Both are good detectors, but a AT Pro is NOT a Minelab and vise-a-versa. I have both the AT Pro and the Minelab CTX3030. The AT Pro is easy to learn and easy to use. The Minelab CTX3030 (like an E-trac) have a much steeper learning curve. If you get a Minelab (they make top of the line machines) be prepared to invest much more time (and some frustration) in learning the machine. I am still learning my Minelab CTX but it; like an E-trac are fantastic machines if; again IF you take the time to learn them. If you lack patience or a willingness to start from scratch learning a whole new language (Fe/Co; bins, programs, modes etc) get something you can handle. Also look at the manufacturers web site and download a copy of the manual (for whatever machine you are considering). This might help you decide your level of commitment to learning a new machine.
