My opinion is this. Look at how much people spend on fishing, 4 wheeling, snowmobiles, and many other hobbies. $1600 is a bargain for a tool to enjoy the outdoors. Just my thoughts😄
The priorities of all are different and that's ok.
Some look at just $$$ and the return of the $$$ the machine can generate.
Over the years I have met my share of folks the sit around their home bundles up in winter wear gripping about how uncomfortable it's in the home, and the lack of food-but the pack of cigs at $15-22 a pack might be the reason.
I don't worry about it a whole lot either.
The thing is if the machine at the end of the arm is producing the finds and it makes them smile-great.
Nobody is forcing anyone to buy anything.
Though as others have said about getting caught up in the hype of the newest widget. I only have to look at the list of machines folks post, and think either they fall into the thinking that the "New" machine will generate lots of keepers.
Repeated over and over, till the stable is full.
Or on the other hand they are so tech savvy that they know each has it's special place for a certain type of detecting they do.
Now that makes me a tad green their ability to understand the operation capabilities so quick.
They old hands (just a term) have a machine that can retrieve a target of let's say 12" for a large cent.
Do they need another machine?

But after 1000's of hours on that machine the only surprise is when they get an unexpected keeper, as they suspected it was the large cent-but it was a real crisp one.
So are the folks that change the phone every time a new model comes out just have to have-or is there a function that will enhance their lives? Personally the need to upgrade a phone is a questionable one at best. (Not what Apple thinks)
After 3-5 yrs a desktop is classified as "Vintage" wow mine is 9yrs old. Worth lots as an operating antique.
Thinking back at the machines that I have used-the machine that replaced the best machines (at the time) some I remember fondly, but the technology today, and the price point of days machines make the one old one seem very expensive.
First good machine in the family was the Whites GoldMaster setting were metal/mineral. Learnt that if we set the machine on mineral and it nulled out-it was metal. The amount of digging was crazy, the depth was amazing, but so was the energy of being young. Example the machine had a hard time picking up a target in dry sand at 2". It sucked. That machine in the late 60"s was $150 and the good 30-06 hunting rifle. (wages were $2.56 a hour)
Then the discrimination model came out, Coinmaster series, Etc.... The price paid for each of these upper end machines were a pricey investment at the time.
So lets take the newest machine at a base price of $1600-is it a ok or expensive price?
It depends on the individual and what one can put in the pouch at the end of the day.
