SILVA Micro Racer Mapboard Compass with detachable mapboard clip
A versatile combination of a SILVA Micro Racer thumb compass with a removable polycarbonate mapboard compass holder developed by Windchill Sports.
You can use the thumb compass in the holder as a Mapboard compass, or remove it from the holder to use it as a thumb compass.
* Please note that the Micro Racer compass has a tendency to develop a small bubble which does not affect it's function. The bubble will usually dissipate when the compass is warmed, such as leaving it in the sun.
