Opti-Logic 400XT Laser Rangefinder Red Dot Aiming System.

The XT Series Tilt-Compensated Laser Rangefinder combines a pulsed laser rangefinder and a vertical angle sensor in a lightweight, easy-to-use package that is ideal for shooting applications that require precision distance measurements uphill or downhill. These hand-held rangefinders are capable of measuring line-of-sight distances to non-cooperative targets from 4 yards up to 1000 yards away, depending on model, target size and reflectivity. Using an internal electronic tilt sensor, the Tilt-Compensated Laser Rangefinder is also capable of automatically correcting for vertical angle with 0.1 degree resolution to provide the true horizontal distance to an uphill or downhill target. True horizontal distance is especially important for any application that require a projectile to be launched at an angle: For example, bow hunting and 3-D Archery, rifle hunting and SWAT team applications, golfing and much more.

Now with InSight feature. the InSight feature displays the range on an INTERNAL LED display, just below the red dot used for targeting. Not ONLY that, but we also continue to display the range on the EXTERNAL LCD display. So now the instrument has a dual ranging display.

All the XT models display Line of Sight in mode 1, horizontal distance in mode 2 and in mode 3, we also display Archery Ballistics, designed to take in to account arrow speeds of between about 220 to 330 FPS.

The XT series have a simple one-button operation, are powered by a single nine-volt battery, measure a minimum of four yards and have an automatic rain mode which ignores highly reflective rain drops with no compromise to the other features. They are accurate to +/- 1.5 feet.
