Hi guys thanks for your responses, Toad yes Whites MXT,Minelab underwater detector Excalibur and gold detector Minelab SD2200d the only one that hasn't paid for itself is the gold one, most i would have found in a trip would only amount to a few hundred dollars.
My cheapest detector is the underwater one, that was $1800 then the Mxt that was $2500 then the SD2200d was $3500.
Great hobby goes well with Photography as you get to go all over the countryside.
Here's my other gold coin a full Sovereign found in chest high water at Como Beach, someone had decided to turn it into a pendant and carve out some religious symbols on it,ruining the coin,pity its now only worth the gold value.
Cheers Raoul
