Default GETTING FISH TARGETS WHILE UNDERWAY....??

Historically I have gotten fish targets while the boat has been underway doing around 25-30mph using my Lowrance LCX-16CI w/ a 200khz transom mount ducer in less than 50' of water.

Now I still get the bottom while underway but the picking up of fish targets is eluding me and the bottom image displayed is less detailed. I checked the position of the ducer and it is good and has not 'kicked' up.

Do you guys pickup fish while using your unit or are you just happy w/ getting the bottom..??

I have the same unit and at cruise of 22-25kts I do not see any individual fish with a T/M 50/200 in either freq. . The only fish that show on mine at speed are the rare large , tight school. Maaaybe large tuna or similar.

I'm interested & surprised you used to see fish at that speed- I'd think they would be no more than tiny specks or short vertical lines on the F/F at most as they pass by the sonar cone at 30mph, though if you have a single freq 200khz T/D that might well have superior performance to a shared freq. T/D. .

Bottom picture is usually pretty clear and good at speed in 200 khz though, but obviously not with the detail of slow speed returns.

If you used to see fish , perhaps a better combination of manual max sensitivity/gain & min. noise rejection and T/D face cleaning can get them back?

You don't use "Fish ID " mode that shows weed as fish symbols , do you? Sorry, had to ask .
