Couple things

[Dancer]

Was always concerned about where the speaker holes are on the X. I never hunt without headphones so. I bought a roll of "Black Gorilla Tape"
Covered the speaker. Eliminates my worries of moisture from wet grass, light rain etc. I've logged many hours with this without any ill effects. This is something you got to decide for yourself.
Another thing. Many fine videos on the X. Could be, but I haven't seen any on how helpfull the duel discrimination aids the average coin shooter.
The settings to eliminate the Beaver tail tab from the nickel and gold jewelry are very good for this. But I'm darn sure I don't have it completely right. I got it working for me, but watching a video on this would be great. I've hunted the X on a couple of beaches and it is now my machine for everything except wading of course.

Since I always wear headphones, did this right from the start.
I covered my speaker hole with a small piece of plastic and waterproof radio box tape, sold at hobby shops for radio control boats.

Not sure what the average coin shooter really is, strictly coins? Or accepting jewelry?
I hunt coins and jewelry and the way I use both disc controls is opposite than most would. But, for me it works coinshooting while also hunting jewelry.
For strictly coin shooting you can set up the controls the way I do just increase both disc controls to match what your looking for.
Alt Disc always higher than Main disc. Which then gives you a notch window, when switching back and forth.

You hunt in main disc, if you get a high tone dig-coins-silver. If you get a low tone, switch to Alt disc. for checking. If you still get a low tone-junk, no dig. If you get a high tone, lower conductor coin-dig.

For strictly coin hunting, bump the settings higher. I use the numbers below for a combo coin and jewelry hunting, in which if I switch to Alt and still get a high tone, it could be a gold ring.

Alt Disc
0<--------------------------->25<------------------->

Low Tone High Tone





Main Discrimination
0<------------------------------------>35<----------------->
Low Tone High Tone




Combined Disc Window
Main Disc--- Low Tone, Alt Disc –--High Tone

25<--------------------------------->35

Yeah, covering up that speaker.ain't gonna hurt.
Average coin / Jewelry hunter would be someone hunting around parks , beaches. Mostly (in the States) Trying to pick gold / silver amidst pull tabs, can slaw, mostly. Nails around bond fire areas.
Right now I'm setting my first discrimination close to 30.
The second discrimination, over a beaver tail tab, I turn the knob until the tab starts to break up, but not discriminated out. If it crackles ,best chance ( nothings 100%) it's a beaver tailed tab. If it's discriminated out , that's where I get my US nickels. Keith Southern suggested this tip to me. There's No Doubt this can be better explained by many.
Many videos made for a lot of machines concerning relic, silver hunters. A lot of hunters don't live near or simply don't care to brave hunting in iron infested sites. A good video would be laying a nickel. A tab, and a couple gold rings down. Come up with a couple notches.
