Rangefinders assist the hunter in finding prey.
Hunters will find Brunton Rangefinders quite easy to operate, with both the Lytespeed 400 and the Laser 70 units offering a great advantage in accurately centering on prey and calculating its distance. Both rangefinders emit an invisible, eye-safe laser energy pulse that reflects off the hunter's target back to the unit's receiving optics. The rangefinders can instantly calculate distances between hunter and prey by measuring the time it takes for each pulse to travel from the unit to the target and back.
Instructions
1. Check the battery of the rangefinder and the temperature of the outdoors first. Both units need a single 9-volt alkaline battery. It will operate the Laser 70 for about 10 hours or 500 shots at an optimum temperature range between 32 degrees and 104 degrees Fahrenheit. The Lytespeed 400 battery life is around 300 hours. The difference is that the latter unit is programmed to shut itself off after 30 seconds if no buttons are touched.
2. Raise the monocular eyepiece to your eye. The Lytespeed has a hard rubber border that can be rolled down to accommodate hunters wearing glasses. Sight through the eyepiece, centering the target in the crosshairs located in the middle of the viewfinder.
3. Press the large round button found on the top right side of the unit to fire the laser, once the target is in the center of the small square in the crosshairs. Read the distance to the target in the bottom of the viewfinder in large numbers.
