The DG1 Plus is Dallas Golf's very own laser rangefinder. It's an alternative to the base model rangefinders on the market from Leupold, Bushnell, and others. It has 6x magnification, is precise to 1 meter, has a maximum range of 600 meters, and is water-resistant enough to use in the rain. It functions in either yards or meters. Your choice. We're including a 3V (CR2) battery - good for 10,000 actuations - at no extra charge. There is also a durable pouch with velcro closure, a small cleaning cloth, and a clip to hang it on your golf bag. The DG1 Plus laser rangefinder unit has a fog mode (in case you need it), a flagstick lock mode, and even a slope correction mode. All things that you generally find with rangefinders that are nearly triple the price! Included is a simple set of operating instructions so you'll be on the course ready to go in no time. Warranty is 1 year - provided by Dallas Golf. Satisfaction guaranteed.
