pelican, those fish are pretty small. The thickness of the arch gives them away. the ones on the left side of your screenshot are the biggest and the furthest to the left is the biggest one and I'd say 12 to 13 lbs. jmho of course but I've had pretty good success at telling how big fish are by seeing them on the screen. The way I do it is picture how many of that particular fish will fit between those hash marks ... in your's you have a 7 ft mark then a 14 so I copied the image just to make sure I was right I copied the thickness of the biggest fish and I got 7 of them to fit between the 14 and 7 ft hash marks which was what I guestimated it at ... 6.5 to 7 and that means that arch is showing up as 1 ft thick and depending on your settings like if the sensitivity is set about 60% and those being catfish then that's about the return you'd get on a 12 lb'r .. a 35 to 40 lb fish will be about twice that thick. Now if you have your sensitivity set to max then that might be about 7 or 8 lbs so it's all relative to what you have your fish finder set at and the best way to make certain of how big a fish is on your screen is by dropping a fish down with a heavy weight on the end of your line and the fish tied just above the weight ... drop it down so that the transducer picks it up on your screen and then see how thick it is on your screen ... when you do this it'll be a continuous long line on your screen ... not an arch because you're not going past it ... ifit just stays in the path of the transducer it just creates a long line on the screen ... you'll see the weight below it also so that's the best way to learn your fish finder is to drop them down there and see how thick the line is created by the fish ... then when you go over one of similar size it'll be the same thickness on the arch as the one you dropped down there. Do this with several different sizes of fish ... like if you catch a 35 or 40 lb fish drop it down and see what it looks like ... you'd also have to take into account what depth your fish finder is auto adjusted to ... like on your screenshot above you've got it auto adjusted to 28 ft and what that means is you're putting 28 ft of information on your screen at that point ... so if you move out into deeper water and it auto adjusts to 56 ft then what you were looking at when it was on 28 compared to autoadjusted to 56 then the arch will be half the size it was when you were in 28 ft of water so like if you've went into deep water and your screen goes to like 80 ft then any arch that appears to be about 1/4 inch thick on the screen will be a hawg .... maybe around 50 lbs or bigger so also if you've gotten into shallow water like your screen is adjusted to 14 ft and you see the same size arch then it's liable to be just a few lbs but if you can tell it's a foot thick in 14ft it'll appear really big on the screen but you can guestimate it by looking at the hash marks and figure up in your head how many of those arches will fit between the numbers listed on the right side so if you see 4 and 8 on the side and 4 of those arches will fit between the 4 and 8 then it's about a foot thick just like when 7 of them fit between 7 and 14. this might seem remedial as you're reading it but it's sometimes hard for folks to think like this when looking at a fish finder so that's why I"m taking the time to type/explain this. It's also the same on side imaging ... you've got it set on 37 ft on both sides and most of the fish showing up on there are about the size of large shad. also those shadows give you information as well. when you see those shadows a long ways from the fish that are making the shadows then those fish are suspended quite a ways from bottom. like if the fish is half way between the shadow and where your side imaging is making contact with bottom then that fish is suspended right at half way down. if you can make out which one is creating the shadow and it's about half way between the shadow and the bottom then that fish is about 7 ft from the surface if it's 14 ft deep there. This information is very handy as sometimes all the catfish will be suspended quite a ways from bottom and it's necessary for you to get your bait up close to even with them because fishing on bottom won't produce in a situation like that if none of the fish are on bottom .. I ran into that for over a month this last late summer/early fall.

After going back and looking at that side imaging ... you probably coulda thrown a net there and caught plenty of big shad cause that's what those look like ... there's a few fish there but mostly big shad.

Hope this all isn't too convoluted so that you don't have a problem understanding what I was saying.

Tiny beat me to it. I was going to say that those were big gizzards on the hump and probably catfish on the left. Everything else he said was completely his original idea.

Does the different colors in the arch indicate anything? Looking to buy my first boat and trying to figure it all out too.

Tiny, Thank you for taking the time and effort to share your thoughts, very informative.
I'll need to read this a time or two and do some ciphering to understand all of it.
Hopefully someone will post some good sonar shots.

I love posts like this. Always very informative. Amazes me how good guys like
Tiny are at reading a sonar. My biggest problem is I have yet to get my unit dialed in to the point of getting a nice clear reading like some of the pics posted on here.

I couldn't make out too much about what was on the left side as it looks like he was turning left right before taking the screenshot making those on the left side appear to be very long and that's not the case ... means the ones on the left were staying in the path of the transducer longer due to the left hand turn and the ones on the right were little blips because of the same left turn.
