Selling it becouse I don't need these items any more.
You are biding in one GPX-5000 metal detector (I have two items for sale and the # 3,my son one's ACE 150, it's sold)
Paid $6,500 AU (each) in 2010, made in Australia. Very Little used since(I found some pieces of gold with these Beautiful Machines in Ballarat,Vic.Australia ).
The serial number is no longer visable on these items,sorry, please don't ask for it.
Photos are of the actual unit you are biding—notice that the control panels, displays, and switches are clean and just like new! All electrical connectors are in excellent shape for trouble-free use.
This metal detector was carefully used about 2-3 years ago and operates and looks exactly like a new machine(see the photos). TheLi-ion battery is in very good conditios and all the other parts too and the all unit is in very good conditions working order,as new!.

INCLUDED IN THIS AUCTION
-GPX 5000 Metal Detector
-11" Mono Search Coil
-Battery:Lithium-ion rechargeable battery 68Wh. Approx. 8-12 Hours use.

A bit of Gold from the Gold Coast

We are now at Surfers staying with Son and GF,( ahhh its great to be living with the kids,eat all their food and shower as long as you want haha ) I have been hammering the beaches here,but it is very hard going, they had a massive storm here a while ago but now the beaches are very sanded up,as they trucked in tons of sand to replace that they lost to the storm.
 The local MDers had a ball at the time,apparently detecting all night and getting loads of goodies that were lost many years ago.The large bracelet is marked "ITALY" and stamped 325 -1/10- 925 I guess that means it is 9/10ths 9kt gold and 1/10 silver and weighs 6.5 gms.The other  wee bracelet is unmarked but sure has the appearance of gold.The rest are just normal currency (one kiwi dollar and a one pound coin),the watch was an eyeball find and goes great. And two more cars for the stable.
  Most days there are other detectorists on the beach so they do get a hammering in the height of the season.
