I tested 50 gold pieces, rings, pendants and anything gold, with the Equinox 800 and the Deus 2. The Dues 2 numbers were jumpy just by two or three, but it did sound good on most. The Equinox hit strong on everything with a solid number. On odd shaped and small objects of gold even a small gold chain the Equinox sounded much better. Both were in Park. Why?????
