The XP ORX hits 3 Silver coins

Just out of curiosity I wanted to give the ORX a try with the X35 search coil, to date all of my searches have been with the High frequency round coil, supplied with the machine.
I wanted to know if there would be any noticeable characteristic changes between the coil types.

My XP ORX metal detector in the field

So far the HF coil on the #XPORX has been faultless with a finds rate on par when comparing it against my Deus, finds have been varied and at various depths, I’m very pleased to report Silver coins have started to make a regular appearances with the ORX using the HF coil especially when using 27Khz.

ORX finds Medieval Silver coin

I have been using the Factory Deus fast program and comparing the ORX using the Coin Fast program, so far they appear to be equal although the ORX audio sound is a little different.

X35 coil ORX

My 11” x35 Coil is a real workhorse, it really earns it’s keep and is a great stubble basher. Using the ORX arm strap is a must when searching stubble, keep it loose so your arm can easily slip in and out, but it is a real asset.
The coil paired to the ORX within seconds, just like the MI-6 and the WS Audio headphones, I must say the pairing is child’s play, smooth and faultless with all of the above items.
I like to use the headphone adapter plate commonly known as the horseshoe adapter with my XP machines, this allows me to use the lightweight FX02 headphones, they are cheap but produce a very nice sound and have an in-line volume control.

Originally I wanted to test the X35 coil using the lover frequencies, 4 – 8Khz, however my second signal was a hammered James 1st Half Groat (1605) so I kind of figured it would be mad to ignore an opportunity of finding more low conductivity targets in the area.
I decided to stick with 17Khz and it paid off because 30 minutes later another Silver coin appeared, this time an 1836 William IV, 4 pence.
The X35 coil was behaving so well, I decided to push a few boundaries and try and find what the ORX limits were, and this is when I really began to see what it had under the hood.

ORX high sensitivity

My first adjustment was the sensitivity, with the factory pre-set of 90 the ORX was very stable, I started to bump it up a little, and was amazed to discover it was still stable on the stubble at 96.

ORX lower discrimination

My second adjustment was the discrimination, I lowered it down from 7 to 6, this started to make the machine a little “Edgy”, just how I like it, but it was still very usable, even dropping down to 5.5 the iron identification was still doing it’s job.
Even at the factory pre-set of 7 large round Iron gave a good sound, but this is normal with all machines, so I thought, what the heck lets see how it goes at 5.5.
I must point out that at no point did I feel the need to ground balance the machine, the ground reading read – – most of the time, indicating there was not enough mineralisation to warrant any adjustments.
*Note – When you see – – appear the machine will default to a pre-set ground balance, which is perfect for most inland searching. I am hoping to send in a more detailed article on the ORX ground balance soon.

XP ORX finds 3 Silver coins in 2 hours

This paid off because I got a very quiet repeatable signal and up pops the find of the day, a part of a Silver Celtic coin believed to be (Verica AD10 – 40).
It’s not only me but several other ORX users I have reported that the ORX has a strong liking for Silver, next time I will be giving it a good run on the lower frequencies.

Happy hunting !
