[CA] [CA11] In hull transducer/ instrument recommendation

[nscott54]

For 6 years I have been successfully receiving depth info from my i40 depth display linked to a 2003 vintage b744v throughull transducer. These have performed flawlessly with the rest of my St instruments (RL80c plotter, ST60 multi displays)

Today the i40 stopped receiving data - showing “- - -“ only for depth.
I presume the issue lies with the transducer.

Having just had the boat hauled for service and maintenance I am loathe to have her hauled yet again to replace the transducer.

What are your recommendations for either:
a) A new in-hull transducer that would be compatible with the i40 depth
Or, if this is not possible,
b) a new in-hull transducer and new depth display that would be compatible with my existing St instruments

Thanks,

Neil Scott
