Air Metal Detectors, a machine that uses your cell phone as a passive remote, is now a reality. It has existed in prototype form for years now, but has finally entered production and now is in the hands of some backers. Backers of its Kickstarter campaign will be first in line, so it may be months before the general public can get our hands on one. Below are some photos of an unboxing. Instantly it reminds one of the XP Deus in many ways. It also functions similarly with the main hardware stuffed in the coil while your phone replaces the remote. This unit is around 7khz if I remember correctly, so it this model is neither selectable nor multifrequency, but the inventor has said he plans for his next machine to be multifrequency. This machine faced many hurdles before the inventor was finally happy with it. So it will be interesting when the first reviews pop up. What do you think of the concept?
Saw this posted. Detector delayed due to virus being reported. Think you got to be a member here to see entire thread. If what is said in thread turns out to be true, detector will have some nice features.
Seems Garrett is going to market one of the what was White’s gold VLF detector models soon. Don’t know which one though.
One of the things I like most about VLF's is their target ID's. I'm amazed with detectors being able to ID targets. Where I hunt I prefer to dig as few holes as possible so I heavily rely on Target ID's. My front yard is the most difficult place around my area for coin's to ID well, it has the EMI of my house nearby, the worst seems to come from my long range wireless router, I'm also abut 100 meters away from some high voltage power lines that carry power from the nearby windmills to the town. Once away from my front yard the results of this test do not change much, the ones that shine in this test are even better away from the EMI and the ones that struggle in this test while they do improve their overall performance ranking on Target ID's doesn't really change.
What I've done with this video is tweaked the detectors the best I know how to handle the EMI with as high sensitivity that keeps them stable and gives their best hope of a good ID, some run fine maxed out in sensitivity while others needed high disc to operate. If I lowered the sensitivity anymore on the ones that are struggling with the EMI they would no longer detect the deeper of the two targets so I have to allow some EMI interference to get that deeper target.
I've put white rocks on the grass where the two targets are located. The target on the left side is the deepest at about 8" while the right easier target is the same coin at about 6". They've been there around 2 years. Both are NZ $1 coins.

Edge thickness (mm)
Not all detectors are running equal coils, this is part of the equation of course on how well they perform. While the bigger coils get more depth and can accurately get ID's often better than the littler coils they do suffer more from EMI and also on the deeper target they're often more affected by the nail that is about 4" in front of the deeper of the two coins. The entire area of lawn is covered in roofing nails from when the roof was replaced some years ago. The roofers just throw nails down all over the place while removing the old roof.
So this test wasn't to say some detectors are bad or good, it was just showing why I like certain detectors for hunting in my conditions around here, and why I think some excel over others in these conditions with the coils that I have for them. Each have the coil I find best out of the coils I own to suit this test. If I put smaller coils on some of the detectors they are unable to detect the deeper left target at all for example the 6" coil won't see the left target on the Nox at all.
If I had to rank these detectors out of which will give me the best target ID's in the soils around here I would rank them as follows:
#1 Vanquish so very close in performance to the CTX/Nox but just that tiny bit better as the Vanquish handles EMI the best.
#2 Equinox / CTX 3030 are so close in performance I'd say they're about the same, although I have very limited CTX knowledge so far being very new to it.
#3 Ace 300i (In this video it suffers the most from EMI but get it 100 meters away from my house and it shines with good depth and ID's ONLY with the Tornado coil giving it the #3 ranking)
#4 Gold Bug Pro / Detech Ultimate combo, change back to any other coil I own and it's performance drops a bit.
The AT Gold, and Teknetics T2 come in at the bottom, I'm not yet sure if the AT Gold is due to the smaller coil size or not, I only have that one coil for it, the T2 is a depth monster but it's ID's are poor by comparison I think, and the smaller coils on the Vanquish and Equinox easily give more accurate ID's on the shallower of the two targets than the AT Pro and even in the best conditions its ID's are nowhere near as accurate as some others when targets get deeper.
Now please don't read into this in any way that I'm bagging out certain detectors or something, that's not my intention and while the T2 might be at the bottom perhaps in other conditions it might be on the top, I do not know. The AT Gold I only have the standard coil for so it's instantly at a disadvantage. What I'm doing is showing why I prefer the detectors that I do for the conditions I hunt in for my coin hunting where I rely on Target ID's for dig decisions.
This video really shows why I like the Vanquish so much around here for coin hunts. I'm looking forward to learning more about the CTX it seems very promising and is doing well on silver coins in my local spots so far. Sorry for the Ace section, at 1:05 I switch to the deeper target, I was too close to the screen with the video so it is hard to tell when I switch targets, especially with the Ace giving similar ID performance on both targets.
What stands out to me is I could tell a local person hunting in my area if they just wanted to find a bunch of coins and some rings or something without spending much money they could easily just buy a Vanquish or an Ace and do quite well, and not really be left miles behind over someone with something like a CTX, keeping in mind once you're away from my yard junk levels go down to next to nothing, iron junk is very rare in our parks and sports areas around here, with the main junk being bottle tops and pull tabs, and low value coins 🙂
Obviously this changes for people with very high trash or different soils or whatever variable makes it invalid.
This woman goes detecting in high heels 🙂

People have been metal detecting since 1881, when Alexander Graham Bell invented a device to find the bullet lodged in President James Garfield.
But it took several more decades for recreational metal detectors — devices that resemble “sort of a skillet on the end of a pole,” as one newspaper put it in 1927 — to develop a serious cult following.
Now, that cult following is growing. Detector makers are reporting record sales. According to an annual report from one brand, Minelab, in 2020 the company sold 30 percent more detectors than the previous year, which had climbed 18 percent the year before that.
And we are in a bit of a detectorist media moment. New York magazine is making listicles of the best metal detector models. Drew Barrymore is giving them away on her show. The teenage sketch comedian Parker James is wielding one before his six million TikTok followers. In England, Carey Mulligan is making it mainstream; on Nantucket, millennials are making it fashion; and in the gaming industry, a romantic thriller-meets-metal detecting video game will be released this summer.
