Curtis, your 30 is not cored - at least below the water line. I've mounted a 
transducer in mine - under the dinette seat - all solid glass.

  I was thinking that I would need to separate them so as not to interfere with 
each other? I was thinking my C&C30 MK1 was a solid Glass bottom "Not Cored)?  
if the new transducers can see 300 feet deep can it not see forward the 25' of 
separation from one end to the other of the boat?


  Thanks

    If you have transducers working on the same frequency you will get 
crosstalk. If you have one instrument @ 50 Hz and one @ 200 Hz there should be 
no problem. 

    You can get around this by mounting the transducers very far apart, but 
apart from showing you what you just hit I don't see much point in having one 
at the stern. 

    In-hull transducers generally lose a lot of depth because the signal is 
attenuated by the hull, the thicker the hull the smaller the signal. They don't 
work at all with a cored hull unless you remove the core in that area and 
replace it with solid glass. If you can put up with limited depth, the in-hull 
installation will be easier and probably won't leak. : )

      I have a new Garmin ECho 50s 
      I would love to know how to set  the wind gauge up to the ST50 Gauge and 
the Garmin at the same time. I know it can be done . I want to keep 2 different 
depth sounders one in the New Garmin transducer and one in the older st50. One 
question on that topic? should I put the 2 depth transducers one astern and one 
forward? so I can see both ends of the boat better or keep them both just 
forward of the keel. and sense I have not purchased the Garmin transducer yet 
do I get the in-hull or the threw-hull?

        Hi Michael,

        Please post the Seatalk talk info. 

        I don't need it right now but I save these kinds of posts for when I do 
need it. 

                Cheers, Russ

          PS: I can post more information about the installation and getting the
          Seatalk NG working with ST50 instruments on Seatalk 1 if anyone is
          interested.
