What is the difference between the Bullseye 5.3 and the older Blue Max 600? They will both work with my old 6000/Di Pro SL which operates at 5.69 hz? I have been away from treasure hunting with a metal detector for over 20 years but some of those old diseases
come back! I have been operating the 6000 SL for about 2 weeks and have dug over 200 coins with it. It is quite an improvement over the old Garrett Groundhog which I still have.
