I removed an old, redundant and u/s thru-hull depth transducer and its external fairing block when I lifted Ladybird out of the water last Autumn.
She has an internal transducer which works fine in relatively shallow waters, say <15m, but not when it gets deeper (there is oil in the tube). I have a dual range spinning LED type display and the deeper range cannot be used.
Ladybird's hull is pretty thick, @ 22mm, so should I go back to an externally mounted transducer? Would that likely increase the depth range of my sounder?
It was the thread on GPS failure and alternative navigation methods that got me thinking, ie. 'contour navigation'.
