Raymarine A65 Transeducer.

[Norv]

Hi all, A little advice from the more knowledgeable,
I have a Raymarine A65 plotter connected to a DSM25 and a speed depth Temp transducer. Sadly as this was mounted over the side I lost it ripped the cable out of the DSM 25.

So I am left with the DSM 25, As the boat is now out of the water I wanted to fit a thru-hull transducer, What is the best or most compatible Speed Depth Temp Transducer to fit to the A65 system?

I only find external fitted ones

Thanks for any time given

Regards
