Hello Grizz12, welcome to the Site, Tnet that is! "Just getting started in detecting", how well I remember that status! In about 1965 I would find a new article on how to build your own Beat Frequency detector in an electronics magazine and not long after would have yet another detector that would find ALL metals w/o being able to tell the difference between them. Then I borrowed a fellows machine, a Whites 6000D Coinmaster, I never built another detector from an article again.
Todays machines have come '"Across the Universe from 1965 machines", they are quite amazing. Each of them has its own learning curve and capabilities! It all depends on what you will be looking for and where, both of these are important to understand to be able to understand what machine to purchase for your purpose And Geographical area.
Towards the top of the Tnet page you will find Brands and models discussed which may be interesting for you. Possibly you may want to locate the nearest Detecting Club in your area. In the Anchorage area is a large Military Base, the 'Airmen' tend to move in and not that long afterward move out. When they move out they tend to sell off a lot of household items and maybe, this is likely a real stretch, just maybe one of them may want to get rid of a detector. Might be worth checking out. Of course you will want to know how useful any given machine is for your area so it could be more work than its worth.
Also in Anchorage there is a prospecting shop, I think it is likely they are still in business, and I'd expect there would be a few different dealers in that general area of Alaska.
Yup, you've a lot to learn Before you purchase a machine otherwise you could waste your money and that is not a good way to start.
Best of success with your searching and learning...................63bkpkr
