This new post (even thou he dont know the right designation ) seems to be sounding better..... but i think he needs some more time on it. He talks about sweep speed being as fast as the Nox..... yet Tom made a special not to say.... thats one factor for loosing depth. I noticed he had all these machine including both Nox..... give us some air tests. He mentioned earlier he wasnt going to do comparisons......but that what we kind of need. im waiting to see what he calls micro gold, his definition likely isnt the same as mine. He mentioned earring studs...... were they gold because the Nox goes really deep on the high conductor junk ones too. IF sweep can be done moving faster than an Xcal while retaining depth and we can get some depth measurement on GOLD.... i mean lets face it thats why we buy water machines then we are in the ball park.

Yup, all the new technology, machines that can find gold the size of a grain of sand and so deep you have to buy a backhoe to get it out. In the meantime, OBN is filling his treasure chest to the point of overflowing with the old trusty Excal. Isn't life of a pirate great Joe.

I'm good and a few PI's somewhere.

This looks so interesting...wish this thing gets releases soon, I'm really curious to see some real time results.

Credit Joe with the right tool for the job........ but i give him more credit for finding out of the way spots that really produce.

Tom said hes working on the manual now and trying to get his supplier to produce the phones they promissed. Though they might just release the machine and put what ever adaptor we want on the pig tail. Based on some of his posts....... it was better than the first Manta, but i dont know if that was based on the same choices we now make between a PI or a VLF..... simplicity with less digging. OR ..... shear depth on gold targets that are ring size.

Until there is a new unit that can tell the difference between 24k and iron I'm good with my whites tdi.

Yep... this is the one Lama and I tested. Did I not say the name rhymes with a woman's designer clothing line?



A couple hours on the beach wasn't enough. I really would have liked to use it for a week or two. None the less, thankful for the experience.

Steve..... not sure what you mean by that? A good bit of my gold from the Nox have been 18K and above..... 2 were 22K and 1 was 24k which the Nox had no problem seeing and they werent down there near the iron range if i remember right.

I use pi's.. had a gt, cz21, ctx among others. The ring/jewelry designs over here have a hard time being hit. I'm interested in a new type of technology similar to pi or a pi that knows the difference between 24k and iron at depth.
I haven't tried a nox and there are plenty of them over here. But I dont know of they are hitting what I'm looking for past a few inches
