Fairey Mary

Mary has a transducer fitter into a pipe bounded end on to the inside of the hull.  The pipe is full of linseed oil I believe, which the transducer sits in.

But she has the old NASA with the sweeping display and LEDs giving echo strength.  I believe the results are meaningful and I would love to say I haven’t hit the bottom yet.  But there are those amongst us that know that would  be a lie.
