More than 6 0 years af ter it s original design as specif ied by the U.S. Army, the Cammenga 3H is also known as the M1950 compass, which began produc tion in 1950. It ’s been relied upon by generations of soldiers through all environment s , including the frozen Chosin Reser voir in Korea , the jungles of Vietnam, and presentday ser vice in Iraq and Afghanis tan .
It took it s design cues from lessons learned with the M 1938 compass used in W WII . The Army liked the basic blueprint but wanted to give it a tougher and heavier housing as well as a damping mechanism to prevent wild swinging of the needle. With these modifications , a legend was born .
Like the Brunton model, the 3H is made in the United States and uses a non-liquid filled needle housing. The movement of the needle is ver y smooth , although it doesn’t turn or set tle in quite the same confident or reassuring manner as the Brunton. We liked that we were able to open and use the compass using our whole hand , not jus t our f inger tips as with the larger Br unton . Op ening and sighting was fas ter and more intuitive, and the seven tritium micro -light s as sis te d in low -light a cquisitio n .
From a durabilit y s tandpoint, there’s no ques tion that the
3H is hard to kill. It ’s waterproof and shockproof, and tes ted in temperatures from -50F to 150F (-45C to 6 5C). The aluminum frame, although not quite as tank-like as the Br unton Transit, is s till subs tantial and didn’t have a problem with being dropped or s tepped on .
Even in 20 18, any combat veteran who has ac tually had to rely on his or her gear will tell you that some of the Mil- sp ec ar ticles they ’re is sued are complete junk . With a s terling track record and a more than half- centur y of abusive f ield tes ting behind it, the 3H is a well-loved exception . We wouldn’t hesitate to place our lives in it s hands , and there aren’t many sub $ 10 0 tools we can say that about . Published accurac y : +/- 2 . 25 degrees .
