. The free Doggify app shows contact, temperature and battery for both collar and remote. You can also set the feedback refresh rate, the alarm on the CTT 4 and the collar stimulation levels.
How quick is delivery, and can I return it?
Order by 2pm Monday to Friday and we dispatch the same day. E-collars come with free insured next-day delivery. You can cancel within 14 days of receiving your order. For hygiene reasons, an e-collar supplied sealed can't be returned once the seal is broken unless it's faulty, so check the model before opening it.

Manual and troubleshooting
Martin System Micro IV / CTT 4 user guide (covers the CTT 4 remote) (PDF, opens in a new tab) · Martin System Finger Kick user guide (PDF, opens in a new tab)
- On/off: any button wakes the CTT 4, and turning the knob below 0 switches it off. Switching the CTT 4 off puts paired collars to sleep and switching it on wakes them, but the wake-up range is shorter than normal range (CTT 4 guide pp. 16-18).
- Level won't change: the knob is locked. Hold the program button and turn the knob at least 5 clicks to lock or unlock it. You must unlock it before you can switch off normally (p. 25).
- Charging: the green battery icon flashes while charging and stays on when full, and Martin System says you can't overcharge it (p. 30).
- Test lamp doesn't light above level 1: check in Doggify that stimulation is turned on. A faint blink during the contact check is normal (p. 31).
- Chameleon IV collar: Martin System's FAQ says charging and unpairing work the same way as on the Chameleon III B, so see the Chameleon III B guide.
- Wear: the collar is waterproof. Martin System says never more than 8 hours in a row, and check the skin under the contact points every day (Chameleon III B guide p. 17).
