Depth On The Golden umax

[Whimpster]

Ken...I find all metal gives me more depth... sketchy tone will become a solid tone but it's still just a single tone. You can tell a lot from that single tone but you might not know if you have a signal that you want to dig. It could be a nail or a coin because while you gained depth, you lost discrimination...so by switching to disc you can determine wether you have a iron sound or multi tones...
I've tried my Mojave coil but its way to positive in ground balance...and the Golden would need to be adjusted to that coil... haven't tried the 5.75 yet...I mostly hunt sports fields and parks with this machine.

Whimp, thanks for the all-metal tips and the heads up on the Mojave coil. I'd read somewhere that putting a smaller coil on a fixed-GB machine would make it balance to the negative, but I guess that's not always the case. My worry with the stock coil is that it'd be too big for some of the trash-inffested places I like to hunt. How do you find its target separation?

Ken...it depends on the coil..my original 9x8 coil is a tad negative...my 8" brown coil was a tad positive..so I adjust the internal GB to match what ever coil I'm using... I like my machine to be a tad negative. It's not hard to do
The original coil is not bad...but I like the 8" coil the best overall for separation and depth..7" coil off the Movjave is a good coil for trashier sites...good separation just a bit less depth.
It's good to find a coil that works best and leave it on..gb adjustment is very delicate and it doesn't take much to move it positive or negative.

Thanks again, Whimp. I think I found a thread on these forums where you compared different coils on the Golden Very informative!

To set the internal GB, I'd need to remove the knobs and face plate and tweak an internal potentiometer, correct?

Oh well, I guess I won't worry about that until I actual get hold of a Golden

Just bought one with two coils for $260 in mint shape-I had one before but didn't like the depth on it and sold it but always kept it in the back of my mind to get another and experiment with it.
There is a lot to be said for the notch feature especially if you can vary it from narrow to wide.
Hope I give it more of a try this time.
I just sold it too fast before
