has anyone used this is it just another con

oh please!!!!!

if this device requires 3 dimples to be visible by the device at 35ft them I'm damned sure that I could see the ball with my own eyes.

£142???????????

please let me lie down and be mugged.

lol

Well, it wont be legal for competition usage when you would really want to find your ball.
For the price you can buy a lot of golf balls.
Intuitively it seems hard to believe it would actually work in any really useful way.

Definitely a useless gimmick gadget.

£142 = 63 Titleist Pro V1's,

thats a lot of lost balls before its gets near to paying for itself.

I would like to have a go of one to see if it works though.

63 V1's? So thats less than a month..................

2 rounds for me ; )

Or potentially a shed load of saved penalty strokes.
