A lot of bands. Best in the middle: rock 50 pts in 18k, a ban d 18k 7 gr., PLAT 14.3 gr., 18k 11.3 gr. & A Cartier band 18K 7.2 gr. Total 3.9 ozs. I’ve g0tten good results with the CTX 3030 using Andy’s Beach and Jay’s Gold programs and my trusty Dual Field–a very solid and versatile pulse machine.
