Changing transducer in water

[Briankinley2004]

I think you can get a garmin version and change it out. I cant check until tuesday.

Thats fine. I don't really need temp. Out here in the gulf its usually way different from surface at 20' anyway. comes in handy diving to know what you are jumping in to. If it can be changed out will definitely do it but its no rush. Im good for my fishing trip now

I know there's a difference in raymarine temp and furuno that's not able to be wired around. One has a capacitor to the outer metal housing and it makes wiring different. I forget which it was. I have used a ray b774v ducer on garmin 7610 screens but I think it was a different connector than your gsm24.

A few more beers and I'll make up a story and swear to it.

A few more beers and Im gonna hang a thermometer on a string over the gunnels. Same results and no network required
