Its been a while since I dived my Suunto, but the deep stop occurred at 30m on my D9, using RGBM. At 15m you're well inside the normal decompression zone and you're offgassing, so its highly likely your deco penalty simply cleared due to ascending. The stop time is based on ascending at 9m/min...

I was not critical of individuals or agencies, but I do believe the practice is undermines training outcomes. That comes back in the cost of insurance premiums on the operators. I don't advocate for this. If the group size or skill level warrants an instructor and DM, only a fool doesn't...

End the customer relationship, stop referring to divers as guests and students, the instructor and the DMs and boat crew are not hosts. Too many instructors lead the dive and have a DM follow as the sweep. Not enough instructors mentor diving, rather just teach the certification being paid for...

The thing to be wary of is punching along behind the DPV for 10mins, slowly getting deeper. If you're having a good time you're not adding air to the wing. When you reach the wreck and slow down, suddenly you're hard on the inflation button to stay off the sand. The two brands I have used don't...

I love the Perdix AI, its just that little bit more flexible in its screen settings. If you have zero interest in reorganising or changing the data on the screen, or having a compass, the Peregrine is a nice computer. But you won't be disappointed with the Perdix, and you can have it now rather...

Mine are straight into the bottom HP port. I have an SPG in my bag for a save a dive kit but that is it. Had both fitted for maybe 200 dives, never looked at the SPG.

Welcome Alfredus I have a bit of family in the city of churches, spent many a holiday there, never felt like I was missing out.

I prefer the hoses close to my neck, rather than looping out. Milflex is good but an elbow is still more comfortable. I tried a 90⁰ but a 110⁰ feels better. It's a trade-off though, the elbow makes it more awkward to clip off to the shoulder d-ring. I'm still not sold on a configuration yet...

I tore an Sci-tech wrist seal on mine, all I could get were Fourth Element seals. They look and feel identical. I have seen a Waterproof HD neck seal and it looks different in the stock photo, but I'm not sure I need anything HD when the neck seal seems to be holding up okay. Perhaps that is...

I don't overtly disagree, but I'd suggest there's residual risk rather than its very dangerous. Most computers are more conservative than recreational tables and much more than the US Navy tables. If the computer fails and you're inside NDL, ascend and you're good. Conduct a precautionary safety...

Angelo's posts may give you that impression, but its not the case. Millions of dives are conducted every year, the decompression diving community is very small percentage of that. Few dive plans consider deco, most dive plans explicitly detail divers are to avoid deco. Many divers don't plan at...

The hope is not blind, hence when the computer is truly, absolutely essential, people have redundancy. People ensure the battery is charged, the firmware is updated, tissue logs are not inadvertently cleared. In the map example, coverage failure doesn't leave you lost, it leaves you exactly...

Sharp scissors. I trim one ring at a time on the neck seal until it doesn't feel suffocating. Wrist seals are easier, push your had through and see how much length is tight to your arm and if its bunching at your wrist. Shorten if necessary, leave it alone if its not a problem.

When I dived at Truk, there was normally a bottle at 6m or so. The guides said nothing if you sucked on it, but your dive sites started to shallow out again. If someone in the group couldn't manage their gas the best course of action was to reduce the risk exposure. Drop bottles are inherently...

Might feel like it, but no chance. 10s per sleeve maybe, unless you have the skinniest wrist ever. Regardless, whatever makes you happy. Exposure protection can be one suit fits all, if you aren't sensitive to changes in the environment. What works at your current age won't work for you forever...

The scenarios are quite different. OxTox doesn't kill you, anywhere. In the chamber the dive you carefully and bring you up if required. Spasm in the water and you'll drown. The margins are different because the consequences are different.

Supporting local is great, just remember its a two way street. When the LDS takes an exclusive deal with a supplier, its guaranteed they're supporting you. Could you have this exact conversation at your LDS? Or would they just walk over to the stand and sell you an Aqualung? Will it be the more...

Its not an absolute question, there is no absolute answer. Water temperature is a key ingredient, and your tolerance to cold. A thick wetsuit takes an eternity to get on and greatly restrict movement, but there are some exotic ones that have less impact. I'd wear my drysuit over a 7mm any day of...

You've learned the concepts, its not certain you have learned the theory. None of it is rocket-science, things like Equivalent Air Depth aren't even overly useful. But it all has a purpose and someday, you'll need EAD just like MOD. I'm curious as to why you were watching MOD on your deep...

Welcome Androl. I have never dived Port Phillip Bay, but did some diving last year with a guy that spent many years there and he waxed lyrical about it. Sounds like its a tricky place to dive, so give yourself plenty of dives before you start to measure yourself against the stories of tropical...
