The number 46

[Idaho PRB]

I have a problem with the VDI #46. I seem to remember someone saying that they dug a half dollar or something that gave a solid 46 on the VDI scale. The halves I have found have been 44, quarters 42, dimes 38 to 40. I have found quite a few nice targets that never showed a single 46 number even when the VDI number was jumping around a bit, on the flip side I have had a lot of good high signals that showed the number 46 even once and all ended up being junk. I guess I'll quit rambling and get to the point, I have never dug a single good target that registered a 46. Am I really screwing up by eliminating this number from my must dig numbers? I'll add that I'm not a relic hunter, I'm talking about coins and jewelry. My soil usually GB's 17-24 and I run DD coils too, if that might make any difference in the equation. Thanks everyone!

that will read a 46.

I get the same kind of GB numbers here in Spokane. I would dig 46 every time. But... what happens when you go to AM or Pinpoint, does it turn to iron? My 46s usually turn out to be a jar lid or some similar junk. I would kick myself for not digging a Half or a Silver $ and hear that a friend was on hte same lot and dug the same spot and recovered MY half.

I have dug up a chunky silver ring at 46...

Check it out at the video below (go straight to 4:20 if you like)

When using the small coil, a silver dollar will give you a 48. If you use a pattern with 48 null-ed out, you will miss a silver dollar. I have tried this with a silver dollar on the ground and was amazed.

I hunt almost exclusively with the 6" 18.75 Khz. coil in all metal with the sensitivity cranked up as high as the machine will allow (usually 27). With this coil and these settings, I have found three silver halves, a silver dollar, and a large aluminum trade token that all read 46/48. But, I have also found a lot of junk in the 46-48 range. Some bent nails and iron seem to "false over" into the higher numbers...

Maybe I am wrong, but my experience has been that the higher frequency coils can cause targets to register at a higher TID, up a notch or so. Even if you hunt in discrimination, it might be worth your time to double check the higher TID numbers in all metal. I have found that the can lids and such can sound pretty good while using discrimination but when you listen to them in all metal they often sound choppy and bounce all around on the visual meter.

In my mind, it is the same dilemma as pull tabs. If you dig a ton of 14-16 signals, your going to get a lot of trash but will also find some sweet gold rings.

Just an opinion...

Downunder I have dug big silver at 46 and also junk at 46
so its dig - or don't dig...this can only be your decision

Some sites I disc out a lot of 9k gold cause I cant stand all the ring pulls....Keeps me semi sane at least ...LOL

Thank you all for taking the time to answer my question. I will continue to dig the number 46 and not resent it so much

Man! Spoopy. You are on fire!
You don't get tallies like that very often, but it's great when it happens.

Good post Mike, I also found that out, as my round 10.5" HF DD registers one notch higher TID number than my stock 9" MF CC. I do not know why, if it is the higher frequency or DD or both?? I would also like to know for sure.

 

[utmike]

That the higher frequency coils have more to do with the targets ID'ing a little higher than the DD vs. concentric configuration. Let me qualify this by saying I am no expert on electronics, I'm just basing my observations on field experiences with the different coils I use. I assume hunting/soil conditions have to play a role as well.

The 18.75 KHz. coil is marketed as hotter on small objects, especially gold. I have found this coil to be very hot on silver coins, especially dimes within 6" or less depth. I have seen dimes ID at 40/42 at these depths, again indicating the HF coil can display a notch or so higher than expected. I've also dug Buffalo's and V nickles that ID'd as high as 18 where the norm is 12/14.

It would be interesting to know if this has been experienced in reverse? In other words, assuming the stock 7.5 KHz frequency represents the "norm" has anyone experienced targets ID'ing in lower than expected areas while using the low frequency 3 KHz coil?

Sorry if this tuns out to be bad info, just trying to respond to your post. Thanks for your comments by the way!
