This is the Blue Tees 3 Max plus Range Finder. Has built in magnetic for easy placement on golf cart. Toggle on/off switch for SLOPE mode. Two different color settings for target display. Lock on vibration. Original hard case is included and a charging cord. Battery lasts a really long time. I've had it for about 6-7 months now and have only needed to recharge in one time. There are no dust floaters in lens. Price is firm.
