Yes.
Ingress Protection (IP) 54 is specifically meant for rain and wet environs, as well as dusty ones.
Note that with extended exposure to sprays and splashes...some "Limited ingress is permitted"...but not in 'harmful' quantities.
(It just doesn't like 'jets' of water.)
So, should be perfect for rain...but not for hosing down the detector after a hun

Also, I noticed you had asked the same question in the Golden Sense thread, and I answered (what I hope) was the question you were asking.
To follow-up that answer:
In it's simplest terms, IB (induction balance) is a precise term referring to a constant field method of energizing a field between a primary and secondary (transmit and receive) coil.
That's opposed to a method of send

The short answer is...there's no difference between VLF and IB, within this context.
In this case, IB and VLF are simply being used to distinguish that it's NOT a PI (pulse induction).
See Overton/Moreland's book "Inside the Metal Detector" for more detailed explanation and history of terms.

Rather than writing a lengthy reply, and all the inevitable questions to follow, I first suggest getting a copy of "Inside the Metal Detector" by Overton and Moreland.
It's a wonderful mix of theoretical, practical, historical and explanations of terms...and more.

Tip:
About the only real disadvantage to Li-ion batteries, is that they like/need the chemistry to be frequently 'in-use'.
Other than overheating/overcharging, the worse think you can do with lithium batteries is to store them fully charged and unused for very long periods of time.
(Current best practice, is to store them at between 40%-60% charge.)
I like to say lithium need to

The same reason you don't see AA and 9v batteries in phones, and high end cameras and other electronc gear.
Non-rechargable alkalines are heavier, bulkier, shorter life at high current drains, and quite simply...in the long run, cost an arm and a leg in comparision to Li-ion.
(Lithium also work much better in colder temps where alkalines just give up.)
Who benefits?
The user.

You may (or may not) have been using an earlier X-5 without the later iron mod. (those prior to SN 300)

SN,
Headphones fit my big head perfectly when extended all the way out...with no pressure/hot spots.
Grip feels great to me. Good angle/size. Reminds me of some classic firearms grip angle.

I noticed something that may cause some possible confusion on the MDT...
The metal plate and battery contact spring in my battery compartment's endcap is labeled with a cut-out PLUS sign...implying that the plus side of the battery faces up/outward.
This is wrong...at least on mine.
The battery goes in plus side down. (again, at least it does on mine)
May need to update the manua

Technically, the first was brand new 1972 Jetco Mustang BFO.
But the only coin I 'found' with it was a dime on top of the ground, and I saw it pass by through the BFO loop rather than hearing anything.
Then immediately bought a Radio Shack TR kit detector, and built it. Not sure of model#, but it was brown with a chrome handle and either one or two knobs.
Found lots of junk, but w

Tom,
My 'ears' perked up when you said targeted toward "bad mineralization", full VDI, sensitive to high conductors, and inches deeper than CZ.
I've been waiting patiently for something like this for decades.

As far as battery life goes, I've done two 5+ hrs hunts on one charge and still had a little life left in both devices.
(At least neither device died...and that's with some back-light usage.)

Firstly, no...I believe it's a 25650 Li-ion.
Secondly, even if it were...lithium polymer (Li-Po) is essentially the same chemistry as lithium-ion.
Both systems use identical cathode and anode material and contain a similar amount of electrolyte...one liquid, the

It's definitely in the frequency response, but if I get it balanced just right for my hearing, I can 'force' myself to hear alternating "Laurel", "Gammy".
It resembles an audio version of this famous optical illusion:

If you really want a good scientific explanation by a Neuroscientist, take the 6 minutes and watch this (courtesy of Wired Magazine):

Bey,
I don't think so. I've got very good observation/cognitive skills.
There's no way I can perceive anything other than Laurel.

Tabman,
The trick to passive noise cancelling isn't in the earbud...it's in the replaceable tips.
Normally, I'd recommend a single balanced armature driver (as opposed to dynamic drivers) musicians' in-ear monitor/earbud (IEM) that comes with a wide selection of quality tips to choose from, but those tend to be higher end.

With some price gouging (still) going on, I'd think $969 would sound a whole lot better to most than $1,100 or $1,200.
To each his own, I guess...
It will be nice when they finally get the production sorted/smoothed out.
