Abstract
A handheld rangefinder device operable to determine ballistic hold over information is disclosed. The rangefinder device generally includes a range sensor operable to determine a first range to a target, a tilt sensor operable to determine an angle to the target relative to the device, and a computing element, coupled with the range sensor and the tilt sensor, operable to determine a hold over value based on the first range and the determined angle. Such a configuration facilitates accurate firearm and bow use by providing ranges and hold over values without requiring time-consuming and manual user calculations.
