I started having wrist problems. The problem was with the Pro-swing harness, or I should say my setting it up. put the Velcro hook below the hand grip. Thus the detector was tilted just a little bit and I guess my wrist was constantly applying a little pressure to keep it level. Wrong setup. I move the Velcro Hook on the shaft above the hand grip and problem solved. At my age, without the pro-swing harness, I was good for 30 min on the CTX3030. If they came out with a version of the CTX3030 with the light weight of the XP Deus, it would be a best seller in my opinion. Probably the best detector for finding deep silver in urban areas like Atlanta with lots of modern trash. Well that is my opinion after coming off 3 years trying to make the 800 do what I needed it to do. The 800 is not very good in an urban area with lots of modern trash. Beach, out in the country hunting relics, gold in the desert a way from modern trash, it is one of the very best detectors you can buy.
