We went to Wedderburn on the old diggings on Monday Public holiday.
4 detectors:
Minelab GPX4500
Minelab Extreme
Garrett Gold Stinger
and my X-Terra 705.
Only the 4500 found 1 piece of gold (Around $40-$50 piece)
The coil went well, but on highly mineralised soil it kept picking up targets everywhere in prospecting mode.
I switched it over to coin mode and the targets were 42-48? right up the top end on the display.
I assume these are hot rocks because I hadn't come across them before.
I kept one of these rocks, I'll take a photo of it and post it here.
I think that if you had this detector as well as a GPX5000, you might be able to use it to tell you where the gold is, then use the GPX5000 to find it.
If you are after a detector for gold prospecting, nothing will beat the GPX5000. It will find pieces of gold worth as little as $5.00, as well as the larger nuggets.
I had to use my detector in Coin and Relic mode and block out the top end numbers for it to work in this area but it would not be as sensitive to smaller pieces in this mode rather than prospecting mode.
Being from Russia and not Australia, it would assume that it would not be designed to suit our highly mineralised soil.
I found a lot of bullet shells, bullet heads and a few bits and pieces.
I think this coil would better suit coin and relic detecting in non-highly mineralised ground.
I did an air test on a can of coke and it showed around 1 meter!
The 50c piece showed at around 400mm. (I did not get the number it displayed)
I will do an air test with all Australian coins and post numbers and air distances.
Can't wait to get it onto the beach! - Very happy with the coil so far.
It also detects things around 2 inches away on the sides of the coil, so if you don't go completely over the target you will still hear it.
The coil weighs 733 grams.
If you want any other information, or live around Bendigo and want to do your own tests, PM me.
I will not get these coils for anyone, if you want to buy one you need to get it by yourself, I did not know that no-one else besides Minelab is allowed to make X-Terra Coils until after I bought it.
To Minelab: If you would like to see this coil, please PM me. If you can make a coil that will match this one, I will gladly swap it with you for one so you can pull it apart and test it.
