XP ORX VDI Numbers - US Coins

[eman1000]

I've got a couple hunts in with the ORX and so far I'm liking the simplicity of it. (Pretty close to what I would call a multi-tone Tesoro)

I haven't dug anything >6" on my hunts yet but air test are impressive.

Mens Wedding Band (small) 57
Vnickel 60
Clad Nickel 62,63
1/2 dime 80 (impressive solid vdi # at 6" air)
Indian Cent 84-86 (Dug an 1881 today with the ORX at approx 6")
Memorial Cent 86
Lincoln Cent 86-91 (Older pre 1981/82 ring higher)
Wheat Cent 91
Dime 91 /92 (Barber was a solid 92)
Quarter 94/95
Large Cent 95
Dollar Coin 95
Ike dollar 97

Pull tabs so far vary but had a few that fell in the Nickel range
Bottle Caps - I haven't hunted where there are bottle caps yet but tested a few and there is a distinct audio difference depends on orientation (similar to a Tesoro almost like you can hear the ridges of the cap)
* I would probably dig them as they are solid 94

I dug a few bullets today that rang up in the mid 80's and a few pieces of odd aluminum/iron pieces at an old school house that hit in the 90's but that's to be expected.

I hesitate to give a full review after just a few hours. The only real issue I had the first couple of days is some difficulty pairing the headphones (I have found if I turn the machine on first it prompts you for audio and if I hit x, then pair the headphones it seems to work on the 1st try)

I haven't done any nail board testing but so far no issues with coins on edge in practice. Let me know if there is something you would like me to test or film.

Thanks for posting this Eman. I just purchased one of these last night and was wondering about the TID of US coins and such. There just does not seem to be many guys using this unit here in the USA and I appreciate you posting this.

I started a thread on another forum but since you seem to be active on here I will ask here. So here are a couple of questions. Where does iron stop on the VDI scale and non ferrous begin?

which machines were you swinging before your ORX and how do you compare you ORX to them?

From what I can tell on youtube videos this ORX seems to have a very fast recovery speed.

Does this have a depth meter or running depth on the ORX?

I have several machines already and am looking to get it down to about 3. Any and all input and thoughts are welcome. HH, Tim

I do not have an ORX but have had the Deus for two years now and am a coin hunter in newer, trashy parks. Yes, crown caps sound like a quarter, but there is a way that can help identify the nasty crown caps. On the Deus, I allow an iron volume of 3. This way you can wiggle the coil and draw it towards you and as the front edge of the coil passes over the target, a bottle cap will (most of the time) give an iron grunt. This grunt can be very subtle, so listen carefully. Also raise the coil 6" or so above the target while swinging over the target and if the TID drops quickly, it is most likely a crown cap. As I said, I do not have an ORX, but it should operate like the Deus in this matter.

Where does iron stop on the VDI scale and non ferrous begin - Yeah the manual is not real clear on this so I will have to do some testing and get back to you. I marked about 20 spots in my yard last night to dig and some were around 30 on the vdi that were not giving an iron grunt but a mid tone. I haven't dug any keepers yet below 50 (I was listening to a podcast where they talked about disc up to 50 and you can still here the iron grunts - I imagine this would be sufficient for gold jewelry and coin shooting)

Machines I had prior are a long list, but I had the equinox and it is as fast if not faster than the Nox and the depth is nearly equal, but this is using a 9" coil in comparison to the 11" on the Nox (I personally wasn't a fan of the tones on the nox or the vdi scale but that is personal preference)

My MX5 is also very fast recovery but not this fast. (I do like the whites tones and vdi on US Coins) For the longest time I thought the Tesoro Vaquero I owned was the fastest, lightest, and deepest machine I had but I now give that title to the orx. If you take the control box off the orx and put it in your pocket it is like swinging a stick it's so light. Also Tesoro's have incredible ability to unmask targets which is different than separation (which the Nox is excellent at) so I look forward to hunting some really trashy spots to see how it performs.

There are some negatives though - (First the manual - is basic! a little more depth and some color pictures would go a long way) I watched you tube videos just to put the coil on.

One is the pinpoint mode is not ideal to operate in my opinion you turn it on and off with a 3 second delay unlike the MX5 which is instant but you do not get a depth reading where as on the MX5 you get a depth to a 1/2 inch. I would have liked to seen that as a feature or update - However with the 9" coil it really isn't necessary as you can use the wiggle method just fine.

Three tones is also probably a negative for some as you really have no audible difference between a penny and a quarter (A nickel falls in the mid-tone) and you cannot adjust where these tones fall.

Waterproof & Multi-freq (The waterproof is a deal breaker for many but I don't really hunt in the water and if it rains I can use a ziploc bag, still I would have preferred the control box to be rain proof or come with a cover). Being able to see what each freq is doing on the V3i is an awesome feature but it also weights 5 times as much and that is a problem for me.

The menu is a little basic (for example if you scroll past what you want you will have to scroll all the way through I don't think you can go back up) - Minor complaint as there are only maybe 5 or 6 sub-menus but still...

No Depth meter - This is kinda minor for me because the audio is so good on this machine you can feel the depth (sounds weird but trust me you can lift the coil and almost call it within an inch or two)

Another thing is I'm 5' 7" and I couldn't help but think if you were a really tall guy an extra stem might be needed to extend the detector further (not sure if any Deus owner have run into this or not)

I haven't charged it yet so I am curious to see if that is an easy process.

Hope that helps. HH Eman

James, I will check the iron volume out and give it a test on the bottle caps Thanks!

Yep, the wiggle iron tone trick for revealing bottlecaps that James uses works great. Also note, that at lower reactivity settings (1 or 2), silencer filter is cut in on the ORX in Coins Fast mode (silencer is something you can turn off on Deus, and I do but you can't on ORX in coins fast. Based on what XP has posted, we are pretty sure silencer is disabled altogether in Coins Deep mode but not 100 % on that as they are a little unclear in their descriptions). Anyway, silencer will tend to break up the bottle cap tone noticeably, so that is another trick. The downside of silencer is that it can tend exacerbate masking of targets in the proximity of iron because the silencer will attempt to "silence" the iron tone and that will interrupt the nearby non-ferrous signal, similar to lowering recovery speed.

The default silencer/reactivity correspondence chart (applicable to Deus and ORX Coins Fast) is as follows (higher silencer numbers equate to more silencer filtering, "-1" corresponds to silencer filter being "off"):

Reactivity/Silencer

1/3
2/2
2.5/-1
3/-1

So on ORX in Coins Fast you may be subject to more masking at reactivity settings of 1 and 2 (but these will also tend to break up bottlecap tones too). Pick your poison.

Thanks Eman for going into some detail on your input of the ORX so far. Yes I once had the V3i and Vx3 both plus a ton of others. But that spectra graph thing Whites did on the V3i is very nice. That was the only thing I really enjoyed on that unit. I went back to the MXT after a few rounds with those V3 units. Not knocking them or anything but I kind of got lost setting it up somewhat and would rather just detect. However, the anfibio has so many settings as well, that you can find yourself getting into the tweaking aspect to fine tune it so much it is almost an overkill too. But it is a good unit.

I see you say you think the ORX gets as good of depth as your equinox does with a smaller coil. I saw one of the videos Calabash did and could tell it seemed to get good depth. I was surprised with that and I like that too. I think the ORX will be a little easier to swing in the woods with the 9" coil. I have been searching the woods here lately with the 11 inch coils on the equinox and anfibio. So I believe that will be a big help having a slightly smaller coil size but it's still a good decent average coil size too being a 9 inch.

I posted the iron TID scale question on another forum and here was one of the XP reps responses I got on that, I am posting this here so this may help you a little too. In quotations below,

"Iron rejection tops out at around 10, as with most machines large mis-shaped Iron will very often break through as a good tone but on the ORX/Deus Will give a low buzz and inconsistent numbers.
I run my ORX Iron rejection at 5.5."


So with that being said, it seems to me that nickles should pop up around the 30's range but on your testing nickles pop up in the 60's range.

I find that a bit odd. Maybe the XP company really opened up the low mid range area into a longer spectrum for fine gold since the ORX seems to be oriented into the prospecting world as well and small nuggets fall into that range. I do not know just a guess.

I also like how it has an external speaker in the housing or pod or whatever it is too. I do not know if I am going to fiddle around with the wireless headphones but having the ability to plug in a small set of headphones and placing the control pod into a pocket or whatever, I think that is a cool feature. Plus if your out and it starts to rain, you could just place the control pod into a pocket as well and keep on swinging.

Anyways, looking forward to it very much.

The VDI numbers for ORX are normalized to 18 khz (the same as Deus if you use "ID NORM ON") independent of the actual coil frequency. The Deus/ORX coil frequencies range from ~ 4khz to as high as 78 khz for the HF elliptical coil. Target ID numbers for non-ferrous high conductors tend to get compressed up to the top of the scale as you increase in frequency from 4 khz because the scale is always fixed from 0 to 100 and is actually circular continuous (I.e., wraps back around once you get to one end or the other) because it really primarily represents a phase angle from 0 to 180 degrees. For comparison, the Whites detectors discussed (V3 series and the MXT have operating frequencies around 14 khz on average (I know the V3i is multifrequency, but the highest frequency is 22.5 khz and the mid frequency is about 7.5 khz, so Whites VDI is probably normalized closer to 10 to 14 khz for the detectors mentioned) which would result in less compressed VDI's compared to ORX across the scale. That is why the numbers seem pretty high for the non-ferrous targets. Ferrous VDI does not vary much with frequency so it will still hang out around the single digits.

If you have Andy Sabsich's latest Deus Handbook, he lists the following coin VDI's for 18 khz on Deus which should also correspond to the ORX VDIs (again regardless of the actual coil frequency being used since everything is normalized to 18 khz):


US Nickel - 64
Large Cent - 94
Wheatie = 91
Indian Head - 85
Zincoln - 85
Silver Dime - 91
Silver Quarter - 94
Silver Half - 96
Silver Dollar - 97
Pull Tab - 81
Beaver Tail - 73
Ball of foil - 34

Expect gold jewelry to fall anywhere between 50 to the 80'S depending on shape, mass, and composition.

These are pretty consistent with eman's numbers.

In other words, the nickels are popping up right where you would expect them to pop up for a Deus running at 18 khz, i.e., around 60.
