Sorry, this makes no sense...dive logs do not "fill up." You just keep adding pages or logs....By this time my dive-log was filled because of time spent in training even though I just started doing skills. If I had continued with my former dive shop they would need to start a new dive-log because there is no place to record completed skills in contained water. This likely a reasonable cause for my referral.
You say, "referral" but that has a specific meaning in Scuba instruction, which is probably not what you mean.
What do YOU mean by referral?
