The Str8 compass has a few features that stand out: - An adjustable thumb angle. Ever had to worry about whether your direction arrow was pointing straight ahead of you? The Str8 compass has three different angle settings for your thumb strap to avoid that problem - An anti-slip map gripper on the base of the thumb plate - A 95 mm direction line that runs right through the compass module
This new magnifier is designed specifically to fit with the Str8 compass. It attaches to the compass using the thumb strap and has the same adjustable angle (plus or minus 20 degrees) that the Str8 thumb compass has. Comes with a strong, lightweight aluminum frame for more durability.
