Increase the sensitivity of your ATTs and ATTsi Alarms with these interchangeable Magnet Roller Wheels, colour matched to all the LED colours.
With the 2 Magnet Wheel the Receiver beeps once per 1 cm of line movement. With the 4 Magnet Wheel the Receiver beeps once per 0.5cm of line movement, the 6 Magnet wheel offers even more sensitivity than that.
- The ATTs is supplied with a Black 2 Magnet Wheel as standard.
- Changing the Magnet Wheels couldn’t be easier; simply unscrew the current Wheel and screw-in a new one.
