Lots of ways to mitigate EMI, I choose to hunt quietly sometimes, other times I blast it up high because I can deal with anything including a bunch of noise.
That was learned over time though, gotta work up to the noisier ones because diving right in can make you crazy.
This can get deep on most quieter settings, the gain is not like most other brands and is way higher than you might think it is.

Hitting an 8" nickel with SL, Disc on 4, thresh on +9, sense on....1.
Quiet too.
Many hunt with the sense in the 40's all the time...and get deep.
Combinations of the sense and thresh will control the chatter, thresh high- sense low, thresh low-sense high, both moderate...a thousand ways to do it that work.
High disc can shut down the noise too.
Recently I have been shooting for deeper high conductive coins at a few sites.
Pure cherry picking.
Disc at 65, I can push the sense and thresh to max and it stays eerily quiet.
A bit of noise at SL but not much to write home about, even notching in one area of choice like nickels only makes it a tiny bit more jittery.
Also the three lowest tone choices are the quietest and the least affected by EMI, 1, 1F and 2F.
1 is what I use the most in disc and it has some great unmasking abilities in heavy iron.
If you can think of almost any setting combination plus combine them with most of the tone choices I have probably used it and I seem to find great things with all of them.
