Watch the photo report, Mars Goliath coil for Minelab X-Terra 705. Round 15 inches DD.
The rivalry at hunting sites has long demanded not only search quality improving, but also depth increasing. If the search quality with the reasonable approach not to miss dubious signals influences more the number of all for nothing hole-dugs, then the depth gives the advantage just in number of finds. It is achieved by increasing the coil size. The Mars Goliath is an alternative of such large coil for the Minelab X-Terra.
