Having a few dramas with my sounder in deep water and wondering if anyone has experienced the same thing.
This will be a bit long winded but I'll explain everything.
I have a furuno 587 with a 1kw airmar tm260 transducer
And a lowrance hds7 with the standard transducer.
In shallow water, and when underway my 587 holds bottom fine,
But as soon as we stop in deep water, the 587 looses bottom, becomes very patchy and won't mark any fish or bait,
So it won't hold bottom or mark Bait when drifting,
Originally the tm260 was on the wrong angle, ( fitted by dealer!! ) so we removed it, and replaced it within the airmar specs, tested it again, same problem,
A few calls to furuno, a few settings changed, re tested and the same problem.
Furuno then sent me out a p66 to test, we fitted the p66 and headed back out the shelf, same problem
So a call to Barcrusher and where my tm260 is positioned is where they mount there's, but I'm using different trim tabs. They said they have mounted hundreds and never had this problem.
Also my lowrance transducer is in the same spot on the opposite side and does not have this problem!! The lowrance hammers as you will see in the pics it works great!!
Both sounders are run on full manual and all transducers are linked to the sounders correctly
I now have both transducers removed and they have asked me to drive back out the shelf, and hold the transducer over the side of the boat - taking away any possible interference from the engine/ trim tabs ect.
I've tried turning the motor off, turning the other sounder off ect ect
Has anyone ever seen anything like this before?? Or have any idea what could be causing this to happen?
The furuno techie said it's very uncommon to loose picture when drifiting, but I can travel in 1.5m sea at 20 knots and not loose bottom.
Cheers Matt.
