Can I go scuba diving without certification ? Seriously think about what you just asked. You want to do your scuba diving without certification. You can dive but can you make sure the safety as you can be the deciding factor in someone’s death or survival.
How long have you been out of the water? Can you hover horizontal and Be completely Neutral in the water while taking your mask off and putting it ack on with out moving more than 3 ft up or down?
Can you respond and have you been practicing to OOA situations? Can you plan a dive and stick to the plan. Depth, time, buddy separation, and other skills you should have demonstrated mastery performance in your Open water class.
If any of these is questions is a No, then you need to get scuba diving certification and be proffecient in your current level before trying to advance to dive. Unless you just want to snorkeling in the shallow waters, for scuba diving.. it’s really high risk to your safety.

Please understand that diving is a perishable skill. Staying current on dive theory and current practices is important as well. It really depends on your honest skill set right now. Take a scuba diving course near your area, you will learn scuba diving basic skills and you should be ready for the course.
Would a lot scuba diver in the deep ever not be a certificated ? No, they are good diver and certificated, they can be the deciding factor in someone’s death or survival.
Sorry to be playing devils advocate here but this is something I have to voice my opinion on a put my foot down on. I’m not being an asshole either. You will literally risk your life and the moment you in the deep, you could have issue and risk your life as you are not certificated.
I’ve been on dives and people joke about how they can’t swim but they can scuba dive because of the BCD. I couldn’t believe my ears the first time I heard that.
Learn how to dive, only then do the course and become a certificated diver so you don’t risk your lives.
