There are a couple dive shops 6 miles up the road in Big Pine key.
I would try Underseas Inc. I dove with them a long time ago and get my tanks filled there nice people.
Strike Zone Charters also in Big Pine. (I think they bought out one of the other shops called Innerspace.)
Looe Key Reef Resort in Ramrod Key
Into the Blue Spearfishing Charters on Little Torch Key
Most of these shops go to Looe key except for Into the Blue Charters. You could ask? The Adolphous wreck is not far from there.
You have probably gone and are back already. Maybe this will help other people. I spend the Winters in Cudjoe key. Haven’t used any of these charters though except for Underseas and that was many years ago.
