I'm wondering what folks are using for Depth Sounders. My 25 had a Hawkeye that the previous owner tore out in frustration, and I have been careful to sail in charted waters, but really need to get something installed since I have a nasty little Channel to get to open water (Joe probably knows the Bristol Narrows well!).Anyway, after a little research, all of the small in dash units, like the Hawkeye and Hummingbirds seem to have problems with the gauges giving up after a season or two. My research seems to point to the LOWRANCE M68C, which combines a depth/fish finder and GPS, for about $400, which is about my limit for a depth sounder, but with the added bonus of GPS. Also, I was planning to install the transducer in the hull, amidships. Anyone have any problems with that type of set up? I'm not real crazy about doing a transom mount and would rather not put another hole in the hull.Any suggestions would be appreciated since I know most sailing magazines are not apt to criticize advertisers, so unbiased opinions are welcomed.
