Sad i only have the RK3s

Congratulations!

Bold move! Congratulations and good luck. Amazing channel, great videos, strong values.

Love the “red flag to a bull” statement, bulls can’t see red either, they are attracted to the movement 😉.

Absolutely ridiculous. So if he didn't have the means to pay, he would have just DIED. DEAD. No coming back from that. A CORPSE! All because a card got declined. Absolutely unacceptable.

#askmark I am a tall skinny guy and very LEG heavy. I don't need much weight to sink but if it is round my waist, my trim is terrible. I usually add some weight to my tank band but need to add enough to compensate for my Dump-able weight around my waist. Is it worth just having a small amount of non Dump-able weight, or should I still have some that I can get rid of if needed. Thanks

Hello iam using a Mares Dragon BCD and i want to switch to Mares XR rec Tek , iam heavy and I fear that 17L is not enough. Can you advice le ?

And the times of this ignorance God winked at; but now commandeth all men every where to repent: (Acts 17:30) The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance. (2 Peter 3:9) And as it is appointed unto men once to die, but after this the judgment: (Hebrews 9:27)

i owned mtx-rc for twinset and mk19/g260 for sidemount, mtx-rc is a bit heavier and bigger, but the looks are really cool

What size O ring are you using to clip off the mask?

My actual instructor doesn't know how to make a fun dive. Check the valve, clip this, no camera, no fishes, all exercises, even for a simple refresh dive. I have had it

It is as if you were talking to me. lol. Thanks for the great tips.

#askmark - 4 dives on my Perdix 2 and loving the AI and the easy to read screen and functionality. Here's another question on SAC rate. Perdix is telling me my average SAC is 20.4 psi/min. My introductory understanding is if I want to convert to cubic feet/min (RMV - using DAN's definition) I would need to factor in tank volume and working pressure. Does Perdix allow for this? I have two tanks I routinely use that are slightly different. I don't see where I can enter "Tank 1- 100 cu ft, 3445 psi" and Tank 2- 100 cu ft, 3144 psi" in the computer. Shearwater associates the AI serial number to the tank to support up to 4 transmitters. How about managing multiple tanks with one transmitter.

Sounds like a great watch! Seems to have a lot of features, however it would be nice if you could locate the dive boat underwater.

Tusa Paragon is still the best mask for me

Having seen how superficial regulators are often cleaned by diving centers I quickly wanted my own, so I would move it even before the dive computer. Tecline has really nice sets for about 450€

I just tried a wing style BCD the first time and I m sold and got my own one. I always felt squeezed when inflating an normal BCD. I still prefer the jacket style ones with integrated weights as it's more comfy for me than having the weights on a belt

#askmark would it be possible to explain how the SAC rate is calculated in the shearwater? It seems different that the SAC rate calculation that you can find in internet. I also know that everybody is different and the condition also affect this consumption , but what value would be a average SAC rate vs a good SAC rate?

Used MK1 Descents are like $250 now. Pretty good deal.

When our son started diving with me 4 years ago at age 15, my wife (she doesn't dive) insisted that I maximize the safety factors. One of my solutions was to get myself a Shearwater Perdix AI with two transmitters. I mounted one of the transmitters on my 1st stage, I mounted the other on my son's 1st stage (both on a 6" HP hose). I also got him a hose-mounted AI dive computer (Aqualung 550 series) so he can keep track of his own dive data. With this setup, we're both diving on computers (safer than tables, IMO, and both are NITROX-capable) and as long as I'm diving next to him (he's my buddy so I'd better be pretty close, right?) I can see what his air pressure is without distracting him - usually this is a drive-by as I swim past him. The Perdix reconnects to his transmitter pretty quickly if I've gone out of range. I also have a separate analog SPG on my rig. I love the Perdix AI it's bombproof and way more capable than I'll probably ever need.

The sticker on my Apeks transmitter has come off and now I can’t connect it to my DSX as for some reason Apeks are one of the only MH8A transmitters that don’t etch the serial number on…completely stupid. Does anyone know if I’ve overlooked something here, otherwise I have a perfectly functional transmitter sat on a shelf

Just maybe when I was in the market for a now computer, I would consider shearwater. But at the time I needed one shearwater didn’t have any under €1000. I got the Suunto Eon Core and frankly…. After testing and comparing the xt,….. I can’t find a single thing that I miss and even have e few hundreds euros to spend on something else. 😉

I've been of the opinion (and like assholes we all have one that might be different to someone elses) AI is an awesome piece of technology looking for a problem to solve. Hear me out! Yes you get the benefit of knowing your tank pressure on your dive computer. Yes you get to see what your SAC rate is right now (but ask yourself what you can do with that information right now?). It can give you a proxy for how long your air *might* last at that depth too. All great stuff, but not exactly game changing. How much harder to do this (angles wrist towards face) versus this (grabs analogue gauge in front of me)? Its easier for sure - but is it $600 easier? When you consider the premium payed for the AI dive computer and the pod - you could have had another dive trip! Now I know I'm likely to get ripped a new opinion by the AI fan bois, but just stop for a moment and ask was it really that big a difference to your diving and at $600 do you still feel you've got value for money from ALL the extra information you have? Of course if money is no object - then sign me up for two.... On that - Saw a diver on the dive boat today with a $400 reg and $700 worth of pods plugged into the HP ports. She wanted a backup to her BT AI, so bought another BT AI dive computer as its more of a weight saving than having a HP hose and gauge!

#askmark please do share some tips for storage and maintenance of the transmitter. I just purchased the Perdix 2 and Swift and has a chance to break it in last month. Given the investment in it any tips would be super helpful!

As far as I'm concerned, there is nothing else one should consider other than Shearwater.

This is a perfect video for as I'm in the market for a dive comp with AI. I'm a new OW diver. Would you be able to go into a little more detail on how to change the battery of the transmitter? Thank you in advance!!

Mark, do you know of any studies on the effects of Bluetooth transmitters on underwater flora & fauna? I'm curious to know if any sea life are sensitive to BT and how it may affect them.

#ask Mark, this may be a stupid question but I was curious as to how the pressures from a 3,000 psi tank to a 30 PSI is actually stepped down is it a metered orifice or a diaphragm with a spring load?

Great insight, thanks Mark

Great review Mark!

Conclusion, besides paying DAN, get a Medevac worldwide insurance aside.

Check out a brand called "tough tags", it's custom printed labels that really do the job well. I use them on loads of gear, notably thermos cups that go through the dishwasher cycle and come out unscathed. Great for climbing equipment too.

#askmark Hey mark, quick question about carying cylinders. Does it really matter if you carry the cylinder by its valve? During my open water i was told its a bad idea. I work in a dive shop though and everyone carries the cylinders by the valves. So does carying a cylinder by its valve comprise the threading?

Mark never had a teddy bear...he had and still has his fluffy shark ;) 😅

So you'd be better off avoiding the buckles of the deluxe as this is just as easy to get on and off in the water (thinking my 200 odd rib dives last year) as the deluxe? Great video as ever!

Hardly covered any of its top functions around CC... CC to OC bailout and back...

Sea snake patterns do repel them, has been tested

Guys, I mean most scuba tanks are in bright colour anyway, so….

#Askmark I am turning 17 this year, should I look into a drysuit and a drysuit course to take or should I wait until I stop growing. It’s just we live in Massachusetts and it’s cold. I have tried a semi dry but am still curious what you think. I’m an advanced open water diver and am looking for the next step

#Askmark will you be doing a review on the new Suunto Ocean Watch? Also as someone doing their open water soon would you suggest getting familiar with your own dive watch, whilst doing the open water, rather than looking at other bits of equipment like a BC or regulator. I’ve heard dive computers with dive schools tend to be notoriously unreliable with breakages? (I already have fins, mask and a wetsuit as I snorkel as well)

When will you review the new suunto ocean?

Where might one obtain that loop that you run through the eyelet in your dust cap? Cheers!

In terms of things I would be worrying about, sharks eating my fins are not really on the list. Loosing your dive buddy or underwater mix ups because everyone looks the same is probably a more likely scenario. Following that surface visibility. Having a bit of colour or some way of easily being recognised is probably more important for most divers.

The term ‘Yum Yum Yellow’ came about after a series of tests in 1971 by Dr Scott Johnson and Ernest McFadden on the reflectivity of sea survival equipment. Out of the black, red and yellow devices used in the study, it was the yellow life vest that was repeatedly attacked.

#Askmark Thanks Mark for the grate content and advice. I have been told that using my regulators and BCD in the pool could damge them is there any truth to this or are there spcial precautions that I shod take to protect them when in the pool ?

These are actually really solid tips. I've been diving a long time, and I've been guilty of couple of these, and I've seen all of them.

aaah shit ... my wetsuit are yellow

Bulls don’t see red as well. They are attracted to movement

I just bought mine wioth a swift transmitter a couple of weeks ago after watching your review... great computer.. love it.. thanks for all the good work... and an extra perk is that they are Canadian as well.. so technically I am supporting local

One pair of my fins is yellow, one is blue, another is black. I’ve never seen a difference. The sharks I’ve encountered are either curious or shy and it doesn’t seem to matter which fins (or colour tank) I’m using.
