    There is no detector that can differentiate metal types. Whether it be standard coil or 2-box. This is a common misconcetpion ever since TID was introduced in the early 1980s on standard machines. All they do is measure conductivity. Not "type of metal". And too many things share conductivity levels. Aluminum and alloyed gold, for instance. Also size plays into it, unfortunately.

    So the short answer is: No, 2-box units do not provide (nor will any machine provide) the ability to "differentiate metals"

    Oh yea i get that. I run a ctx most days. I should have made it more clearer. Ferrours / non ferrours i ment. My hearts not set on one yet. Have watched most of the utube videos on them. But still.want more info. I know i wont use it all the time. But im thinking the depth that they are ment to go might be handy. Although i did watch a guy bury a mailbox at 2m. And the gti2500 couldnt pick it up

    These are the remains of an old wreck with cannons..now around 15-20ft butried under sand. my aim is that maybe a 2box might be able to pick up the old remains and find the wreck again

    How about trying metal probes? Make one out a length of rebar. Sometimes the old ways work best. gl hh

    Salt water is probably going to reduce detecting depth on a VLF machine. They say pulse machines go deeper in salt water. I'd try to build a big coil for your Minelab.

    Works great if you like wild goose chases and snipe hunts!

    May you never take one single breath for granted.

    Those pulse coils are pretty simple.

    You might get some info at a place carboncoils dot com

    I was really thinking more along the lines of the universal coil for the Pulse Star II. It's basically just a loop of wire, actually two wires--transmit and receive.

    Thanks for that ill check them out. My 42inch mono is like that. 2 cables in the same line. It works well. I just thought the 2box design might have better depth over that one. I can always get a larger coil however

    My experience with two box: Bought a used one, sent it to factory for tune up, they said it was good as new. Had a post hole digger with a heavy head on it, dug about three foot down, could not detect the digger head no matter how I set the controls. Yeah, it was somewhat mineralized ground, sure not extreme.

    With 18 inch coil, pulse will detect railroad spike, or 100 copper pennys, or pop can, each buried three feet. So i could go real negative here on the two box and say an engine block maybe six feet, but i think you get the point. Somebody knows how to build you a big coil. I don't know the exacts, but it has to be the same Henry's and resistance as what you have, that's about all there is to it. You get something like the universal coil for the Pulse Star and it is two meters square. You'll have to build a frame out of wood or PVC pipe. No question about depth.

    Thats a good point. The video i watched on a giy burying mailboxes at 2m and not picking it up was a bit of an eye opener. Think i might just have to look into a bigger pulse coil. Id love a pulse start or deepmax but there pretty costly

    Yeah, a lot cheaper to get a coil built. What i am talking about looks like a piece of extension cord. You build a frame and tie it onto it. Somebody knows how to build one. You just have to measure the inductance and resistance of the coil you have. Probably uses litz wire. So instead of many wraps of wire, a big coil has fewer wraps, pretty much the same length of wire as the smaller diameter coil. These pulse are very simple coils.

    you can find out the nuts and bolts of building coils, detectors, help and advice on all of it at geotech dot com. Lots of interesting projects and articles.

    I sell both of them, I have used the Whites TM808, It seems the treasure hound is more popular but I have never used it.
    a lot of digging, so I would make sure your in a good area because you can pull up anything.

    I'm trying to recover a strong box filled with 8 gold bars, a significant hunk of perhaps more than 100 lbs. of metal. I believe it's only 3 feet under the surface of unconsolidated gravel and dirt.

    Does any one have a suggestion. I'm thinking a 2 box might be an over kill.. or the perfect piece of equipment?

    Have you considered the Garrett ATX with a 20" coil. It is a ground balancing PI machine that is waterproof has a decent level of discrimination for a PI and with the 20" coil will go down very far on large and small objects. On an aluminum can it will go down 4 feet and on larger objects much deeper!
