G2 great detector
I been detecting for 30 years plus, used most detectors from low to high end, my main detector for field hunting was the T2, my back up detector was the G2. I took the time to learn the G2 well, working iron infested areas with great success finding old silver coins and some nice gold rings.
I find it to be a great detector in the trashiest of ground, working slowly and becoming familiar with its sounds and target ID. Is the KEY. There are detectors that go deeper, there are detectors that are built better, and there are detectors that have a great deal more electronics but, here's the facts, few if any metal detectors, are lighter, easier to set up, go's deeper on gold or silver coins with good discrimination, for around $700 dollars than G2.

If you take the time to learn it, you can compete with a lot high end detectors, when I get a good signal in iron infested ground I call my detector friends to scan there search coil with there $1500 dollar detectors over the target area and ask them what do you think? Lots of times they will say IRON !!!
I dig it sometimes there right but, many time there wrong. The other day I pulled a barber dime they checked, Iron they said, "wrong", later in the hunt a V nickel, after they checked, "Iron" wrong again, a three cent piece, three mercury dimes and silver halve dollar to which a $1500 detector didn't pick-up because it was on edge and in old cinder or coal dump area, so here's the deal, I know this isn't the best detector money can buy but, for me the G2 is-NOW- The first detector I grab on my field hunts, my love for this detector will only last as long as it produces, but for now coming from a treasure hunter who used a lot of detectors, I can't argue with success, for me the G2 is a keeper.
I make no recommendations, I'm just telling you my story. Thank you!

CZ7a - fast, easy, all around detector
The Cz7a has been a real treat to own and use. I have found like all machines you must get to know it for it to be of any use. Once you know how to operate and use the fun begins. I have found things such as a buried womens purse with gold necklace inside (20 years buried)at 5 inches deep, gold ladies ring (gave foil signal)lost at park, owner found, 1876 Indian penny, old military buttons,at a road construction site 7 inches deep,1916 lincoln Penny at 8 inches deep, all around detector.

Time + knowledge = finds with this machine. Like others have said, you will always dig trash to get the good stuff. Pick up a used one and try the notch buttons on the touch pad screen to just look for coins, or release to pick up the signals for pop tabs and foil when at the beach,might just find a ring or two, use in salt water or fresh, with the 7a pro you can detach the box and wade up to your butt in the surf. Do the research, grab your CZ 7a and go have some fun. Best fun for the money spent. If all you find is modern coins until you get more experience take this money and buy a coin or gold that will grow in value.We all have our own learning curve. I have come home with rashes on my legs from carrying the coins in my pants pockets found with this machine. Buy one and take your grandchildern "treasure hunting"

You will always find coins with this machine. You will find rare coins, you will find jewlery with this machine. Best of all you will find fun. I have the CZ7a and the CZ7a pro. I do not work for Fisher Corporation, Enjoy!
