catching fish but not marking them

[jimfish]

I have a Lowrance HDS5, we have been catching fish consitantly out of GH but cant seem to mark anything but, what look to me like schools of bait. Is this a common situation? My graph seems to be woking fine, any input would be great. Thanks.

Can't say wether anything is wrong with your lowrance. But we don't mark what we catch most of the time. It's not gonna pick up a fish caught on a 2 color that 100 ft to the side of you're boat and only 10 feet down

I notice with my Furuno that it marks fish better on the split screen setting. 50/200 mh.

If your marking big bait balls, fish them hard.

go into the menu screen take the gain off of the automatic setting

turn the gain up intill you see clutter then dow just untill 90% of the clutter/static goes away

you will now mark the fish

what prop nut said and also turn your ping up to 3/4 speed. also check to see if you are on wide or narrow beam with your transducer. Turn your noise reduction and surface noise filters off i believe they are set to low from the factory.

Jim this March at the fishing show plan on coming and going to a seminar by lance valentine called Sonar the basic and beyond. He also does one on the gps unit. Both are an hour long and more than worth sitting through to learn how to set up your sonar properly. This summer onerie was the first time i could mark fish while running and be able to tell they were fish i was going over all due to the info he will give you in that seminar. I learned more in an hour than what i have learned using these things for the las 25 years.

With lowrance units for fishing the big lake you want a HST-DFSBL 50/200kHz, 35°/12° Skimmer Transducer. The 50kHz has a wider cone angle so you will pick up more fish plus that is the frequency lowrance recommends using for deep water.

I currently have a single frequency ducer on my boat 200 kHz. I went jigging lakers the other day in 175' of water I had the ping speed maxed out and the sensitivity above 95% to get decent mark on 20-24" fish. But I could also mark my jig falling all the way to the fish.
