The Bottom Detection Menu; Minimum Depth - Simrad EY500 Instruction Manual

2.6 THE BOTTOM DETECTION MENU

The Bottom Detection Menu contains choices for setting up the range of the
bottom detection algorithm and minimum and maximum depth. It also contains
choices for alarm settings and value for minimum bottom echo level. Refer to
paragraph BOTTOM DETECTION in section "Theory of Operation". Setting
minimum and maximum depths to 0 will disable the bottom detector and will
be important when pinging horizontally. Layers should then be of pelagic type
since the latter do not require bottom depth detection.

Minimum depth for the bottom detection algorithm.
The bottom detector algorithm uses the minimum and
maximum depth settings to limit the range of interest for
finding the real bottom. Very often the default values
will not correspond with the presumed depth pattern in
the area of surveying. Therefore, to speed up
computations, you may enter the best values according
to the expected depth.
