I watch 1/16oz crappie jigs in 30 foot of water all the time. One of the things I do is to turn the contrast up to about 70 to 80 percent. I leave the senseitivity in auto but use it around 90 to 95 percent. The most important thing is to make sure that the lure is in the cone angle under the transducer, if not you will never see it. you might want to check to see were the thansducer is aimed. If it is on the trolling motor and turn a few degrees from straight down the cone will be aimed right or left and may be off enough so you wont see the bait. Also if you are shooting the beam through the hull you may not get the bait into the beam depending upon transducer location. Hope this helps you out.
