Construction Forum Fraction Calculator App

I've been using this for work for a few months now and it's been working great. I set a programmable key for the calculator app which I use frequently. With use of 8 - 10 hours a day the batteries have not needed to be changed. The mechanical keys are much more accurate that the standard I've been used to using. Much easier to type on.

Has a very high-quality construction look. The sliver color makes it readily obvious when mounted on the lens. The fraction of a millimeter over the OD my Nikon 24-70 zoom requires a little practice to put hood on when mounted.

Amazing quality sound and construction at a fraction of the cost of the nearest competing product. The design is so perfect, it has remained unchanged for nearly 20 years. My first pair finally broke out after about 11 years and a lot of very hard use. The old speakers still worked, but they had been dropped so many times, it was too much for the housing. Not even tape could hold them together. If you drop then from chest height onto a solid floor or table, that will most likely crack the shell or puncture the ear cover. But they will work just fine. Just treat them well, they should last a lifetime.

This lens is incredible, and at a fraction of the cost of the top equivalents. The sturdy construction is perfect for the higher level SLRs, and the output is amazing. I've only begun to use the lens, but the pictures are wonderful with minimal, if any, barrel distortion. Hats off to the manufacturer for such a well-designed and useful addition. One additional point, the focus chip makes for easy use of the lens for P, S, and A priorities.

The 10 stop filter is simple to use with the long exposure calculator.

Photography in a dark room. Love the calculator being available at all times

lots of space, heavy duty, and easy to forum to what you need it too

does what you need at a fraction of the price of others.

This calculator is beautiful, stylish and perfect. Item exceeded my expectations. I would purchase again.

The battery is for an older calculator. Back of the calculator indicated a different battery. After opening the calculator took the old battery out and the new one from B&H in it's place. Simple fix.
