I was noticing some of the pro�s had them off on BASS live

If I�m fishing less than 4 feet of water I turn the sonar off on both units. The pinging sound is loud above water so I assume it transmits twice as far below water. I�ve had days when I forget to turn the rear unit off and I struggle to catch fish.

Ultrex is louder then graphs in shallow water.....

I�m not a believer in that. No way it�s louder then a trolling motor.

put them in standby when not looking at them.
pulls a lot of amps out of the battery.
standby shut off the ping and screen.
but keeps the gps current

According to Ralph Manns, you are better off turning your electronics off while fishing. So, I do that. He conducted a 2 weeks test, on a cordoned off cove 1 hour with the graph on, 1 hour with the graph off. He found he caught a LOT more fish, like 325% more fish with the graph off for at least 30 minutes. Who is Ralph Manns? He only writes fishing articles for a whole ton of fishing magazines and he was one of the guys that started the Sharalunker program. He also worked over 30 years as an icthologist for the Texas Parks and Wildlife Dept. So, what he says carries a lot of weight for me, but he may not for you. Hope this helps. Tight lines, keep safe and good luck.

Could be just a habit, turn something off when you�re not using it. I don�t leave my bedroom light on while I�m at work.

On a lowrance gen 3, will putting in it �standby� turn off the sonar? I am seeing mixed reviews when I researched it.

I do when I know the area real well, and also when sight fishing all the time.

I turn the big unit off if I'm on the T/M.. That saves a lot of extra juice for other stuff, I can't recall who told me, but, with the front bird in Di there is no ping, I use a split screen up front, Down Imagiming-GPS trail...
Everybodys different, my deal seems to work for me..

Messed around with it both ways. I put mine to sleep just to save the battery.

Yes. Standby on Lowrance units kills Sonar and the backlight.

Never.

Stand by more here.

Yeah me either. The Whopper Plopper covers the ping noise. Besides I usually slap the water with my lure before every cast so .........
