Bottom Detector
The Bottom Detector dialogue box is opened when you
right-click on the numeric depth value in the Header view on
the display.
This dialogue box is used to define the upper and lower depth
limits most likely to be used during the echo sounder operation.
These limits may be used to obtain ”bottom lock” on the depth
when the echo sounder is pinging. The sounder needs this lock
to locate the correct depth, and to stay on it during the
operation, even though the depth changes continuously.
The dialogue box is also used to set alarms to notify you if
maximum or minimum depths are exceeded.
Parameters
Minimum Depth - The bottom detector starts the search for the
bottom echo at this depth. The detector will fail in shallow
water if you select a too large depth value, and the tail of the
transmitting pulse may cause problems if a too small value is
set.
