TRIG, a function that is included to support tradesmen and
sportsmen, displays the true horizontal range and true vertical
range, which is based upon trigonometry using angle and line
of sight distance . Line of sight distance (LOS) readings will be
displayed in the upper portion of the display . The lower display will
briefly show the true horizontal distance (cosine) then the absolute
value of the true vertical distance (sine) . Have you ever wondered
if that leaning tree would hit your home or tent if it fell? Measure
the height by obtaining the true vertical distance and then
measure the distance from your house or tent to the tree .
