I compared the AltiTech 2 Altimeter against the Suunto Vector, the Kestrel 4000 Weatherstation, the Thommens 5000 altimeter, and the Garmin Etrek Vista GPS. After testing, I found the AltiTech is accurate to within 1.5 degrees in bearing, 1mB of absolute pressure (which is a little too much error, it should be within 0.5mB--and you can't recalibrate the pressure sensor, unlike the Vector and Kestrel), and 0.7 degrees F in temperature. The AltiTech resolves 1 ft increments as compared to 10 ft for the Vector; I have not tested the AltiTech's accuracy over a wide elevation range (only 550 ft in New Jersey) but I suspect it is OK if the temperature compensation works. The AltiTech's altitude and pressure graphs favorably distinguish it from the Vector. An excellent feature of the AltiTech is the altitude hold which prevents altitude wander during long rest stops. The AltiTech display is highly readable and the "button logic" is as easy (or difficult) as the Vector. Remembering the button sequences when switching between the AltiTech and Vector is an intelligence test... HighGear and Suunto could both learn from Casio. Overall, at $100, the AltiTech is a winner. Few other comments: I love my Thommens for sentimental reasons. The Kestrel qualifies me as a meteorologist. The Garmin Vista is an indispensable space age nav system for extended wilderness forays (still bring a paper map). And my Vector takes a beating (along with my hand and wrist).
