Keep in mind the different uses for the full flutter and the modified flutter. A full flutter is a pretty good way to gain powerfull propulsion in situations were you are not able to care too much for the environment. Which is why, propulsion in caves are usually solved by frog kicking...

A full flutter usually gets power from a locked knee and use of thigh/hip musculature. In a modified flutter, the hip is locked and the motion works exclusively on the "sunrise" side of the leg. Typically from 10-2 on the clock. Ankle is usually kept relatively loose on the upstroke and a slight...

Slow down. Try to actually stay still and have a look around and "feel". Discover your surroundings. It is very easy to get "tunnevision" and a very strict tast-focus in classes. (That is normal, and if you can't get past it, dont worry). Just slow down enough for a little while to feel and...

Personal opinion, you get an instructor to travel to you, you get to cherrypick two weekends and get really good instruction... it costs what it costs. Only you know your budget and what is "reasonable".

Personally… I do two+. It depends what kind of suit you will use. Trilam or neoprene. But, always bring double sets. A drysuit is only as dry as the next potential leak. They get fewer with your own suit, but it is nice to have new dry undergarments in case of a leak on a class. Water is 3-5c...

You'll be in good hands with them. They have been in the game a loong time. Nothing to be scared about. Go slow. Eat a good breakfast (and bring food with lots of calories. Chocolate, grans warm chocolate with sugar and H-melk, Plenty proteins in the morning, and lots of carbs during the day)...

Were in Norway are you taking your course? And which agency?

Why not just tune the apekses to where you want them? Have used the lot of apekses from Tec3 to US4 to DSTs with the range of second stages on dives to 75 on open circuit and 100 as bail out regs on ccr. Calling this a depth issue is looking at the wrong problem. Keep your DSMB out in front...

Finkeepers are 6-10$... not gonna break the bank. https://extreme-exposure.com/fin-keepers/

Oh, btw, men and women have different centres of balance. Speaking in extremes, the A shape with buoyant hip curves and relatively small lungs tend to make women "top heavy" with a resulting feeling of toppling over in flat trim. End result being a very upright trim. Men, with larger lungs, and...

A few things come to mind. Do NOT ever! Use only drysuit for buoyancy. Especially when newbie. Yes it is simpler to deal with one source of expanding gas, but: If you ascend in an emergency, or inadvertantly, or in any kind of way were you are not in control, you will end up vertical on the...

Do you dive a drysuit? How tight are your seals? Tight seals can cause both swelling in hands and a feeling of anxiety/dizziness.

Have a range of different Apekses. xtx50, dst, tec3, xtx 100, xtx200, atx200, DS4. Do regular diving in Norway from -1C Normally winterdiving is 2-4C. Never had an issue with any of them.

D12s D7s are too small for tech/cave and D10s are horrible to trim out.

Keep in mind that in addition to PPO2, gas density and CO2 will also greatly influence your safety on deeper dives. Have a look at Simon Mitchels table of divererrors related to gas density in rebreatherdivers. While this table is specific to reabreathers, the consept of higher WOB is still...

As an anecdote. I had exactly what you describe. Subq emphysema, krepitous airbubbles in the skin on my thighs and upper torso after I sat down i a very hot hottub after a day of diving in very cold water. Not the smartest thing. Lets just say that water of life was involved... It disappeared...

Yes! The 60 is overkill on the D12s. Get a 40lbs wing. The 40lbs will get you through at least 3 stages with no issues. A 60lbs wing is a hassle on the 12s

Coming from one who has used all but the 10s in Norway. D7 300 bars. I love them. Small, relatively light, very nicely weightdistributed, but shorter than 12s, so mos people find that they cannot rest them on a bench. Compared to a 15l they will have a smaller and more stable profile. D8,5...

As background info: the MV Legends is run by ScubaSeekers, owned by amongst others Sameh Sokar. A through and through very decent, very safetyminded and extremely competent technical diver, and a GUE CCR2 instructor. You should be in very safe hands there. Give them a ring and ask whatever...

Personally, I try to accept that crew have procedures to adhere to. For instance, I was on a live aboard where I was told by my guide (this was a "I want to introvert, I dont want to deal with other people, so I rented a buddy" kind of trip) that the crew HAD to check that your valve was open...
