Infinium Depth

[Anonymous]

Did anyone else read the field test report from Finders? The depths used in the tests seemed really pitiful. A 6.3 gram nugget was tested at 13cm and 18.5cm (5.3 ins and 7.28 ins). A 32 gram nugget was tested at a mere 20cm (7.8 ins). Maybe these depths are acceptable for the really hot ground the tests were made on? Would anybody with experience working this ground please comment.
Also, what is the battery pack the infinium uses and how many hours of operation does it provide?
I would like to see the results of air testing an Infinium with the gold nuggets which range from sub gram size on up as well as a selection of different countries coins. A US nickel (5C) would tell us a lot more than a nugget as the coins have a consistent shape and content from one to the next.

Hi Dave
I know that there are heaps of 1oz / 32gram nuggets out there at about the 12in mark that the Minelabs can't detect because of the mineral ground but I would like to have seen the 32 grammer tested at a rather greater depth. I have found gram nuggets at depths aproaching 7 in but can't comment on the tests because the realy hot ground does certainly affect the signal. Planted targets are also a problem in that the ground is disturbed so that it is not in a natural highly mineralized state.
I would also like to see some air tests on small (say 2 grain/.1gram) nuggets. I want a waterproof detector that can find small gold in the local creeks where the mineralization is not usually too much of a problem. I am also a bit concerned about the different versions of the Infinium it is just possible that the US version might be better for low mineral underwater work?????
Something to think about
Cheers
Steve D

Dear Dave,
These tests were done on very high mineralised soil. The SD2200D was also tested on these targets with the 11"DD coil. It could only achieve the same depth.
Remember, these were buried targets, and you should not expect to get the same depth as a undisturbed target.
The 5.3 gram nugget was first buried at 13cm and both the Infinium and the SD2200D easily detected it. The VLF detectors we had at the test, could not even give a slight reading on the nugget.
The main thing was that the SD2200D and the Infinium basically had the same depth capabilities.

Phil,
It just goes to show the value of testing a detector in the conditions it is to be used in. Dave. * * *

I conducted the test for a guy on the forum and got 12-14 inches in zero discrimination. My buddy, Jim Straight, in California got about the same results. Believe he said 12 inches plus.
