You can't compare the feel of the CTX 3030 to the E-Trac whatsoever. The CTX 3030 is perfectly balanced and is a pleasure to swing. I have a bad back and so it takes me all of 20 minutes to figure out if I will have problems with swinging a particular detector or not. The E-Trac would start hurting my back very quickly and so I used one of Doc's Swingy Thingy's and it solved the problem. I have swung the CTX 3030 for a total of about 15-20 hours now and have had zero problems with my back. The balance is really great and I guarantee that if you didn't know that the CTX was heavier, you would never know it. This is a cool machine and I am starting to like it more in the last few hours of use then when I first started testing it. This detector is growing on me, that's for sure. A couple of days ago I didn't know exactly how I felt about it, but after using it all day today, I have to say it is certainly proving to be a major contender. Hope this helps. HH -Marc
