Is the cable used the same as other posts (Cat 7a S/FTP) ?

Sorry for asking so many questions.
I'm going to set up my Tow Fish and I can not go wrong.

Thank you.

Hi guys,

Have you made any extra sealing for the transducer cable entry (picture helps) ? How deep your towfish are swimming?

[abraquelebout]

Hi
No extra sealing for the cable entry, for moment max deep use with 100 m câble is 45 m, no problem, but it's true, the sealing seem's not strong.

I believe the transducer is potted in some type of resin. I had an older 798 that was stored in a hot garage and something that looked like resin oozed out of it. So I think it's likely safe at depth.

Also, I'm just finishing up building my own Helix 9 G2 DIY towfish. Let me know what you think:
