I just upgraded from the strata 128 to the 480. Would any of you 480 users mind sharing what settings you use as far as sensitivity and grayscale? I'm having trouble getting the unit set up like I think it should be. Right out of the box on auto, it seems that it shows any little bit of brush as a huge pile but I know it's not because I've fished it before. You can drop a hook down there and drag all around and never hang up. Maybe just feel it bump something every now and then. Then, when I go fish a brush pile that I built with 4 or 5 large trees in it, it looks the same as the small place? I've varied the sensitivity up and down without much luck. The other concern is chart speed. With the old Strata, it would show brush 20' to 30' away from the center of a big pile, like I think it should, while with the 480 it seems you have to get much closer, like 10' to 15' to start showing up. I have the chart speed increased to 100% and the hyper scroll at 100% also. As you get close to the brush, the hyperscroll seems to help but I still think the old unit showed you the edge of the brush better. One other thing...All the adjustments I made to the sensitivity issue were with the unit in auto, which is the only way I ever ran the Strata. The manual says changing the sensitivity while in auto will only bias the unit toward that setting while it will still make adjustments to keep a solid bottom lock. Any sugestions on what settings to use or any other help is greatly appreciated. Thanks.
