Nox 600

[Walking the mile]

Hi, i have recently bought a Nox 600 and as with any detector i have had have laid out different items to learn the numbers and sounds given but for some reason i can`t get the machine to acknowledge a 10p coin any ideas would be well appreciated .

Have you tested the 10p with the horseshoe on? That coin shows to be clad with possibly three metal alloys. It will be interesting what you hear.

Yes it responds with a low noise like iron does

Sounds like it is a 10p, made after 2012, and is nickel-plated steel. The low tones are logical. Pre 2012 10p coins, were a copper base. It'd test a bit higher in tone and numbers. What date is yours?

Just tried a 2011,2014 and a 2021 and none of them responds.I wondering if somewhere on my programme i have a wrong setting.

However there is a great signal on a 1992 so its the fault of the Nickel plated steel used.

Do you remember the VDI reading on the 1992 compared to the newer mints?

The 2014 gives between a -4 to -7 and the 92 is a 14/15.Just tried my vanquish that does exactly the same.

In a cursory search, there seems to be conflicting information about when the composition changed. Wiki shows both 2011 and 2012. And since his 2011 10p coin also rang up as iron, it makes me wonder if it was a mid year change, similar to 1981-82 with the Lincoln cent.

The Royal Mint says January 2012, so maybe the OP is confused about a 2011 being one of his test coins. A 2011 should not ring up as iron, like a 2012 and later coin.

ETA: The OP was not confused. See subsequent posts.

The plot thickens.

The only way you will be able to hear that coin is with the horseshoe mode on. Unfortunately, as you know it will not give an accurate TID number since all the numbers are negative.
However on the Manticore you can slot the iron section where it shows up and identify it. All while ignoring other iron.

Walking the mile,

In addition to the ferrous identification / Horseshoe, were you using Park 1? If so, try Park 2 or 40 KHz. Both of those frequencies should hit the iron core coins much better than Park 1. Park 2 or 40 KHz may even ID them as nonferrous, due to the nonferrous coating.

Great info here! The glad the Manticore can be adjusted to hear it! This is great knowledge!
