Alan, Rain and wind noise over-power transducers in 6000 fsw that have great DSP units backing them up. So your point of suspending it deeper doesn’t apply. Plus croakers are bottom fish. To get 70 fsw off of Ft. Pierce you have to go 10 miles offshore. 40 miles south, you get this much water within a mile of shore. If we get a barge, I expect operating depths to be 35 fsw.

Thanks for reminding me David. This is what I was getting at originally when I gave examples of operational variations of similar products on the market. Also the above post gives weight to my suggestion that if you hung the boat unit lower in the water further away from the surface noice, you may find you hear better despite the proliferation of croaking fish in your waters. If you're experimenting with this unit at the conferance why not take an extra 50ft of wire & test this out. Kind regards Alan |
