I'm a newbie to detecting. I decided on the Quest 30+ over the newervNokta Simplex, simply because of the deal that I got on a detecting package. Honestly, I was about to flip a coin, when I found the Quest on sale.I made a list of Pro's and Con's when deciding on the Quest. They pretty much washed out. But, the Quest seems to consistently detect much better in mineralized soil and salt water than the Simplex. Quest is better known in the UK than the US, where Nokta is favored.I finally got the chance to go detecting for the first time a week ago, in WV, on the top of a mountain, at the home of a friend. This is a target rich environment, and I fully expected to find all trash.I put the detector into "Park" mode, so it would detect practically everything. The hard clay soil was extremely dry. I wasn't sure how deep it would detect in the heavy clay. I had to stay 3 feet or more, away from the garden fence. It wasn't long before I heard a signal.I detected a medium strength signal. With the help of a pinpointer, we dug approximately 6" deep before finding the pictured meteorite! This is an iron-stony meteorite, and it's very small, at around 1cm. Our friend had found a larger specimen on his land a few years ago, so there was the possibility that it had shattered on impact. I'm an astronomer and I own a much larger specimen.I was very impressed that the Quest q30+ had detected this little meteorite. I only spent an hour detecting with the heat being as it is this summer. I found 3 modern pennies, 1 old gate latch, 1 old bottle cap, 1 chunk of an iron something, a piece of a buckle, and a shell casing. In other words, junk, except for the meteorite. But I'll go back, because this mountain had a lot of very old homesteads. I just detected one small area. I know where other 200 year old buildings once stood.I'm sure it's capable of detecting quite deep. The signals are loud and clear. I have everything to learn. I have one complaint; the buttons are all black on a black background. They're hard to see. There are 2 buttons on each side that are hard to see. I wish they had done something different, to make the buttons easier to see.I have Bluetooth headphones, which readily connect immediately to the Quest. They are NOT Quest brand, so I can tell you that the Quest works with other Bluetooth headphones, provided they're 2.4ghz.As I keep detecting, I'll update this review. You get a lot of bang for your buck with the Quest q30+. I didn't want to drop a grand on a detector as a beginner. This seems to be a good, middle of road detector, with a lot of features found in much more expensive detectors. The entire detector is waterproof to several meters, it has 6 modes, including 2 gold modes, and a salt water mode, wet sand, park, and field. It had 100 levels of discrimination. It has a frequency shift in case of emi. You can adjust the sensitivity of iron separately from general sensitivity. These are just a few of the programming choices that you are given.I'm disabled, with Parkinson's and hardware in my back. I found the Quest easy to use, and lightweight. It's fully rechargeable with the included magnetic cable. The instruction manual is clear and understandable. I keep a pdf copy on my phone. Quest has an app that connects the detector to your phone via Bluetooth.
