Ranging Modes

Horizontal Component Distance (HCD): Displays the slope angle compensated distance to the target.

Ballistics (BAL): Displays the actual line of sight range and wind/drop solution.

Scan Feature: Displays continuous distance readings while panning across a landscape.

Target Modes

Normal Mode: The standard mode providing the target's range with the strongest range result. Recommended for most situations.

First Mode: Displays the closest distance when ranging. Ideal for ranging a smaller target in front of other larger or more reflective objects.

Last Mode: Displays the farthest distance when ranging. Ideal for ranging a specific target behind a group of objects like brush, trees, rocks, etc.
