Overview
This Cammenga 3H is the official US military lensatic compass, illuminated by 7 tritium micro lights rated to glow for over 12 years, built for shockproof, waterproof and sandproof navigation from -50F to 150F.
Unlike the phosphorescent Cammenga model in this same list, this one uses self-powered tritium lighting, so it keeps glowing without any light exposure or battery, which is the main reason it costs more than a standard lensatic compass. It ships as a kit with a pouch, lanyard, instructions and storage case rather than as the compass alone.
- 7 self-powered tritium micro lights
- Lensatic sighting system, US military grade
- Operating range -50F to 150F
- Includes pouch, lanyard, case and manual
Who it's for
Suited to military, tactical and serious backcountry users who want always-on night illumination and a full accessory kit. Casual day hikers who never navigate after dark do not need the tritium feature and could get by with the phosphorescent version instead.
Pros and cons
- Tritium lights glow continuously for years, no charging needed
- Full kit: pouch, lanyard, instructions, storage case
- Rated across a -50F to 150F operating range
- Shockproof, waterproof and sandproof build
- Costs more than Cammenga's phosphorescent lensatic model for the same daytime accuracy
- Lensatic sighting has a learning curve for first-time users
Performance notes
The 7 tritium micro lights are self-powered radioluminescent lights rather than glow-in-the-dark paint, so they keep emitting light continuously for years without needing to be charged by a flashlight or sunlight first, rated by the maker at over 12 years. The lensatic sighting system and reinforced housing are built to the same rugged military specification, rated across a -50F to 150F range, and the kit includes a pouch, lanyard, warranty card, instruction booklet and clam shell case.
