The Golf Scientist

Here is my Opinion on these 4 rangefinders

The Callaway 300 Pro is $178.13 the Callaway 350TL is $299.99
Callaway EZ Rangefinder is $267.64 and the Tour-S is $401.68 right now the features is it clips onto a golf cart by a string magnet, and it has Pulse technology. That the Device delivers a short vibration to confirm the laser has locked onto the pin, and it comes with a case, and it has three modes, and it comes with batteries, and it has a video on all four models you can look at it to decide which one is your favorite I recommend the Callaway 300 Pro.
