The Fisher F-70 is a very easy detector to use. I have been used to using a 1991 White's Eagle Spectrum and compared to that, the F-70 is a dream. This is a turn on and go machine.
The F-70 can be adjusted to most hunting that most people do. It is excellent for coins, great for relic hunting and from what I have heard, a very good gold nugget hunter.
I love the light weight of this machine. Under 3 lbs. it is one of the lightest machines out and very easy to swing all day long. It is great for the older folks with arthritis and great for youngsters also. The ergonomics are very good and the machine is very comfortable to use. The screen is fairly large and the numbers are easy to read even in direct sunlight. The recovery speed is awesome which is great for trashy areas.
The 4 AA batteries last an amazing 40 hours or even more. I run 2650 MHA rechargeable batteries and I can go up to 65 hours until I get a low battery warning.
I do a lot of coin shooting and the F-70 is so good at finding coins that it is scary. You can swing very fast and cover a lot of ground with the F-70. Depth is excellent with many coins found at depths of 10 to 14 inches depending of ground conditions.
There are a few coils that are available for the F-70. Any coil that can be used on the F-75 can be used on the F-70. My favorite is the 6 inch coil that is excellent in trashy areas like parks and school grounds. Several modes of operation are available and the F-70 can be adjusted to just about any conditions.
I have found several silver rings, a few gold rings and tons of coins with the F-70 in the 3 months I have owned it. More rings and coins in such a short time than any other machine I have ever owned so far. I would recommend the F-70 to anyone who is looking for an under $750 machine that performs like an above $1000 machine.

I love my F70. It is so light and balanced. It is my second detector and a big upgrade. I put the F75 coil on it and I found a dime on edge at 5 inches down. I usually hunt for coins and jewelry. I wanted a detector that wouldn't hurt my arm because I have a small frame. Also, I enjoy the sounds much better than my other detector. I like the big number reading in front of it too. I am looking forward to finding deep targets at the beach. My other detector doesn't have ground balance but this one does! I highly recommend my F70 to anyone. The price is affordable too!

I found that the detector has a learning curve but once you use it for a few hours it becomes easy to use. The most I like about the detector is the depth it gets - it gets great depth on all coins and it id's them pretty good, also the built quality is very good. IMO, I'm into coin hunting and so far in three weeks I've hunted some hard hit sites and managed to pull 20+ wheat cents 30 some coins, and a mercury dime. I'm still learning it a little but so far it is a good machine. I'd recommend this detector to someone that has used another metal detector before. I would not recommend starting out with this detector because it can become very confusing with all the settings. I would suggest that if your getting started into the hobby to look at the F2, Garrett Ace 250, or a Technetics 4000 because these are a much easier machine to start with then once you get the hang of one of them for a while and are looking to get some deeper finds get this detector... it's awesome!

I've been using older and home brew detectors for 40 years. I decided to move up and try the F-70. This one had been upgraded to the 11" DD coil. When I first tried it I thought it was broken because it was so noisy. I soon discovered I had missed so much stuff even in my own front yard that it wasn't lying. After a little tuning and learning to walk past the 100's of pull tabs and foil wrappers in the parks around my house, I was busy filling my pockets with coils & other items. I only have about 16 hours on it so far (1st batteries are not even showing any wear yet). I have 124 coins, 18 bullets & a brass fire nozzle. It can separate coins as close as 2 inches apart. Before you move to pinpoint mode, it can usually zero within an inch or two. After pinpointing, I can usually slice in and get within 3/4 of an inch of a coin. I pulled a 1945 mercury dime at 8" deep. The only place I haven't been able to use it much is below nearby metal bleachers. Within a foot or two it gets a little overloaded. I'm still experimenting with the settings but may have to move to a 5" small coil to get in close to the metal footings. Walking fast is not a problem with this detector. It will cover the ground. It just finds so many coins. I can't get very far.
This machine is awesome!
