My son has a decent drone with camera. The issue is weight. He has a GoPro on the drone, but without a high powered light the camera is ineffective in the dark. The weight of the light he needs in a cave is just too much for his drone. The other issue is if there is any error in flying the unit is probably ruined or lost in that upper passage. At least outside it can be controlled crashed, but in a cave with boulders and such that would not be the case. Outside his drone uses GPS to come back to his controller when there is a problem or when the battery runs low. In a cave there is no access to GPS:-) But, having said all this, I do agree, this can and will be a great tool with the right setup.
