hds side scan
Submitted by doghouse on Fri, 2012-03-09 08:39
Talking to a guy at B C F about buying a side scan for my hds10 he was saying it is good to only 30m was hoping it would go to at least 50m to 60m how good has anyone else found them

Might be lucky getting it
Might be lucky getting it working in 30m, truth be told.

I have a humminbird sounder
I have a humminbird sounder which has side scan (lowrance has structurescan which is pretty much equivalent). I've sounded stuff at 30m like the gemini, and used it to find small lump shapes in 30m too, all while moving maybe 2 knots. Anything deeper than that and you're not going to get much of a reading. It 'might' work to 50 or 60, but probably pretty poorly, and hoping it will certainly wont make it work unfortunately.
I find sidescan really fricken useful, but a lot of people with it dont use it. I recon it is a vastly underrated tool. Give it 10 years and everyone should be using it! Going back to just 2D feels like stepping back a generation. Would be great if it worked to 50m though! If they made a super beefy 2kW version then it might, but unfortunately it seems designed more for shallow lakes...

The HDS LSS is awesome for
The HDS LSS is awesome for shallow water under 30m... but don't expect to find bottom fish using the Sidescan at this depth.... only bait and structure...
If you really want to structure scan past 30m... it is possible to mount the LSS-1 transducer on a DIY towfish :)

only bait
Do you know why it will only show bait (small fish I guess) and not Dhufish for example.

A big ball of bait is a lot
A big ball of bait is a lot larger target than a single small dhuie. Obviously you wont see individual bait fish on their onw. To see fish on a sidescan, you pretty much look for white blobs then an associated shadow. At that depth, you'd be looking at a pixel or so max, so would get drowned out in the noise. 2D sounders on the other hand are optimised for spotting fish. sidescan is more optimised for accurately mapping the ground (though you can see individual fish in favourable conditions in shallow)
