Airmar In hull transducers - 600 Watts

[peterb]

I have a Garmin 178C GPS/FF. It will serve as both the backup GPS and FF on my new boat.

I already have one thru-hull installed for the primary FF (a raymarine DS600X) and an unused seacock near it. I plan to use that for either a live well and/or stal water washdown.

I don't want another hole drilled into the bottom of my hull.

This leaves me with either a transom mount or in hull. I would rather not go the transom mount. By default this leads me to the in hull solution.

I see the cheapo 600 watt solution or the expensive 1,000 watt solution. I have read great things about the 1k unit, but is seems a little pricey for me right now for me (at least $600).

Has anyone ever installed the 600 watt in hull in a SeaCraft, and if so, what has your expeience been?
