Bresser's bow-mounted laser rangefinder works with a compound bow or cross bow's existing sight/scope to provide archer's the accuracy that can truly make a difference in the field or at the range.This lightweight rangefinder can be easily mounted on most modern compound bows and crossbows and has three axes of adjustment for proper positioning. It can accurately measure reflective targets up to 100 yards and show those calculations on an OLED display that can be easily read without disengaging the bow. As an added benefit, it has a scan mode that is constantly active to keep you fully aware of distances to potential targets. Accessories include a lens cleaning cloth and a microfiber bag for transport and storage.
