A bit of background was that the call was sent out to the most experienced divers and operators for this call out. The inexperienced diver in question was not on the list but showed up when he heard the radios go off that morning. We would never turn away help, but the decision to deploy him on a dive that he has never done before and in the conditions we were in was wrong. As mentioned above, a diver should work his way up to status and not be thrown in due to the frustration of an officer whom is not patient in sonar surveying.
