Furuno network sounder tweaking
I'm looking for some tips in tweaking my Furuno sounder. I use a DFF-1 sounder module that's networked to the VX2 system. The sounder uses a B744 transducer, that's the airmar model, I'm not sure what the corresponding Furuno model is, but it's a bronze 50/200 hz 600W with temp and paddlewheel speed. I've never had much success getting it to read beyond about 200 ft, I've been going through the Furuno manual with not much success. For me, the Furuno manuals are abysmal for instruction, just the worst. They're great for headaches, but that's another issue.
Anyone have some tips on how to get it reading deeper? I know it has limitations, Airmar says 1200 ft @ 50hz, 700 ft @ 200 hz. I've been trying different settings (noise, signal, freq, gain, etc) but can't hit a combination that will get it to read deep water, and there's plenty of it here in the Bahamas! Maybe I'm just expecting too much.
Now I know it really doesn't make much difference if it's 60, 600, or 60,000 ft deep, I'm not gonna hit bottom. But that's not the point. The point is getting it to do what it's supposed to do. BTW, the transducer is less than a year old. (and the speed doesn't work, never had one that worked for more than a few months, just expect it not to, IMO they're crap)
Suggestions?
