This is a modified Cobra II (mods done according to instructions provided by the original designer)with added GB (20 turn), threshold, V.sat, & dual AM mode controls. It is in decent condition & comes with 5.5" & 8" coils. It is an ultra sensitive detector re. low conductors; it can easily pick up a 1 grain gold nugget even in disc. mode. It has a variable notch, 2 tone audio & a hipmountable control box. I was going to use the Cobra for prospecting, but managed to get a GMT (White's top of the line nugget detector), so decided to sell. The Cobra II is essentially a rebranded Treasure Baron &, modified as this one is, is essentially a TB with the Prohunter module installed, but with some added capabilities. A little research will show that the Barons are extremely deep detectors. The price is $295 US which includes shipping in N America. Email me for more info & pics or just reply to this post (it will be sent to my email addy). ..Willy.
