If you’re military, check out the local bases to get better deals on rentals. I don’t know about NAS Pensacola but Hurlburt Field has a good dive shop with lots of gear. Check with Outdoor Rec to see if the Airmen’s program is offering any free dives.
Whether you are military or civilian, check the Under Pressure Facebook page. If anyone is diving this time of year, it will be posted there and you’ll meet some good people.
