Im going on a vacation, never been scuba diving before. Where is there a place to rent scuba gear for a reasonable price? I dont want a pool or set up atmosphere- I’m looking for reef and actual marine wildlife. I’m assuming these are guided experiences. About 100 mile radius from Orlando. Thank you for any help.

There are companies that will take you on guided scuba tours, but you will have to attend an "abbreviated" scuba course first.
Scuba diving can be a dangerous sport without proper training, so you can’t just rent the gear and have at it, without any training at all. You can’t even rent the gear yourself, without a certification card.
