My suspicion was that it was Divefriends. I sent them an email earlier this morning to confirm and I am waiting for a reply. I would like to hear from the two posters that they were referring to Divefriends. I could not find any info on their website regarding such a policy or solo waiver. I personally don't have a big problem with the policy but I am solo certified so it does not affect me. I understand how others would want to know beforehand and have the option to chose a dive op that does not have such a policy. I agree that the policy should be on the ops website.
