    Looks like you're all out of luck and it's developed a fault, if it's out of warranty there is little you can do, fortunately it's not an expensive detector to replace.   Just make sure your coil is done up tightly but there isn't much else you can do.

    As Simon said not much you can do but check all cable, earphone and batteries connections. Let hope that is all it is.

    The crack can be fixed (if you have a good coil and don't want to take a gamble on the replacement being worse) by simply buying a small amount of MEK or Acetone and cutting small pieces from an ice cream container (white of course) or obtaining scrap propylene from elsewhere and mixing the 2 together in a glass jar for a few hours. The resulting paste can be used as a repair glue by forcibly smearing it into the crack, with a smooth over-cover to reinforce. It sets and seals within an hour or two.

    Aureous the paste the you mention, we used to reseal the coil after repairing the shielding in the coils to stick the base and top back together. Always handy to have in your detecting kit when out prospecting away from home.

  3. For those that don't have the good gear or only wants to melt a small amount it is possible to grind a hole in a fire brick and use those cans of camping gas with blow torch to do the job. Pure gold melting point is 1064 most lower purity gold melts at a lower Temperature

    Similar small blow torch

    5 lumps melted total weight 17 ounces

    Some of the course gold, crushed via a dolly,  from a 3½ Kilo Specimen that was melted with the fines.

    The largest melt that the butane would make was about 4 Ounces. I hope this helps those that don't want to get a furnace. Borax was the only chemical that was used with the gold when melting it..

     

     

  4. The Australian Threepence (or three pence) is a small silver coin which was used in the Commonwealth of Australia prior to decimalisation. It is also the same size as UK old 
    Threepence, Coin Type from Australia - detailed information.
    Country Australia
    Size 16.000 mm
      So at 15mm could be OK for most coins but for jewellery have a look at some small ear rings that may occur in you location. Hope this helps you decide the best size to have for your use.

  5. Back in the days of Whites 6000 and Garrett ADS you did not know how to detect on the gold fields unless you could detect one of those pesky little bastard pellet. Once you could you did not waste your time on them and concentrate on ounce plus nuggets.

  6. Just take "NOTE" in RUBBISH AREAS depth is not importance but ID is the name of the game. When you get a signal lift your coil till you get a sound that is distinct at a low volume that is not iffy (this will reduce/remove ground effect and allow more accurate reading). Take note of the ID reading and dig the target, doing this will build up a human data base (yours) of the signals that are the ones you want. Hope this helps and don't think the best detector wins it's the best user that does.
