Hi Everyone, A post has been doing the rounds from an exploration manager looking for a fieldy and geologist and was having trouble finding anyone. Considering the current environment this is likely to be an ongoing issue. I would love for a technical solution to this problem so lets run though a small set of considerations around commercial of the shelf sensing on a exploration drill rig. Imagery Ensure that the light output is stable in both intensity and colour balance, LEDs are a good choice here for practical reasons if you are willing to suffer higher maintenance costs and calibration issues quartz halogen bulbs are preferred.
