Yesterday I decided to try just coin shooting with the G2 DP for high conductive coppers and silver. I recalled reading someone say to just crank the disc all the way up so I tried this. Also I cranked the gain all the way up as well. In order to ground balance though I had to lower the gain temporarily to say 30 and perform this task due to some EMI at high gain settings. While hunting in 100% gain and disc settings I started plucking a lot of coins at depth down to say 8 inches or so. Found a hand full of wheat backs and Lincolns and a few clad dimes. My buddy was able to find a very good 64 quarter and 59 dime in the same field the previous day with his Fisher CZ5. I did not find any silver but the amount of coins I was finding increased dramatically. Amazingly, there was iron junk next to most of the coins I found as a check in all metal revealed. I did get the occasional grunt or null on each of the coins when sweeping, however, if it gave the slightest hint of a coin, the G2 was batting 90% and at very good depth. I dug very little trash. I am liking this detector more and more. An amazing machine in the iron. I doubt some other detectors would have found these coins. This field has been hit hard by a local detecting club.

Observations On Coin Shooting w/ G2
- Thread starter lloyd0161

At maximum discrimination you lose zinc pennies and most screw caps and everything below that.. You can kiss some Indian Head pennies goodbye as well. You can lower the discrimination some and take note of the ID numbers to see if you want to dig or not when you get a high tone. There will be less masking doing that way.

I find that to be true also.----Bear in mind though---anything (target) you have disc'd out by a good target will "over-ride" that good target.----For instance, a nickel by a dime & you will never know the dime is there.----That's (one of) the prices we pay for high disc settings.-----They are still worth using in some situations though, depending on the site & your mindset/mood.

Thanks guys. When I have more time I will be taking some found coins over to my field to play around with this and see what might be overlooked. Usually I hunt with no disc or disc set to say 40 so I basically hear everything. The max disc was an experiment to see what happened when you knock out all signals below copper pennies/dimes, etc. Sometimes this is good when you just want to dig the easier picks and not analyze every target response.
The G2 and Fisher Gold Bug Pro can find modern coins, no doubt, but I encourage caution when using Discrimination ONLY to sort through trash.lloyd0161 said:
I almost always hunt with my G2 at the 100 Gain setting, and seldom, very seldom, use any Discrimination higher than just to reject iron nails. With the G2 I mean to just barely reject (silence) the nails, and that still leaves me with a two-tone audio to alert me to targets of greater conductivity. I also seldom use my G2 in 'average' coin hunting places, however, preferring to take advantage of the sub-5" DD coil to really hunt through very littered places.
Also, the G2 and other Teknetics models to fairly well in iron, sporadic, but are not the best performers sin a heavily littered, iron nail infested site.
readers take heed of this warning! Tabman is quite correct and I have demonstrated issues of lower-reading coins (even though the books list a good conductivity mix) such as Zinc 1tabman said:
Well, Thanks Monte for the above insight. As I stated this was only an experiment with max disc and not the way I normally hunt with the G2. However, at maximum disc, I was amazed at how many coins I did find in a field I know is heavily hunted by a local club using every conceivable detector. I usually run the disc value at 40. This still detects everything, including iron, but gives a low tone below foil or very small gold items or even very deep items that might be something higher than foil. Being able to hear the iron with the good targets helps to figure things out sometimes. In my initial playing around with the G2 I dug an awful lot of rusty hairpins trying to sort out micro jewelry like earring backings, etc. Sometimes I feel like digging everything and sometimes not, depends on how lazy I am on any given day. In the world of micro jewelry and small gold ring hunting there are also an awful lot of useless foil scraps to wade through.

Monte,
Not saying I disagree with everything you wrote but in iron infested sites is where this detector really shines. I own several other machines and they have their place but for iron infested homesites my GB DP is truly my favorite.

Monte,
My response was aimed at the statement that the G2 wasn't the best performer in "heavily littered, iron nail infested sites". Your response doesn't seem to address that directly. I use the GB DP at several old homesites with heavy iron trash, mostly square nails. What impresses me most is how little it falses compared to my other "pricey flagship" machines. Usually a setting of 50 to 55 will null the nails and it runs quiet only signaling good targets. I guess everything should start with "in my soil". Again, it's my favorite machine for this scenario, consistently pulling good targets in the footprint of my other machines.

I have several different makes and models of detectors in my personal arsenal. I tend to grab a detector and coil combo that I feel can best handle the challenges I have at a site.KyJoe said:
If I am living in an urban environment, where a lot of modern coin sites are typically found, then I hit them as would many avid Coin Hunters. Typically, most urban coin-producing sites have more modern-type trash that is non-ferrous, such as small or large foil, pull tabs, screw caps, etc. Do we sometimes find ferrous-based trash? Yes, we might occasionally encounter A bobby pin or A paperclip or even A nail, but they are more or less 'sporadic,' and the unwanted iron stuff is often well spaced.
Most good detectors with a sow-sweep and quick-response can handle these types of iron encounters and do fairly well. I enjoy using my Teknetics Omega w/5" DD or 8" Concentric or 5
The G2 and Gold Bug Pro work very well in nail or iron infested sites compared to most other detectors until you put them up against the Classic III and IDX Pro which score another notch above in those areas. Will I get rid of my GBP because my modified IDX Pro does better in those areas? No because my GBP beats the heck out of my IDX on the saltwater beach dry sand.
