decision!!! I was ready to buy one when a friend of mine , suggested that it is a poor choice for gold ring and jewelry hunting!!! ( The kind of hunting I like) He says that the 6.5 Khz frequency is hot on silver not good on gold. Further more he says it's an " arm buster" and that it's balance is poor. I had located and arm rest for the CX plus but he claimed it does very little to help. I have the Gold Scorpion but I'd like a target ID unit that is simple to run. I thought that I had settled on the CX plus. Now I'm not so sure ??? I need tips and help from people who have used this unit. Is it hard on the arm?? Is it not a good choice for park and field ring/jewelry hunting??? Guys.....help convince me to get one..........thanks for all your replies.
