If like me, you're new to the whole, techo fish finder thing, maybe this will help, in regard to reading the side scan thing, in the fishfinder.

I've been using an older Humminbird 535, which Mr Inky very kindly gave to me. Now I've been bitten by the 'new fish finder' bug.

When researching the newer models, I couldn't make head nor tail, of the side scan/view stuff, so I forced the brain, into research mode and I've prepared a trio of images that help, at least, help me, understand.


The first is the screen as seen on the fish finder and then I split off the left and right sides and rotated them to be, water surface at top.

The second, I've tried to put the 1st screen in perspective.

The third, is an idealised view somewhat akin to an aerial photo.

Thanks for that. My 7sv is on a plane soon so am trying to get my head around this stuff before it arrives. Good for structure, maybe not so good for fish, but at least can prospect a wider area and return over the interesting spots for a better look at if they hold fish.

Any problems or concerns about where to mount the sv transducer?

Using sidescan to target snapper where I am in Western Australia has been very successful for years and a decent sized snapper or a school of them sticks out like dogs balls on side scan .kingfish (samson fish in my case ) are also easily seen on side scan .
Frankly in WA if my side scan is not working I would stay in bed ..
I find the folded paper method of demonstrating side scan easy to understand .
I cant recomend enough taking a bit of effort to master it . Especially when you fishing shallow water .The majority of my saltwater fish is 8 to 15 m .

Thats very interesting, I'm finding my way around the side scan, it all works well enough, but I feel I'm going to have to play with the chirp, the different frequencies and other settings to get a better understanding, my favourite spots at the moment are 10 ~ 20 m. :y:

Somewhat related and something I was trying to figure out for my 7sv install, the beam widths and angles at various strengths/frequencies. The attached doc explains it a bit better.

Thanks for that, yes that seems to correspond with my experience of the 7sv.

In terms of how deep the transducer is installed in the scupper well, mine is about 1cm below the lip laterally, but a little more longitudinally, due to the keel.

Doesn't seem to affect the performance
