XP ORX hot rock indentification

In this short metal detecting tutorial I want to talk about better identifying those pesky hot rocks when hunting for small Gold.
I use the word better identifying because totally rejecting them can be very difficult if you are searching on HOT ground.

This is simply a matter of ground balance, hot rocks can be totally rejected using a ground balance of 87 and above, so when out metal detecting using the XP DEUS or XP ORX factory discrimination modes you will never know when you are passing over a hot rock.


Watch the mineralization bar, it will always read high over hot rock.

(Always ensure the ground numbers correspond when hunting for Gold on hot ground.)

However, when searching in highly mineralized ground this type of rejection is not as simple as it may sound.

If your ground is HOT, you will need to ground balance in order to obtain a smooth operation, and in most cases the set ground level may fall below the hot rock range.

The easiest way is to change the reactivity settings to allow a smooth operation on your ground once a correct balance has been obtained, the audio sound from hot rock changes depending on what reactivity level you choose.

With a little practice using the Gold modes on your XP, you will soon learn that the solid repeatable sound from a small Gold nugget is very different to the audio warble of hot rock.

Also be prepared to lower your sensitivity a little if required.
