Rangefinders have a very distinct mechanism when it comes to measuring the distance in a golf course. Bushnell Pinseeker 1500 Tournament Edition is one such device which uses a very easy yet accurate mechanism to give you the exact distance of the target. It is very simple to use this rangefinder. You just need to point the laser to the object and click. With this action, the Pinseeker will send out a pulse of light to the object. Then it will take the amount of time the light takes to bounce off the target and return. It keeps the speed of light as constant and then uses simple math to calculate the distance. This simple mechanism helps you to get a very accurate measurement which in turn lets you hit your shots more accurately.
