First I had to deal with the ridicule of the other golfers in my foursome. Walking around a golf course with a radar detector isn't exactly a common sight, and when I thought I'd finally found my ball, the machine turned out to be beeping at the spare one I keep in my front pocket. Yeah, har de har har. But the real issue lies with the information the detector provides. You get a â€you're getting hotter/colderâ€ sort of feedback, so you need to know generally where your ball has landed and then walk around until the beeps get stronger. Not much different, in other words, from what you usually do when searching for golf balls. On two occasions my golf partner found the ball quicker than the machine did, and it wasn't even beeping.
