GRAPH QUESTION. Where are the fish?

[SeedTick]

Guys, I've never had a good sonar before so I really don't know much about them. I could tell the depth of the water and that was about it. What I'm having trouble wrapping my pea brain around is; where are the fish in relationship to the boat. My new graph (Lowrance X107C) uses a dual cone angle transducer at 35 and 12 so I've kinda got an idea about the size of the area I'm looking at. The graph speed is faster than the boat speed so does it show the same fish more than one time if I'm trolling really slow? Here is another thread with a picture of a graph that I am keeping an eye on.

Keep one thing in mind when using any graph.THE ONLY thing that is current on that screen is the right hand edge.The rest is history.Any fish arches you see and your picture shows some dandies around the baitfish, are directly under the transducer cone.So if the transducer is on the rear of the boat by the time you "read" the graph the fish are behind you.Also keep in mind that good arches are a function of the boats speed,higher speed more defined arch.If you are sitting still and a fish slowly swims thru the cone it will look much more like a straight line.The scrolling speed of the graph doesn't relate to boat speed per se.just increases the definition or amount of pixels turned on as the fish passes thru the cone.Go to the Lowrance website and get on the product emulator for your unit and practice practice.;) :) Or take the tutorial which is the best explanation of how sonar works and all the Lowrance features that I have ever seen.:)

That's the stuff I need to hear, the left side being like history. I've played with the simulator and it really helps. I need to get out and try it on the water. We've had a drought here in Arkansas for the past year and since I got my boat and got it rigged up it ain't done nothing but rain. I'm not complaining though because we sure needed the water. Thanks for your help.

Anybody else? When you don't know anything even the simplest stuff helps.

Seedtick. In you pic the D fish are showing at 1-14' and 2-18'. Those fish are not 14' & 18' off the bottom. They are 14' & 18' from the center line of your transducer. They could be anywhere in relation to your boat, front,back,left, or right. Hope this helps. I used to have a tutorial on how to read a depth finder, I'll see if I can find it and pm you with it...
