Increase the sensitivity of your ATTs Alarm 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 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, as shown.
Please note: If you choose the 6 magnet wheel then only the black or white options are available - you can select other colours from the drop down box, but we can only supply black or white.
