Thanks for the info. on Simrad. Interesting, however does not appear to give me the information I am looking for. It will indicate that a target is out in front somewhere, but does not indicate where. I want to know where that target is with relation to the front of the boat. Distance, right, left, or center! What is the azimuth, heading, of it. I need to be able to see the channel, holes, and shallows ahead of me, and know the location, not just that there is something somewhere out front. Also it appears that this one works with charts. There are none in some of the areas. From reading their information, it appears they basically took the transducer and pointed it forward, instead of down. Also in the installation, it is mounted protruding out the bottom of the hull. Not acceptable. ==== Maybe I missed something, but still looking Thx
