10 things a diver should know:

  1. Don’t touch: Even if it feels tempting to touch the turtle’s back or the corals. Don’t. You have no idea how big damage you can cause
    You should read more about becoming a more sustainable diver.
  1. Buoyancy skills: This is one of the most important skills a diver can master. Breathe in to go up, out to go down. Only use the BCD to compensate for depth changes.
    If you want to master your buoyancy all you have to do is practice and practice on very dive. Here are a few buoyancy tips to help you on the way.
  1. Watch your fins: If you don’t have control of your fins, you have no idea what they are breaking or who you are kicking in the face. If you hit something: Stop, look and if necessary take a stroke with the hands.
    It’s all about your finning techniques and knowing where you are in the water. Spend some time training your possession and finning techniques. Preferably on a sandy bottom.

  1. Watch your air: Stating the obvious. Still remember to monitor your air, as often as you can.
    Managing your air is never a waste of time, in the long run you’ll get more dive time.
  1. Never exceed your limits: Even if there the best reason to goo that deep or do that dive. Don’t ever exceed what you feel you can dive, or what you are trained to dive.
    The only thing that can really result form this is DCI. This is the extreme, I know, but is it really worth risking, just to get a bit deeper. And if it’s that cool down there, why not get the proper training for that depth?
  1. Don’t follow peer pressure: This goes with point 5, don’t dive if you are not confident it’s the right dive plan for YOU. Don’t let anyone else say what is right for you. Always hold the right to call a dive.
  1. Keep blowing bubbles: It’s the most important rule in scuba diving, so by now you should already know it. There are plenty of other ways to extend your dive time, so don’t waste time holding your breath. It doesn’t give you more dive time and it can be very dangerous.

  1. Dive gear: take care of your dive gear, and your gear will take care of you. Don’t slack on the dive equipment maintains. If it has been a while since your last equipment checkup, here’s a great guide to getting your dive gear ready for the first dive.
  1. Listen to the briefing: There’s nothing worse than a diver who didn’t pay attention to the dive guides briefing, and ends up getting lost or spoiling the dive, because he didn’t know what to do. So just pay attention.
  1. Don’t touch: Yes we covered this already, but I don’t mind repeating. Don’t touching anything underwater. Take only pictures leave only bubbles.
    It’s really that important that I had to mention it twice. If all divers keep touching just one thing a dive, we’ll end up having nothing left.

    Well, number 1 and 10 are clearly yhe two most important ones :-)

  2. SKuba Steve

    Fun graphic and good list thanks for sharing!

    I’m going to go with Keep Blowing Bubbles (#7) and the most important but a few more…

    Dive with a buddy and keep them close (I know… sometimes people dive solo but the vast majority of divers should be buddy diving).

    Take only pictures and leave only bubbles – oh… I think that’s #1 and #10…

    Keep your skills current. If you haven’t been in the water for a while get in the pool before a trip. Or, better yet, dive at least once a quarter.

      Hi Steve,

      I think the buddy diving is an important factor. Well at least for a large portion of divers, both for the fun of sharing the diving with someone and of cause the safety aspect of it. All in all you are better of diving with a buddy you can rely on.

      Which of cause demands that you and your buddy keep your skills up to date! Very good points! Thanks for sharing.

    Pay attention where you are are in the water. If you are following someone to closely you can get kicked in the face. This also means descending on top of someone or something such as delicate coral or a sting ray and to also include paying attention while ascending so you dont come up under another diver or the boat:)

    • Torben Lonne

      Yes Bobbie, be aware and pay attention. No one likes a diver who is all over and nowhere. Kicking and crowding everyone. Brilliant point! Thanks!

    Love love love this infographic. How awesome it is if dive centers have this on their wall? So helpful and easy.

    • Torben Lonne

      Great, thanks. Let me know if you’d like to use it on your website?

    Check your own and your buddies gear before entering the water.
    Your buddy (paired up with) might think it’s a waste of time! But if your buddy gets in trouble, it’s your buddy.
    No loose gauges/ regs hanging down.

    I like that you should pay close attention to your fins. I have wanted to learn to scuba dive for a long time, but I have been worried I am not quite coordinated enough. If I pay close enough attention to what I’m doing and make sure I am careful, I think I can handle it. I will have to look into getting certified.
