Have first bought in 2013 a Scorzähler for pants / jacket pocket. That was a plastic box slightly smaller than a normal matchbox, with two pushers and Zählrädern. This unit was so poorly handled that bent the handle after a few laps and the plastic mechanism failed. Press once they added either no impact or equal to two or three. The ten-euro for gadgets from the pro shop I have thrown away in anger. Therefore, no exchange possible. "Device in the Off", you might say. When acquaintances I saw this og Score wheel. I found the mechanism apparently simple and display appealing. To say it first: I use the counter yet. He hangs on the golf bag. But he's not really perfect. Reason: Some wheels go so heavy that it hurts the finger. Other wheels tend to totter just by moving the trolley. While there is not yet such an extent that one does not see the error in a score of control, but that's annoying: A "penalty stroke" for the golfers, because he uses a so imprecise part? That's unfair! Actually this display system class: At a glance I can see the individual results for 18 holes. Why is it not possible to put together such a meter of better components and precise, is told honestly a mystery. I would spend on a functioning, finger friendly device also 15 to 20 euros. But apparently, the market for manual score counter is so small that no one has come up with this idea. If someone has identified an efficient, trouble-free system, I am pleased with a comment related notice.
