The Cammenga G.I. Special Tritium Lensatic Compass is a military-pattern lensatic compass built for reliable navigation in extreme conditions, rated functional from -50°F to +150°F and constructed with an aluminum frame and waterproof housing. Designed for individual navigators, field personnel, and outdoor users who need accurate readings in low-light or harsh environments, it is available in Olive Drab and ships as a single unit with a carrying pouch and belt clip.
Built for Extreme Conditions
The Cammenga G.I. Special Tritium Lensatic Compass is rated shock-proof, water-proof, and sand-proof, and remains functional across a temperature range of -50°F to +150°F. That range covers arctic cold and desert heat, meaning the compass does not rely on ambient conditions to stay operational. The aluminum frame and waterproof housing provide the structural durability to withstand rough handling in the field.
Low-Light Navigation Without Batteries
Seven Tritium Micro Lights illuminate the compass dial for navigation in low-light and no-light conditions without requiring batteries or an external light source. Tritium is a self-luminous material, so the compass remains readable in darkness without any action from the user. This makes the Cammenga G.I. Special a practical choice for operations that extend past daylight hours.
Accurate Readings, Liquid-Free Dampening
The compass is equipped with a magnifying lens, a sighting wire, and dial graduations marked in both degrees and mils, supporting the precise azimuth readings that lensatic navigation requires. The copper induction dampening system slows magnet rotation without the use of liquids, eliminating the risk of bubble formation or fluid leakage that can affect liquid-filled compasses in extreme temperatures.

Who This Is For and Isn't
The Cammenga G.I. Special Tritium Lensatic Compass suits hikers, hunters, military and law enforcement personnel, and preparedness-minded buyers who need a rugged, battery-free compass that remains readable in darkness and functions reliably across extreme temperatures. It is a practical choice for anyone trained in or learning lensatic compass navigation.
This compass is subject to a hazmat restriction and cannot be shipped via air freight due to its tritium content; ground shipping only. It is also restricted for export and cannot be sold for use in some countries outside the United States. It is not suited for buyers who need a digital or GPS-assisted navigation device.
Common Questions
How does the Cammenga G.I. Special stay readable in the dark?
The Cammenga G.I. Special Tritium Lensatic Compass uses seven Tritium Micro Lights, a self-luminous material that glows continuously without batteries or an external light source. This allows the compass dial to be read in low-light and no-light conditions without any setup or activation by the user.
Why does this compass use copper induction dampening instead of liquid?
The copper induction dampening system in the Cammenga G.I. Special slows magnet rotation magnetically rather than through a liquid fill. Liquid-filled compasses can develop bubbles or leak at extreme temperatures; the liquid-free design avoids those failure points across the compass's full -50°F to +150°F operating range.
What is included with the Cammenga G.I. Special Tritium Lensatic Compass?
The Cammenga G.I. Special Tritium Lensatic Compass ships with a carrying pouch and a belt clip. No additional navigation accessories are listed as included.
Are there any shipping restrictions on this compass?
The Cammenga G.I. Special Tritium Lensatic Compass carries a hazmat restriction due to its tritium content and cannot be shipped via air freight; ground shipping only within the United States. The compass is also restricted for export and cannot be sold for use in some countries outside the U.S. Contact us before ordering if you have questions about shipping eligibility to your location.
