Callaway CSI Pro Laser Rangefinder delivers all the distance measurement features golfers require to maximize their game, enhanced by a unique new feature called Club Selection Information (CSI). The CSI golf laser works as your own personal caddie, making club suggestions based on your average 7-iron distance which you plug into the unit. The Callaway CSI Pro laser is lighter and more compact than other lasers and offers 6x magnification with a 1000 yard range and superior +/- 1 yard accuracy. The CSI Pro also features P.A.T. (Pin Acquisition) with Pulse Technology™ which delivers a short vibrating “burst” confirming the correct distance to the pin, giving you the confidence to fire away! The CSI Pro also includes Magnahold, a powerful integrated magnet that allows you to securely affix the unit to the cart frame for quick and convenient access during play. In Slope mode the laser will automatically account for adjusted distances due to elevation changes, and comes with an external on/off switch that can be easily disabled for (legal) tournament play. The CSI Laser is water and fog resistent and is backed by a 1 year limited warranty, and includes premium carry case and cleaning cloth. Whether you’re trying to pick the right club to carry that fairway bunker, or aiming directly at the flagstick of an elevated green, you'll now be able to take dead aim with confidence with the Callaway CSI Pro Laser Rangefinder!
