i dive twinset now!

where do you get that lead bar from

Good video but the background "music" is driving me mad!

Were do you get a trap and valve kit for hp100 tanks and hp 80 tanks

Can we still but the simply scuba mk1 light?

Supercool short where did you bought It?

Great insight and tips thank you!. What is the make/model of the 90 degree elbow on your primary 2nd stage? cheers

I love all your videos. Especially the tips and tricks. Makes me a better diver every time I watch it.. Thank you, Marc!

Tried it. Didn't like it. This was never intended to be used in open water. The original lesson plan called for tank valves to be hung on bungees. This didn't work for deep water entries and after several fatalities, a hard point mount was added. Plus no redundancy, what you wind up with are independent singles which is pretty dicey in a cave. I will say sidemount is excellent for mounting stages. If you use a bungee and ring system, the stages ride right beside your body and can be pulled down to deploy or to check the valves.

I would say a properly fitted harness will ease somewhat the burden of moving a twinset around. Proper fitting doesn't make them light, but it is surprising how much more comfortable they seem.

Background music during the first episode of season 47 was way to LOUD very hard to hear and understand what the players were saying. Please tone it DOWN

I was gonna get me an Apeks Tech Short, but it looks live i need more boltsnaps first.

I’ve just got an Xdeep Zen and I can’t get the set up right. With the length that I need in thr shoulders for my shoulders to fit properly the backplate sits low and my back and the inflator hose is waaay too short.

Thanks for the video. Surprisingly enough it was easier for me to do with my fingers. I found the tool made it more difficult.

I’ve never used a beard balm. Is there a brand that stands out and you recommend?

Back in the early 1980's thigh pockets were very popular. The Dive Shop I worked at we sold a lot custom wet suits and they almost always had at least 1 thigh pocket. There wasn't as large a variety of wet suit sizes back then. Many people would buy the pockets and glue on themselves. I really like the Apek and Mares shorts. But, they are way overpriced. Dive Gear Express sales a pair that is less expensive. But now that shorts with pockets are popular. They are more expensive than they use to be as well.

Hi Mark! Where would you put weights, if you need to bring some? #askmark

Would you recommend Aqualung with its restructuring?

good info, cheers from Cozumel, Mexico

What layer do you prefere for 24 to 18 degrees water i go to malta in oktober

Where do you get the elastic webbing bands you're using to secure a back up light?

Very insightful, thank you !

A guide to changing the seals would be appreciated

Twin 12s are bloody heavy - I just got mine back from servicing and after carrying them, I picked up my 15L cylinder and almost threw it up in the air! Great for deep dives, but I think the 'benefit' of not 'faffing' between dives is vastly outweighed by the con of all that weight. Underwater, of course, you barely notice them!

Hi there. Bought myself a mares xr back plate wing system bcd. Never used one before. Will it be tricky to use the first time ? Going to dive at florida Keys in July. Would you recommend using a wetsuit or just a rashguard. By the way, Thank you for all the helpful videos. Always watching from my side. Thank you kindly

Meh. Too much variability in setup for me.

Not sure if this has already been covered but would anybody know and have reference to what submarines use a Mk25 for internal pressure regulation?

My cylinder sometimes gets slanted like yours in this clip. Any tip on fixing it?

Dst and xtx50 best dive invention ever.

You only need to identify as correctly weighted 😂

Best twin set setup and pro ia dive side set hahahah

You're using your cutting tool as a retainer, smart. Didn't think of that.

Top Video & explanations . Thanks

👍

XDeep SM bcd setup

Very helpful, thanks

What is that d ring you use on the bottom left side of your plate for adjusting the harness when you don it?

Hey!!! Im looking to buy my first backplate system. Do you know if the Scubapro Stek pro backplate is compatible with the Apeks wtx30??? Thank you Mark!!!

I dive twins for the reserve gas and redundancy. Better to carry gas you don't need than to need gas you don't carry.

I’m so glad I skipped diving twins and went right to breathers that shit looks so damn heavy my breather only weighs 70lbs with 20lbs lead mount to it for my dry suit lol in wetsuit I only need 10lbs lead

How do you calculate the amount of lift you need?

Thank you Mark, even after three years you're still helping a lot of people!

interesting topic, i'm 177cm 80kg have been diving with 2 piece 7mm suit hood, gloves and boots, so lots of float! 80 al tank and carrying 2x 11lbs in bcd pockets 2x 2lbs in trim pocket and 4 x3lbs on the belt, 38 lbs all up and i know if i drop the two 2lbs i cant get submerged. About to make a big change with now one piece 7mm suit and steel tank. As a starting point how much weight should i drop from my belt? then ill do the float test with 50bar in tank after a dive. Thanks

I know this is an older video, but I hope you review your Poseidon Cyklons. I recently purchased a set and would love to get your opinion on them. This was a great video. Thanks

Please show a video on how to apply the antifog film or the freedom film

This is great information. Believe it or not we've been diving (all recreational) for 30 years. I've never really looked into backplate systems before but am looking to change up my BCD for a more travel friendly lightweight option and this is looking like the ticket for me. Plus I am now semi retired, so we're diving more and am doing much more underwater photography so again this looks like a much cleaner solution. Thank you for all the info. Great stuff. 🙂

Can you dive in egypt with a drysuit i see many people wearing one when diving egypt ?

Hi Mark,thank you for making all these greatvideos, they are so helpful that I watch them again and again whenever I’m thinking of changing my setups. Best regards for you.

what a pansy

why no chest strap?
