Lowrance auto-sensitivity or "fine tune"

[speedbump]

I have the Lowrance LCX 37C on my one year old boat. As I wandered around the lake I attempted to "fine tune" the sensitivity. Never really had much luck. The only time whre the auto sensitivity worked incredibly was on the hard rock bottom of my favorite Canadian fishing water. On other lakes such as Minnetonka, the auto sensitivity works fairly well most of the time, but I was wondering if there is a secret to get them to work perfectly all the time. Maybe there is a good combination of sensitivity and scroll speed??

I leave my scroll speed as fast as possible.

At times I adjust ping speed and sensitivity. The majority of the time I leave them on the automatic settings, but if I'm in weeds or hovering over an area and looking for transition breaks etc. I might manually adjust the settings to get better readings.

I turn the auto function off on my graphs and set the gain manually which seems to work better. This is even more true in weedy areas of shallow water where many people seem to have issues.

I adjust manually. As others have said. If I am shallow in some pads or weeds, the sensitivity is important in not losing bottom on the graph. Nothing worse than running shallow in new territory and your graph starts acting wacky.

Can you expand on this? I'm pretty familiar with sensitivity adjustments, but I have no clue what adjusting my ping speed will do for me.

If you're in weeds or heavy cover, slowing down the ping speed seems to give a better, more clear picture.

In deep open water, over rocks, a faster ping speed works good.

Thanks. I often times have problems in weeds, so I will have to play with that.
