The Gardner Tackle ATTs Bite Alarm 4 Magnet Replacement Rollers give you the ability to change the roller colour and sensitivity of your Gardner ATTs Bite Alarm.
They come in a wide range of colors that match all available LED colors, and more.
Different roller wheels different sensitivity.
As a guide, this means: With wheel 2 Magnet the receiver beeps every 1 cm of line movement.
With the 4 wheel Magnet receiver sounds every 0.5cm of line movement .
With the 6 wheel Magnet receiver sounds every 0.33 cm of line movement.
To replace the wheel, simply remove the roller pin, swap the wheel, and replace the retaining pin by screwing it onto the integral thread. (Click the video tab below to watch a short instructional video for replacing the rollers.)
