You know I can't jump in and tell you when you figure out some of the features and functionality of the CTX 3030. I'd like to, but I can't. However, I will say that a couple of you are getting a good feel for what this detector represents. It is going to be interesting when the curtain is pulled back and you can see for yourselves what it has to offer. Some of you are going to smile with satisfaction as you see how close your speculations resemble the specifications. Others are going to scratch their heads and wonder how they could have been so wrong about so many things. Yep, it's going to be interesting! HH Randy
