Why do not you know the fish arches hds-8 at a frequency of 200 Hz?

Last swam on the water with a depth of 3 – 11 meters and a resolution of 200 echosondzie not see spots and arcs only seen at 83 arches.

Here are the photos of the sonar at various depths:

Such spots can be seen at a frequency of 200:

We ask for directions (about) why it shows.

I have a HDS-8 and structure scan – transducers are placed 40 cm from the engine. A distance between the transmitter and structurescan HDS is about 15 cm. I swam only the transmitter HDS and the results were the same – ruled out (know) that there is no interference from structurescan.

I know that for drdepth records are recommended at a frequency of 200 Hz so please help!

Also installed a sonar transducer with LMS-527 (HST-DFSBL) but the effect was the same – at a frequency of only 200 spots.
Is it possible that the spots because I swim in the shallow?

Which is better processor and WSBL HST-HST-DFSBL?

At 200 hz can not see curves (^) on the frequency of fish and 83 are visible.
Why does the 200 do not see them but only some spots?

Why is there no such shapes in 200 hz fish that are at 83?
Of the 83 visible arches (^) and the 200-none – shows me why?

Let me see if I can dig up a great article I found a couple years back that does a really good job explaining fish arches. I’ll post it a little later if I can find it.

Here’s a start, there is a better one yet, ill keep looking. http://www.lowrance.com/Support/Tips-and-Tutorials/Sonar-Tutorial/

Here’s the one I was thinking of, thanks to “Doc” Bruce Sampson, and his website hightechfishing.com

Try increasing the screen scroll speed on the 200 cycle side.

Also, make sure you have the correct transducer model selected on your unit. I have seen this before and I believe this is the problem.

I have chosen a good transmitter.
Do I understand that I have to reduce the speed of scrolling (scroll speed)?
