A couple of years ago I was on my AOWD course in Dahab, Egypt and was surfacing from the navigation dive. It was Ramadan so the dive site was deserted and I didnt see anyone near the shoreline and was feeling quite relaxed. When I broke the surface i remebered to extend my arms with the inflator hose in my hand and boy am I glad I did. Just after my eyes got above the waterline a kite surfer came into view about 2 seconds out from my head with more than a bit of speed on him. He managed to avoid my noggen but just barely and boy was I glad I would have at least had my hands inbetween me and the tip of his board. Since then I never forget to keep my hands up when surfacing.

in my experience dive masters and boat crew are inclined to hurry their group into the water, and that's when slip ups occur. Ok they do it because some people tend to be disorganised and hesitant, but the risks of sending an unprepared diver over the side surely outweigh any extra time taken. Number one requirement for dive group leaders is Patience (that and situational awareness), in my humble opinion. Great video thanks James - pearls of wisdom!

Hold fast and do your procedures. I've found that doing the exact same pre-dive gear up sequence means I am less likely to forget anything. It may take me an hour to go from arrival to in the water with tanks on, but I have everything on and I know that it works.

I sometimes had the same feeling on some dive boats. But if you say "we didn't complete our buddy check yet" they will probably go to the next one and help them to go into the water so you have some extra time. :)

By and large my experience is that dive operations do focus on safety. They must handle the fact there are those ‘That’ Divers” on board. (See Divers Ready Don’t be ‘That’ Diver video.). Also, they are running a business that balances their reputation, safety, diver experience with operational costs without sacrificing safety. Once I did dive with an operation that began to (can you believe it) rush surface intervals (20-30 minutes short)! This was under pressure from the resort they were owned by, to get the group back for lunch so they could serve the group and close the kitchen! Wow! We let the captain know this was a significant safety issue and our group was not getting back in the water until our surface interval obligation was complete. That settled the matter and was the last time I would visit that operation!

As a retired Airline Captain, a licensed boat Captain, and a Master Diver, I'd agree that situational and personal awareness is always great advice and the mark of a responsible diver. Being on the surface in areas like congested Caribbean waters or anywhere for that matter scares the shit out of me too for all the reasons you elucidated! Well done! Thank you for helping to educate divers so competently.

I did some power line work on the port of Miami earlier this year for a couple months, the boaters there scare the hell outta me. I'm looking at all the 50ft+ boats and it looks like it's being driven basically by a bunch of children that have no clue how to operate that vessel, loud engines, loud music, and girls screaming. And you know it's some trust fund baby that won't get in trouble at all if he hits someone.

Thank you! I especially appreciated the suggestion of blowing up both safety sausages. Usually when my boyfriend and I Dive we only use one. I never thought of the extra visibility. I had a dangerous situation on the surface due to forgetting to check if my BCD would hold air during my set up. My boyfriend cleaned our gear and loosened the valve on the back of my BCD where the inflator hose goes in. After our drift dive was over we were waiting at the surface for pick up. I kept trying to put air in my BCD and was having a very hard time staying positively buoyant. I did not understand what the problem was and assumed that it was in my head. Swells were a little bit big that day and it could have been a bad situation. Honestly, I don’t know why I did not think about dropping my weights. Fortunately nothing happened except for a learning experience! We were with a dive operation that we use frequently and trust and never leaves us in the water long. I did communicate the problem with my boyfriend/buddy obviously and he extra inflated and we stayed up together. Now I only clean my own gear, or we clean it together, and I always check my BCD before getting in the water and I remembered the importance of having the option of dropping weights. I did sit out the second dive just because of the issue, stress and the confusion of what could possibly be wrong with my BCD. We did not discover the loose valve until we got home.

Definitely excellent advice! I had to yank my buddy out from under a ladder once. He did not stay clear of it, and the boat drifted him under and behind it. Another dive buddy didn’t,t lock his arms upon stepping on the ladder, and as the boat’s stern jigged up, he caught it in the ribs, and cracked two of them. I once surfaced and reached for the tag line, only to hive the diver ahead of me not notice it wrapped around her leg. As she pulled herself toward the boat, she took the line with her, forcing me to fin like hell to get back to the boat! Another buddy took his reg out returning to the boat, kept getting hit by waves. I had to yell at him to put his reg back in his mouth. Snorkels also don’t work in wavy seas. Water washes over them. Just a few true experiences of mine 😩

Just last month I was with a group at the surface and a (drunk? or just ignorant?) boat raced directly at us to “check out what was happening” with no awareness that he was literally about to run us over. He veered at the last minute but it was a very close call. I doubt he heard our colorful language over the roar of his engines…

As a Divemaster with a FL Keys dive operation, I really value these videos you produce. They are an excellent review/reminder. For all the other dive professionals out there, even as you monitor the clients doing their buddy checks, don’t forget to do your own. Although rare because we get so many repetitions, occasionally a DM will check everyone else’s air being fully on, then not check his/her own… speaking for a friend… 🙄. Keep up the great content James (and come on down to Islamorada for a change of pace!).

Having responsibility for someone else very readily diverts your attention, I have noticed this myself that while looking out for my dive buddy (wife) I sometimes will forget something on myself, and I have to ask for a buddy check after I checked her over. It's also evident with non diving scenarios like trying to get the kids ready for a road trip I'll leave myself until last to worry about and always forget something.

James. Great stuff. I would add that part of being a good diver and continuing our education as divers is to observe and discuss gear set up while setting up gear before leaving the dock and while traveling to the dive site or between or after the dives ( conditions permitting). We all have different experiences and teachers but should be open to learning new things. I am always interested to see how someone else configures their gear. I would also encourage more experienced divers to be receptive to questions about gear, boat procedures, dive conditions, etc…. My $0.02 worth.

Great video thanks James! Good idea with the second DSMB. I've seen language is a factor. Diving in Sharm (Red Sea), we had a Russian guy who only spoke Russian (noone else on the boat could speak it) . He could not understand the dive brief and was buddy with the dive guide. His idea of a buddy check was "everything OK? Let's go". The Russian was clearly very inexperienced. He kitted up and jumped with a used cylinder! He was saved by a free flow (he jumped in holding his reg in his hand?!), he didn't know how to stop the free flow and the dive guide had to swim over to him. He checked his SPG to see how much gas he'd lost and saw it clearly in the red on 40 bar! We ended up hanging around on the surface while the crew/guide changed his cylinder. I've never felt more vulnerable in my life.

Just this past Friday, I was diving off Pompano Beach FL on a boat dive. Seas were a little heavier than forecast, by the end of the second dive we were getting 5+ foot waves. My buddy and I were waiting for the boat to pick up another group, when a center console fishing boat decided to come blasting down between the second and third reefs, apparently too fast to see the dive flag, DSMB or a dive boat less than 100 yard away, picking up divers. He never slowed down even after the dive boat captain blasted the horn 3 times to warn the idiot. Luckily we were paying attention and were readying to dive back down if he came any closer. This seems like another reason to make sure you surface with a good air reserve.

Even from a recreational standpoint single tank diving being able to reach your tank valve is something that I think is important. In the event you screw up your air check before entering the water you can turn it on yourself. You could also prevent buoyancy issues if your first stage fails, air share, and thumb the dive. Florida boaters or your local lakes… I keep off the water on holidays. It’s not worth the risk for me. Don’t forget, when your on the surface to wave your sausage around. 🤘🏻

When I started diving, I figured out pretty quickly that there are two places a diver should be. On the boat, or submerged! The surface can be brutal. I had a dive buddy who liked to get in the water, then take a minute or two to "get comfortable". I always told him, drop 40 feet or so, THEN get comfortable! I ended up towing him in twice because he never was able to get comfortable. Stopped diving with him...

Thanks for the reminders, even for an experienced diver, these tips are often neglected. On the eve of a 27 dive week in Cozumel, it’s always good to go back and practice the basics. BTW, same experience on the Speigel Grove, except the current was ripping and several people did not slip in on line, instead giant stride and promptly whisked away. The Captain called the Coast Guard to pick them up. The cattle boat we were on would not have made the rescue. Also, roughly 70% of the 40 divers ignored the briefing.

@diveguernsey6521 2 жыл бұрын

Not many in the industry I agree with, but we could talk shit for hours! It's nice that divers trust my skills as a skipper, but i'd rather they looked at the boat when i came in to pick them up. Mask and reg on / in until on the boat is a big peeve of mine. I call it "gear rejection" and it scares the hell out of me. Always say to my students that the most uncomfortable place to be in SCUBA is on the surface. I don't like buddy checks in the normal way though, as they allow complacency within known buddies as there will often be a dominant one and a submissive one - as in the story. I believe that every diver is wholly responsible for themselves and the a good buddy / crew will help as a secondary. We do a lot of solo diving too, so it gets people ready for that. Cheers!

i don't think a lot of people are taught of what to look for when a tank is turned on and then off. while the boat is docked you are asked to set up your gear. however because sometimes there's leaks the crew turn off the tanks or you might have and then forgot for the boat trip so just because you set it up when you got on the boat don't assume its still on. after sniffing the air for quality take 3 breaths, if the needle on your pressure gage moves, your tanks off, just taking one breath doesn't help. test it out next time to see what it looks like. just curious does air integrated show the same reaction on pressure drop. if you're running out of air on the surface you can manually inflate your bcd without using gas.

If I understand your question right, I think you have forgotten that the valve is on the cylinder so if it is turned off no air gets into the first stage at all. When that cylinder valve is opened it allows air to enter the first stage where there is a narrow bypass route direct to the high pressure port so you get a tank pressure reading whereas most of the air passes through the first stage mechanism, pressure reduction takes place and out to your second stage. I have seen people open their cylinder valve sufficient enough to give a pressure reading, it only takes a quarter turn of the valve, but not enough to allow the flow required or breathing, or take a pressure reading and shut the valve again. Initially that high pressure/medium pressure air now trapped in your first stage will allow you to take a couple of breaths, but if you're watching your pressure gauge while you do so, the pressure reading will drop like a stone. And so to the 3 good breaths of a pre dive buddy check that will alert you to that problem as you will struggle to breath by the 2nd or 3rd inhalation.

Agree about positive buoyancy at the surface, except, if you have a fair distance swim back to the boat, and you have plenty of gas, if it is much easier to swim without a fully inflated BC.

@toriless 2 жыл бұрын

It does not require full inflation to be positive buoyant. I took swimming lessons to explore stroke that would work better with a BCD vs normal swimming. Probably a dumb idea but strokes thar vary depth like the butterfly fail compared o the lazy backstroke. It is so chill but it requires a horizontal position. Tilting the head towards the shoreline is key.

The surface is exceptionally dangerous for divers. One of my high school teachers was killed in Key Largo after he was run over by a boat while he was at the surface. Just last week, a recreational boater got uncomfortably close to our dive boat. He had no reason to get so close to our boat. Luckily, we were all on the boat. But he ran over our mooring line at almost idle speed. This is where the dumbness gets worse...with our mooring line slightly wrapped around his prop, he brings the lower unit out of the water. With engine still running, his wife reaches towards the prop to get the line out of the prop. It wasn't until a bunch of us yelled from the dive boat to shut his engine off that he thought to even shut it off.

Yeah, lots of danger out there. Stay safe!

on surface with a group and everyone on the tag line make sure everyone is ok. there maybe someone who has issues who needs to go first great video. do you mean you don't get a refund for the gas left in your tank. ie keep your reg in

All the time you get, "It's got 90 bar left in it" as if it's less charge being 1/3 left as if it will be cheaper - never happens in reverse though!

on a identyfication dive (to see if the sonar contact was a life mine or not) in the mouth of a big river there was only a one hour dive window between the tides ,i gues there was made a mistake wen checking the tides tables ,wile the 2 divers were coming up the curent cicked in with a bang and one diver was ripped of the safety line and was out of siting in no time luckely we had radio contact with the ship so they could guide our pursuit of the diver as the had hin visibol from on top of the bridge ,we had to push the zodiac full trottle to catch up with him but we did ,i can assure ya he was not happy and wen back on board he let the officer in charge now it loud and clear (he also got us drunk later that evening in the dive store to show his aprecciation for our allertnes hehehe),but it just shows ,accidents can and do happen wen details are not checked and checked again just to make sure he ,greets Dirk (retayerd Belgian navy) dirk

I saw people who won't wait for their turn to get back in the boat and just passing people on the tag line is that okay or shall we wait go up in turn coz he was 4th or 5th and he just jump ahead of us to get on board through the second ladder that they haven't prepared yet and throw a tag line that was only managed by them and wasn't tied to anything

Pretty good video as usual James, thank you for that. Question: what's the difference between a fins-on and fins-off ladder? It is up to the operator to decide how to use the ladder or there is a structural difference? Greetings.

@DiversReady 2 жыл бұрын

There’s a structural difference. Fins off ladders have closed in rungs, whereas fins on ladders have open ended rungs

Had a dive boat crash down from a huge wave on my head just after backroll into the water. Nearly severed both vertebral arteries. Could have died. Will never back roll again.

How do you know if it is a fins off or fins off ladder? I only do shores dives but may do a boat excursion when on vacation since most commercial dives are.

@AndrewS-ht3uo 2 жыл бұрын

You should always enter with your fins on off a boat. At the end of the dive you usually grab the ladder then take your fins off and pass them to the first mate or DM helping you out. I’d suggest doing a boat diving course prior to going out on a boat if you’ve never done it before.

@RichWilx 2 жыл бұрын

Fins-on ladders have a central spine with the rungs protruding outwards. They are designed to allow the diver to easily climb the ladder without removing fins by sliding their feet in towards the spine. The diver should hold onto the rungs and NOT the spine as they climb the ladder. Fins-off ladders are designed like regular ladders. The diver needs to remove their fins first as trying to insert a finned foot onto the rung is extremely difficult.

We’ve been in our 5 metre boat and nearly run down by other inattentive boaters. I’d they don’t see a boat how would they see a head. Scares the sh*t out of me too.
