If it were showing me nine feet and it just covers a third of the water, should I just be fishing three to four feet deep ? The images do go by at different levels. If for instance four or five were in the lower portion,would that mean I should be fishing at perhaps seven feet? I haven't seen an arch of any kind so far with it! I guess I should have two or three poles at different depths .
Fastfish. Most depth finders give a depth readout of the fish shown Using fish icons could be iffy.Smarter fisherman than I am do not use the fish symbals because the unit can be fooled by turbulance, air bubles,tuttles, floating leaves, and tree branches, and etc,. It takes a while to learn to interpret the sonar information.I am not saying fish symbals are all bogas, but your sonar unit can be fooled into showing the icons when they are not really there. You can look at the right of your sonar screen and determine fish depth. Some units show this information in 5' increments and will help to determine the actual fish depth. If you are fishing in 9' of water, the amount of bottom covered would be about 3'. This would be like turning an ice cream cone upside down. This would mean fish located closer to the surface under your transducer would have a harder time being in the cone. Sorry for the long post. I can appreciate what you are going through as I had the same problems trying to learn to use my Elite 7 HDI. I am still learning but I will always help because these guys on this board have always helped me.....Good Fishing and Have Fun.....crappie1133
