Thread: Lowrance troubles

Gonna try doing this as short winded as I can. I've had 2 gen2 touch units for a few years. When I first got them everything was great and I was catching the fool out of fish. Last winter I put a software update on it and things haven't been right since. The 2 units will tell 2 different stories and I don't know which one to trust. I can't catch fish like I was and it's got my confidence level low.
I finally spent the better part of yesterday fooling with the settings. If I keep the surface clarity medium or high I mark fish in 6 to 12 ft of water but there is none there to catch. Is high the recommended setting for this.
Also what is recommended for noise rejection. At the same time I keep the sensitivity on auto and adjust a little. Yesterday I was in the middle of a huge flock of diving gulls and could never mark any bait clouds like I could before. My question on that is, are they any quick settings tips for lowrance like I have seen for hummingbird.
Thank you all.

Because I know the waters I fish in very well I just leave mine on auto sensitivity. I have played with the sensitivity enough that I don't leave it on auto because I don't know how to use it but because that works well for me. I do change the water clarity mode though to match the lakes conditions. A few years ago when life was going to end because zebra muscles had invaded my home lake I found that a side effect of zebra muscles was that the make the water really clear so I had my units set for clear water. Later the lake flooded several times and the water stayed stained for a long time so I set my units to stained water. I leave mine on auto because I have found that increasing the sensitivity will make my display show bait or debris give an inaccurate impression of what is under me. This is what works for me. Once I learned that the sensitivity adjustment only changes what I see but not what the sonar sees I began to trust the auto setting more and worked at interpreting what I see without making adjustments. Admittedly what works for me may not work for others. There are large numbers of striped bass in Texoma and they predate the crappie and that makes the crappie hard to locate. For me seeing fish or bait is not a problem but determining what kind of fish is. I use the zoom mode often when I am seeing sonar returns a a particular depth to better identify what I am seeing. I also use the split screen showing the returns for two different frequencies. I find the duel frequency display to be very helpful. Because of your question I am going to play with the sensitivity more today to see how quickly I can replicate your issues but being as you did not have a problem until you did a software update I am inclined to believe that is where your problem lies. I will easily admit that trouble shooting is easier for me when I am actually looking at the problem. I will be on the water later today, you can call me if you like and I can go thru settings with you but you may know more than I do.
