Lumonite Hackrings

In Stock

Lumonite Hackrings are perfect sized O-rings that enable attaching Lumonite Compass R to the Lumonite UL-, UL2 or Ergo headband.

The adapter O-rings were specially designed for professional orienteering use, to make carrying of the spare lamp extremely easy. Thanks to the O-rings, the spare lamp can be always aimed to the right direction. This makes switching to the spare lamp very quick and easy. With this product, using Compass or Compass R as a special lamp for reading the map is also possible.

The O-rings center the spare lamp body inside the tube of headband, making the aiming perfectly accurate and stiff.
