OPERATION
Depth Scales
In Normal Mode, read the outer white scale and multiply by the range setting. Here, the range is set to “x1.” Bottom is at 15 feet, a sh is at 12
feet, and there is a weak signal at 10 feet. If the Range Control was set to “x2,” the bottom would be interpreted as 30 feet, the sh at 24
feet, and the green mark at 20 feet.
Mode Control
(Normal Mode selected)

Range Setting
The FL-18 has ve depth ranges. Zero to 20', 40', 60',
80', and 200'. To interpret depth, you multiply the
displayed reading by the range multiplier.
