Quinte Fishing

I need help with a Lowrance Elite 5 DSI. I am very dissapointed with this unit and I am thinking of putting my old Eagle 480 Fishmark back on the boat. The gps and mapping is nice (not as nice as my Garmin hand held 60CSX though ).

I have put many hours on this unit, caught lots of trout but this thing will not ever show a fish arch. I have occasionally marked (i think) bait balls but that's it. I would describe the Elite 5 as a color version of the old Fishmark except that it does not mark fish. It appears to only be good for showing the depth and surface temperature. I don't get the DSI part - the 'picture' it shows of the bottom is the same as the 480 but in color.

According to the manual I should have sensitivity settings plus "fish modes", etc but it appears that it's missing many menus that are detailed in the manual. I have found similar complaints on-line and apparently the DSI doesn't have manual sonar adjustments? What good is a sonar that doesn't mark suspended objects, shows a 2D bottom and looses bottom at 250ft? What am I doing wrong?

Lowrance shows nice images on their product info page http://www.lowrance.com/Products/Marine ... -DSI-Gold/ but these images are nothing like mine. I don't need 'fish id' or fish alarms but if it can't mark a 10 lb trout down 50 feet what good is it?

Sorry for the rant but I am very dissapointed in it. I am concerned that it would be better mounted to a fence post in the back yard. I would appreciate any advice; if it won't do what I expected of it then I will either sell it or shoot it.
