[Public-List] Internal mounting of depth sounder??

[Gordon Laco]

Hello Michael,

My own opinion is that a depth sounder without a navigation chart is useless.  The depth reading can be correlated with charted depths to help determine position… and THAT is what lowers the chances of going aground.   Probably the most useful application of a depth sounder is when dropping the hook and determining how much anchor chain or rope needs to be let go.

Two months till sailing… wahoo…
