Don't bother with the Arccos Senors. The concept is great, but the execution is so problematic that I can't use it as part of my game. you are better off manually tracking your shots. i have had 7 sensors fail in the last year. Arccos' response to a failed sensor is to (1) ask you to send the failed sensor back first and (2) they will mail out the replacement. the problem with this is, that if your Putter sensor fails, the Arccos software will no longer let you track your shots. Don't know why you need the putter sensor to work to see how far your driver goes, my only answer to that is it is some sort of license enforcement policy from Arccos. I have been an engineer and manager in the field of industrial electronics for the past 33 years, so I know what I am talking about. I found that I was more distracted by fiddling with making the sensors work than I was on my game. BOTTOM LINE - DON'T BOTHER. THE PRODUCT FUNCTIONALITY IS SO INCONSISTENT THAT IT FURTHER FRUSTRATES YOUR GAME.
