    "How SONAR Works"

    This could EASILY be made a sticky for so many members to use...
    Please consider it guys....
    :)
    Multiple links - but all good information!
    I hope everyone takes the time to learn MORE about the fish finders nearly everyone has - and unlock some of their unexplained "mysteries" so we all better understand what seems to happen below the ice or our boats.....

    Does anyone have a good suggestion as to which depth finder works best in shallow to mid depth weedy lakes?

    NOT exactly the best place to pose this question , but the Humminbirds have RARELY EVER lost a lock on bottom , no matter how bad the weeds are....

    All in all they are all good in shallow, the aspect is the transducer. You'll want a ducer that has a wide angle. If your angle is to narrow your field of vision is limited and you'll have to be right on top to detect a fish. The narrow ducers are generally the ducer you'll have on a trolling motor mounted unit. The lower end units will generally be a 30 or 60 degree, the next step up will be a dual beam, both the 30 and 60...good set for 5 feet to 400+fow...You can't go wrong with a HB priced in the $150-200 range

    HB seems to have one of the best for distance in shallow water.
