After doing quite a bit of research I decided to purchase the Delta 4000. Due to busy work i had to stop Metal detecting almost 30 years ago so my ADS III got retired. The Delta is an amazing detector. I visited a local ball park to get to know how to run the Delta. After seeing a couple other "detectors" at the same park I went to work. I'm still not done with the park but so far have 25 Quarters, 28 dimes,12 Nickles, and 3 of the 38 pennies were Wheat!!! Pinpointing is very easy as most of the time I'd hit the top of the coin with a brass probe. with some over 7" deep. I can't compare to others on the market as I haven't tried them but at this point I see no reason try.

Teknetics Delta 4000 great machine and best buy for the price range!
This is the first detector I ever had. My wife got it for me for Christmas three years ago. The Delta 4000 has Pro features you will not find in any other machine in this price range. Simple to use and easy to learn. Hands down the best detector in this price range! Features include discrimination, notch, pinpointing, and volume control. Best bang for the buck and also this model has several coils you can get that will work with this machine.
