Oh, you don't have to tell me...I agree. I've used an Explorer and know what the settings are, though I haven't owned one. But I did own and hunt with a DFX and it has even more adjustable settings. I think the tones are the thing that scare a lot of people off. Like when my sister tried out my Sovereign at the beach...she was practically begging for her CZ back, with it's 4 simple tones.
Me, I like the variable tones of the Sovereign, Excal, and the Explorer/Quattro. There are a lot more settings that are adjustable on the Explorer than the Quattro though. And 54 adjustable settings and I believe 192 tones on the DFX. And for some folks who are "tweakers", they love all that. Me, when I had my DFX, I spent more time tweaking it than I did digging targets. I knew what I was doing...maybe too well. I was spending too much time playing and not enough time digging. That was a problem TOO MUCH freedom to choose and tweak. So I ultimately got a CZ-70 and a Sovereign Elite...two much easier machines to use and a lot less fiddling.
Now the Quattro is something in between. It definitely will have a niche among users who want hi-tech but don't want to tweak, program, save, shift, load, etc. Not that you HAVE to, but some people I doubt get much further than trying to figure out what they are seeing on the screen and getting lost in the menu one time before they get intimidated and decide they made a big mistake. Time will tell, but I think the Quattro will attract a lot of these folks. It's a very nice machine and fun to hunt with.
