Summary: I have bought cheaper compasses at sporting goods stores for less money. The jeweled bearing is not. Jeweled bearing indicates a precise machined tolerance between the direction arrow & post. Too much slop in this compass. This description needs to be changed to indicate this slop instead.
Summary: I've had an opportunity to use this Suunto A30 Compass and it was very accurate. It appears to be a pretty sturdy plastic and not apt to break easily. Although, I'm never hard on my equipment, it seems this one will last me for many years.
Summary: Considering the price, this is a great value. This is my first oil filled compass. A real advantage. Not only in movement dampening, but it also means that it is by definition it is not effected by water. Like all precision devices, protection from shock and impact is an important consideration.
