Filter Adapter (AD301R)-DISCONTINUED

Bought this for reading maps at night without wrecking my night vision, and it does exactly that. The red tint is strong enough that I can still make out trails and grid lines, and it clips on in a second.

The anti-roll design actually works, I've knocked it off the table twice and it stayed put on the map table. Reading grid coordinates by red light keeps my night vision intact instead of blinding myself with a white beam. Solid little piece of kit.

Didn't realize how much a red filter helps until I tried this on a night hike — maps stay readable without killing my night vision. The anti-roll design is a nice touch too, it doesn't wobble around when I set it down.
