Ground mineralisation

[wal.ellison]

Hi everyone, Just doing a test on the 3030, but somethings stumped me. User manual states if the ground is not heavily mineralised Ground Balance should not be used. On 'hot' ground it should be. Fair enough, but how is anyone supposed to know what the ground on a strange location is like? On my Xterra 705 the ground phase is shown when I Ground Balance, so I can see how hot it is. Is there a function somewhere on the 3030 which will indicate what the ground mineralisation level is? It seems silly to state you need to do something without any indication available to tell you when it needs doing! Be glad of any advice on this. Many thanks,
Wal.

I believe if your auto sensitivity is quite low that means your ground is minerlized. Auto sens of 10 to 15 lets say

In your case, you can rely on the Ground Phase reading of your 705 but you are right, Minelab does not tell you exactly what high mineralization is. I would consider anything less than 10 on the Auto Sensitivity high mineralization and would consider trying the GB feature to see if it helps.

Thanks, guys. I can see the logic of your advice.
