The BOTTOM FINDER UPGRADE gives your
OFFSHORE HUNTER Plotting Screen the
THIRD DIMENSION: DEPTH
Choose your BOTTOM FINDER volume based on the areas you fish.
(Note: OFFSHORE HUNTER covers the
entire coastal US and Great Lakes waters.)
Six BOTTOM FINDER Volumes cover Texas to Maine
Operation of BOTTOM FINDER requires OFFSHORE HUNTER software.
BOTTOM FINDER calculates the depth of the area shown in the plotting screen; divides the range by twelve; then assigns each of the depth range a color.
For example, if your selected plotting area is 30 to 150 feet, then each color would represent a ten foot increment. Zooming in the Plot Screen might take the total depth range from 100 to 110 feet. Each color would then represent on foot of depth. In this case, if three or four colors run together, it indicates a 3-4 foot ledge or drop off.
