Thanks for the reply...appreciate it...reppedThere is an option in the controls menu to switch HUD modes. (Combat and scanning) you need to be in scanning mode (blue hud) to use the scanners and mining tools.
With the seismic charges when you target the fissure it will say if its low, medium or high strength. This corresponds to how much 'charge' to put into the charges. Match them up and you can usually get in the blue with just a few decently placed charges.
So when you say in the controls menu, is that left hand or right hand panel - I did look in both last night but couldn't see anything that corresponded?
Sorry for the noob questions, it's been a few months since I played.
EDIT: so on further reading we are talking about in the options menu, binding a key to switch modes. They didn't think to have it somewhere on the UI? Now I have to take a guess at where that mode switch option will be in the control menu...any pointers would save me some time.
Also I've read that this occurs when you have weapons and scanners on the same fire group yet they happily let you configure your fire groups with both without any warning.....humph.
