Yes, about 75-80 of them. Magnum sand bass and 15"-16" Stripers.

nice!

Guys checkout itainttv.com the professor, Wilson Frazier and check his YouTube videos. I have his dvds and they are great. If the transducer was not installed correctly then the depth would be way off and that should be easy to check. No matter how expensive the unit, 3D, whatever, if it is sonar all the unit can do is measure time and distance and display it on the the big fancy screen. Those streaks just mean the fish is moving fast and either getting closer or further away from the transducer. Left to right is Time and up and down is Distance. If the top of the line is tilted left the fish came towards the transducer and if the top of the line is titled to the right it traveled further from the transducer. When you see a flat horizontal streak cross the screen it means the fish is staying under the transducer at the same distance.

so are you saying that you don't know that they are also?

It is fish swimming upwards my helix 9 mega does the same thing I seen it yesterday under the 2 mile bridge on tawakoni and as the surface started to explode we started catching bar Sandies and crappies,we are used to always seeing fish while they are horizontal but vertical produces a return signal that I believe is feeding fish.

Yep. I always thought they were fishing coming up but now don't know. I thought that I was really one of the few who had trouble reading the graphs but seeing how there are so many different opinions and only one is going to be right, it just showed that maybe I'm not the only one.

This is correct. You do not get arches if the fish are moving and feeding like in the picture.

Just exactly how do you "set" a transducer? I installed my transducers on the boat and on the trolling motor then I set up my electronics. I have never heard of "setting" a transducer.

Those are interesting screen shots. I have not quite seen fish appear like that on my graph. However, I have seen fish move in directions in a very consistent pattern.

With regards to arches versus streaks, there are a lot of variables that contribute to how the fish appear on the graph. I get both appearing on my graph, just depends on boat speed and what the fish are doing.

I'll post examples of both for what I see on my equipment. Same transducer, same settings.

Arches are usuallly your bigger fish. They are a more solid target for the transducer sonar to bounce back from. You want to see tightly formed dense arches. They are the good ones. Go with someone like Mark Pack who knows deep water electronics. He will check a number of spots with echoes looking for those he knows are solid bass before fishing.

That lower pic in the post above looks good. You should be able to catch those . Tight arches up on the structure feeding.
