I would like to trade my mint condition Teknetics Mark 1 Limited for a similar condition or lightly used Wilson ATD or R & C series(early 1990s) metal detector. My Mark 1 LTD has the depth mod,heavy duty battery clips and converted to a hipmount. Included is the long cable red 7.25" coil with cover. Works and looks like new. I might even consider a Fisher CZ-6a,5 or even a current metal detector. Just ask.
