We have a good selection of Rangefinders with Hypsometers from top brands such as Opti-Logic and Laser Technology. What's a hypsometer and why might you need one when measuring distance? Well, a hypsometer allows you to measure height or altitude of an object. You would want to be able to do this in order to adjust for elevation when taking a shot while hunting or hitting a golf ball to the green. If you're aiming uphill you'll need to adjust to make the proper adjustment. You'll likely need a stronger club to hit a green at the top of a hill, and if the hole is downhill you'll need to make a similar adjustment to a lower club. Laser rangefinders/hydrometers make your distance measurements more accurate and useful for precise shots. Play at your best with the most information before you line up a shot by outfitting yourself with a rangefinder with a built-in hypsometer.
