Well, here's my opinion ...
I've used my Deus for the last 7 years and my E-Trac for the 7 years before that.
I'm a coin & relic hunter - I only Beach hunt one day a year at the most so I'm pretty sure I won't be getting a Deus 2.
For those of you that hunt the wet areas on fresh and salt water beaches a multi frequency machine is a must have.
From what I've seen and read the Deus 2 could turn out to be the best multi purpose metal detector ever made.
If the Deus 2 is as good as they say - you'll no longer need to have two different machines for Land & Beach hunting.
As far as the cost of the Deus 2 ...
Multi frequency & Waterproof down to 60 ft. plus - I'm surprised the cost is not higher - $2000.00 or more.
Look at how many thousands of people spent $2500.00 on their CTX's.
Metal Detecting is one of the most affordable hobbies on Earth once the initial investment is made.
The cost of buying a high end metal detector, headphones, pinpointers, diggers, etc. is $2k to $3k.
The life span of most of this equipment is 8 or 10 years or more - and gives you many thousands of hours of use.
As other's have already posted - $3k won't get you very far in other hobbies like ..
owning a Boat, racing a Four Wheeler, restoring an Old Car, buying a Harley, playing Golf, etc.
I use to spend well over $10k a year on Ship Wreck Diving - that was 30 years ago.
The bottom line is ... over time, our hobby is very inexpensive for the money we have to invest.
It probably only cost me about 10 Cents an hour (+ gas & 9V batteries) to hunt with my E-Trac & Deus over the years.
So, buy the BEST metal detector you can - you'll find a lot more and you won't loose a lot of money on upgrading !
Good Hunting !
