Side scan imaging around boat docks

[insuranceagent]

I apologize if this has been asked before but I'm curious how well side scan units work for seeing under docks? I fish loz and mostly fish around docks so I was wondering how well you can see under the docks and also if you can see under them can you see all the way to the front of the dock or only under the back? Thanks

Well.....it depends. How's that for a definitive answer? Depending on how you use your SI, you should be able to see some of what's there. I think there are two separate beams of SI....one shoots down/sideways in a cone slice, and the other shoots out in a rectangular slice(which should show you what's higher in the water column). When I scan dock cables, I can see the concrete block and the cable going up, but can't see it going all the way to the surface. Try asking this in the main "Fishing Electronics" forum and you may get a better answer.

some where on here I posted some pictures of side scan under docks, they were ok, but you won't get much detail, best way to fish docks is to fish them all, start in one place and work your way to the end of the line, somewhere you will find fish, and once you do, they will most likely always be there, work it over pick it apart, also look of tell tail signs on the docks, cleaning station, wire or small string going straight down in a slip, rod holders, little things you would put out for your catching pleasure, someone else is probably doing the same thing.

The best thing about side scan is finding structure. You will be able
to tell if there is brush piles, cedars, and such around the dock.
This can save you a lot of time fishing unproductive docks.
Good luck.
