The Vendetta 2 will increase your success in the field. It can be mounted to a compound bow or a crossbow to give you an instant and precise digital readout of your angle compensated range to target, with no excessive movement or noise. Push the trigger pad for an instant reading, or hold the trigger for three seconds then release to begin a 40-second scan mode which continually adjusts distance, angles and elevation as your target moves. It is completely weatherproof, and will withstand any prolonged rain or snow storm. It includes a scope adapter for a 1" diameter maintube.
