I have to agree with Ken on this one: I've installed and helped install around a dozen transducers in-hull over the years. In fact, I helped a friend do something that the company literature says you definitely shouldn't do - mount one inside a steel hull - and it worked just fine, too. In contrast to Ken's method, though, I've never used the sealed-box method - I always just epoxy the transducer right to the hull (sometimes, you have to brush/sand/grind off a clean spot, though.) The only trick is to mix the epoxy slowly so as not to introduce any air bubbles. The big advantage to doing it this way is that, while the epoxy is still wet, you can try it in several places on your hull: there doesn't seem to be any problem in shooting through that thin layer of the wet glue, and you can immediately tell whether you'll have a good signal or not. This is especially important on FGRP boats, since there might be a void (air bubble) in the hull, right under where you're planning to put your transducer. -- * Ben Okopnik * Editor-in-Chief, Linux Gazette * http://LinuxGazette.NET * _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
