Customer Q & A

1 Question About This Product
Q: "Are there any instructions as to how to use Barska's rangefinder reticle?"
A: The verticle scale (reticle) visible through the left half of the binocular, above the compass display, allows you to calculate distance to an object if you know its height, or to calculate the height of an object if you know its distance from you. Each mark on the verticle scale has a value of 5 MIL (1MIL is equivalent to an angle that can determine an object one meter in height at a distance of 1000 meters). Therefore, if a navigation chart gives the height of an object, by sighting on it and counting the number of MIL's, you can determine how far away it is. Here are two formulas: To measure distance when the height is known: Objective Height (m) ý Scale Reading X 1000m = Distance in Meters To measure object height when the distance is known: Distance (m) X Scale Reading ý 1000 = Object Height in Meters
