Gain

[stevew]

Why wouldn't you run gain at max I think it would help big time on the deep ones???

According to Andy, gain amplifies a weak signal. It does not increase depth. Sensitivity increases depth. I am still learning ,but I am reading and trying what I learn.

Brother steve is correct. If you run gain at max, all signals (shallow and deep) sound exactly alike -- very loud. If you run gain in the lower, you can identify very easily the deep objects vs. the shallow. Gain does not affect depth at all -- however, if you go too low, the volume will be so low that you may not hear it -- especially without headphones. I run gain in the low 20's and get great results. Right now I think i'm set at 22 or 23. If you read back though my recent post -- i picked up a CW brass buckle at 16". Very faint sound so i knew it was deep before digging. But, it was a very solid, repeating sound, only lower volume. I used to run gain wide open until i realized how much more information you can get just be listening to the sounds.

you can run full gain and get the same info by looking at the depth meter,,,, FYI, just another way to do the same thing

I run my gain at 28-29 and u can still tell difference from 2 inch coins and 8 inch coins

I run my gain at 28 also and feel like there is a subtle difference between mid level and deep targets. The shallow stuff is very clear as the flute sound is mostly gone imo.

I have played with the gain down to 23 or so and it is quite softer but I don't usually run it there as the ground is trashy and as JCWeber said, you can miss those softer sounds with all the other sounds.
