I know absolutely nothing about these SI units, don't have & never have had one, but ....
considering that the condo shows up as white, bait balls show up as white, Bluegill on beds/Crappie around bridge pilons show up as white ... I'm thinking this is a Catfish that is "much" closer to the transducer than the condo. Without the distance markings, it's hard to judge ... but, if that's a 16ft tall stand of boo ... then the fish has to be quite a bit closer to the transducer, or else it's Moby Flathead :p
... cp :cool:
