Helix 10, sensitivity on 10, Surface Clutter On 3, Clear Mode, Jigging mode On, ... 10 million 1� shad/minnows?

Throw a casting net and find out really quick lol??

IIf it is really windy out you will get a lot of stuff like that due to waves/air bubbles mixed in the water column. Likely bait fish but if it was windy could be interference from waves and such. The only way to tell is to throw a casting net one time.

Yeah we were in the middle of a drift on that screenshot
but we had been throwing the net for two hours trying to catch bait and not catching nothing finally we got about a dozen little 2 inch shad in the net On screens like these - most must be even smaller -went through the net -we finally netted some carp and a few decent shad

Yep I bet they may have been the baby shad from the spring hatch. It can be challenging sometimes finding a good sized shad school to catch. Keep at it! Lol

Change ur sonar from 83/200 to straight 200 for clearer images and switch ur down imaging to 400khz for clearer pic,

Thanks.

Was this at night? And what is your ducer speed on?

tag. Thank-you

Ya at night - this was about 2 am - chart speed was on 1, we were drifting so .2-.4 mph.
Earlier when we were scanning for Bait at 2-3 mph with chart speed at 2-3 we had screens like this in several areas. We could see Tiny Shad/Minnows around the boat but can they Really be that many/that thick.?
We couldn�t Find Bigger Bait Schools/Balls- seemed Bigger Stuff was scattered. Tried shallow, mid depth and Deep. Finally netted a cpl small carp and a few 6� shad in 12-16�.

I would say plankton especially since you were at night. I upgraded from a 5si to a 10si mega. When I drifted with the 5si I would set my speed like yours but now with the 10 mega I will set my speed at about 5-7 even when drifting. It gives a better return on what you are seeing. I know traditional theory is to match your speed but with these new units Im just not finding that as true. JMO
