Default Furuno Bottom Discrimination

I'm seriously considering a FCV-627 for my McKee, primarily for the Bottom Discrimination featue. Determining bottom structure, such as locating oyster reefs in open bay water, could be very useful. Since I'm generally fishing in shallow water, I wondering if that feature overrides the performance of the smaller Garmin CHIRP units?

Any comments or experience with the Bottom Discrimination feature in the FCV-627 or 587?

Thanks.

Ken

I have the 587, love it, but used the bottom discrimination once and it is a gimmick and a waste of time. Just takes up screen space. Learn to understand what the picture is telling you as the picture is pretty good!

This feature is not a gimmick if you use the correct transducer and understand the operation. It works quite well from about 16' to 300'. Keep in mind that it is not to be used when targeting fish. When you want fish targets you turn it off.

While you will mark fish with bd on, it is pinging both hi/low to work the algorithm needed for bd. I was told you will get better fish detection when it is off. Next time out on my buddies boat I will have to play and see what the difference shows.
I do know some crab and lobster guys in the keys and bd is important for trap sets.

I have run a good many tests using the BD feature and being old school still prefer the traditional method of determining bottom hardness.
And it is my opinion using BD does not diminish target detection capability while on.

However......many of the fish I caught did complain of blurred vision and a ringing sensation in their heads while the BD feature was in use
