I don't remember how many detectors I've owned over the decades but I curranty have three that I use, plus three loaners. I don't think it's fair to compare any of the currently available detectors to older models since today's technologies are far superior to anything from years past, even for entry level detectors.
I can only add that with both the Deus 2 and Deus 1 there are more customizations available than most owners will ever utilize to their fullest potential. You can look at these various combinations of multiple adjustments as a way to create different detectors, each suitable to different situations, to a much greater extent than most other detectors. Then add the extremely fast recovery speed in simultaneous multi-frequency on top of this customizability, plus its light weight, being waterproof, with depth equal to all the major players--this is why the D2 is my number one choice, with the D1 being a close second.
But I have to say the Deus isn't for everyone. It takes learning. If you're not willing to put the time in to learn all the adjustments and customizations you'll be paying for feature you'll never use, and these are not inexpensive machines. You certainly could just take it out of the box, turn it on, and only ever use the preset programs and it's still a great machine. But you have to decide if you mind paying for options you'll never use.
