1911Colt

For a ridiculous $6,000, they ought to just send you a whole new unit no questions asked, in fact I would demand it, the one you got could be a lemon giving you problems for years to come.

Yeah, the SD2200D I would not bet on being better, but I would bet on it being discontinued with minimal if any parts and service support. I had a SD2200D and GPX all the way for me.

Ok cool man, thank you

The one and only I've used is a Minelab Pro-find 25. Very sensitive, its been good for me for clearing out surface junk signals quickly as it will sound off on smaller trash items up to 8" away. Good little sidekick.

Hey Steve, I've been looking for a GPX 4500 to buy, in the meanwhile I've heard the SD2200 is even better/deeper on larger gold, which a coin cache would indeed be.  Any thoughts on that?  The hunting area is mild ground if that helps.

Ok I cant give away all the secrets but if I could completely eliminate the issue of ground noise I'd be rich. 

The sP01 will enhance a little ground noise. Unfortunately thats the nature of the beast but because it will enhance those deep faint signals, you can back the gain/sensitivity off a little which will quiet the machine with regard to ground noise, without loosing any relative depth. You can also run higher smoothing/ lower stabilizer.

So is it safe to say the SP01 takes signals that are likely target signals and specifically amplifies only (or mostly) them?

Is there a website you can order Lidar images from?

Very good ? Well, it seems I'll be purchasing a GPX 4500 then

A GPX with stock coil can hit a U.S. nickel alone to about 16-17”. I would estimate 2-3 feet to be fairly easy but it depends a lot on how the coins are packed in the jar, orientation, and whether it has a metal lid. Nuggets weighing multi ounces but far smaller than a jar are found at depths exceeding two feet with a GPX.

My favorite “large” coil for a GPX was the Nugget Finder 18” round mono, but with over 100 compatible coils having been made the choice is vast.

Bang for the buck is the GPX 4500 but the 5000 if money is no object is still in many ways the most powerful general purpose PI device on the market. For your use though the 4500 would probably be the way to go.

Thank you sir, I greatly appreciate your insight, anyone can have an opinion, but what you gave is insight.  As far as if it had a metal lid or cap, say iron, would this affect the way the GPX detects it?

Used them myself also. They simply find what they find and won't what they don't. Treasure hunters have used them for decades and so this is not even an open question. However, If you don't want to use a two box get a Minelab PI with a large coil.

What kind of depth do you think a Minelab PI would get on a coin cache jar?  And as for coils, which would you recommend for this kind of hunt?

Yeah, what I mean is for caches of coins, the depth is miserable on them, all the literature makes them sound good but once you have one in hand you see they are poor performers, unless its a very large object

Thanks for the replies, as for the White's, I forgot to mention, I took a TM-600 and also a TM-800 up there looking, after no results, I tested them on buried targets, those machines are also nearly worthless, wouldn't even find a bundle of copper pipes at 3 feet deep, and even more worthless on a jar of coins.  People say yeah 2 box for deep stuff, but in reality, unless you're talking about a steel drum or something similar, these won't find anything.

Hey, I'm new here, but I come here time to time to read, you all are a knowledgeable bunch it seems.  I have for a couple years been on the search for an alleged cache of gold coins, in a jar or something similar. It's a solid story, I've done my research, etc.  I am currently looking into a GPX 4500 for the hunt. I had bought a CTX 3030 and learned it for a few months, but I buried some test targets (using bottles of nickels, or pennies), and the damned thing was nearly worthless past 12" deep, a $2500 toy in my opinion.  Most caches are said to be found at 1 1/2 to 2 feet deep, and I'd say 3 feet wouldn't be out of the question here.  Any informed opinions welcome, thank you!
