With the little experience I have with the new machine, I am definitely noticing more frequent signals on targets that are 5+ inches deep.
Of course there are all levels of detectors. And one would hope that the more expense put into one is at the very least giving something a bit better than the cheaper ones. The old Cadillac vs a Pinto Fry-Baby sort of scenario.

LOL
I didn't ask to start a rhubarb just that even I recognize that are stronger/deeper/better discriminating detectors than what I use. I too am considering an "up"grade somewhere down the road. I bought what I believe to be one of the very best "ALL_ROUND" detectors to start my "new" career. I knew it was perfect for what I had planned. AND...for these last 4 years or so, it has done EXACTLY what I demanded and expected of it.
Thing is, that where I save in expense I also lose a bit in sensitivity/depth. Some of the places I hunt, I strongly suspect, have MUCH more to offer! I believe that just maybe, I'm at a limit on the depth I can search. Wishful thinking? Partly.

But, as I expand more into my lifetime hobby, I'll be watching and listening to everyone's comments about their "new" machines. I'll also be milking the experts' minds about what to expect from ANY machine and WHY!?
For you see, unless I do find that 20 karat stone, or that 20 dollar gold piece cache, or that super, ultra rare coin, (like an 1856 Flying Eagle cent that was kept in a vacuum sealed mason jar). I won't be buying anything for a while. Now, rent/borrow/test drive etc, isn't out of the question. Just won't be buying until I can AND....I have a clear understanding of why to pick the one I go after.
All that said, one thing I have noticed in this hobby over the last 40 years is that some wonderful finds turn up when someone gets a new machine. And it's usually because with the learning curve there's some doubt and each tend to listen much, much more carefully. AND, that, will cause that effect on ANY detector, even the old one. LOL
Thanks for your help!
