I'd love to map out my home course I play at cause it has a lot of elevated tee's on the par 3's. Thanks Ralph Ralph You have the right idea, but if you have a 10% uphill slope you better get a 4 wheel drive/////. Most slopes are from 1 to 3%. There are exceptions of course, there is a par 3 at San Diego that plays 14% downhill. The yardage is about 180 but it plays 17 yds less. Back to your question; a clinometer is not hard to use once you become comfortable with it. However, it is a hand held tool and like a compass it takes time to learn how to use it properly. For the first while it will take you some time to get a proper reading; a minute or two; however you will quickly get the hang of it and your time will quickly drop off. A reading takes me about 3 seconds. If you want to be really accurate, here is the formula that is built into the Lazer chip. The need for this is because of the traj. of the ball. For 0 to 100yds, use 50% of the percentage (uphill or down) For 100 to 140 use 75% of the percentage For shots over 140 yards use 100% Hope this helps.
