Image is taken with boat at rest. Transducer has simrad structure scan transducer immediately adjacent and below but i think this is ok?



Simrad nss7 manual not much good here. Any advice appreciated.

Yeah done that already, before posting, also found a few posts that you previously commented on re air bubble interference. I have been under boat at rest and there are no air bubbles.....Can't find any previous posts with diagrams, schematics, etc, or much on electrical interference. I was hoping someone might recognize the interference pattern and provide me with some guidance... for what is worth, interference pattern seems constant even with rerouted cables...so is this a duff transducer?

Thanks kaveman...Yeah placement is not ideal....but there are planing strakes i had to avoid nearer the centreline...Will try fiddling with settings more and see if i can post a downview and fishfinder on same screen next time I'm out, add suggested. Ta.

strakes are a major concern to get good readings.  With sideview, your transducer  needs to be as close to centreline as possible. Also possible to use 2 transducers (1 each side)and connect both to a T cable and then to head unit. Bit of added expense though

I would try and sort out your normal depth sounder readings first though. Good site for info is in the electronics section on www.thehulltruth.com
Some very good info on there as USA have been using these units for longer than us here in NZ

I wonder if the transducers are too close together and interfering with each other?
