Why on earth they use 304 stainless steel for the blade that's absolutely not suitable for marine use as opposed to 316 that's far superior???? Only one thing comes to my mind - if not maintained after each use rusty knife quickly going into bin in order to buy another one! Make sure you wash both the knife and sheath (most people forget salt water stays inside and corrode blade) throughly then apply silicone grease. "However, 304 stainless steel does have one weakness, and that is it does not perform well in chloride environments, in particular, seawater. It is susceptible to corrosion in these cases. If marine corrosion is a major concern, a better choice would be 316 stainless steel, which has 2 percent molybdenum added to it." What a waste of material... am still looking for a dive knife that will do its job and last long...
I decided to get the Aqualung Squeeze Titanium Blade although wish they made these with blunt tip... only like this one, 304 SS version has it which is a shame cause don't want SS at all but want a blunt tip so it's an unwanted compromise for me.
I had the HD200 and sold it. The large air cell has a large airless gap at the bottom due to the shape of it. This sacrificed my trim. I bought a donut style air cell and never looked back. For the ultimate trim and minimum bulk just get a plate and some webbing.
Let's say the boat leaves you and your friend. Both have the rear inflation bcd's. Will they get so tired of trying to stay upright they'll tire out ending up face down?
If you're having trouble staying upright and you're going to be there for a while I imagine you could unclip from the bcd and adjust your position more dramatically. Would still be able to keep your regulator in while hanging onto the BCD like it's a float or laying belly down on top of it.
@atomic_wait Appreciate your response. Just tried one at the dive shop.. they let me get in the pool. There's maybe a 5-10% difference in jacket vs back inflated as far as the pushing you forward goes. It's really barely noticeable. I bought one. Cheers mate! 🍻
@atomic_wait It will take up half the space my jacket took and probably weigh half as much. Once it's dry from diving in a pool today I'm curious to see the weight difference. It will dry faster than a jacket too.
This is the worst description of determining the correct weight and conducting a weight buoyancy test I have ever seen. They are forgetting to describe the equipment you should have on and if the BC should be fully inflated, deflated etc. This video is a disservice to a novice diver.
And nothing is mentioned about how your mask and body position should change, depending on how much of a breath you have inhaled and held: 80%, 50%, 20%.
Step one…get rid of the yellow death hose and strap a 7’ hose onto the rig…learn to long hose primary donate if you really want to up the safety level of your diving
Never seen any reference to rinsing Aqualung ACD regs with the cap OFF (including AL's user manuals)...unless you have a citation to a source for this, I'm calling foul 🤔
As an instructor, in situations where I give air to one of my dive group by my octopus, i experienced it to be a lot easier to have the octopus hose on the LEFT side, the hose will less get twisted. So there is NO fixe rule what side the octopus should be. You set up the gear by experience. Your dive buddy will notice anyway as you guys do a pre-dive buddy check, right? 😊
Two items, 1 The hard sole boot is better as it supports the fin strap as I have used soft boots and the fin strap has worked down and my fin has come off, 2 the zipperless boots are great to get on, a bugger to get off as they tend to suck to your feet.
I'm a bit confused by this video. Presumably, when you say jump in the pool with no gear, mask and snorkel you need to weight yourself UNTIL the water level is halfway up your mask? Otherwise, what is it telling you? BUT if you do it with no kit won't you be overweighted with a cylinder (Steel one at least)? I know I am... If I jump in the pool with no kit on I would need weight to sink to that level, but with a 12L cylinder on I'm very negatively buoyant in pool water.
I have been looking for this explanation/advice for the last hour. Thank you. The pocket on the M/L Frog Plus is comfy, but my boot goes all the way in. Just ordered a smaller size. Thanks for the help. 🥳
I wonder how the light temperature affects the vision under water. 6500K is a cold white, where 3000K is yellow. I would like to know if the yellow light would make the colors seem more natural because reds & yellows don’t travel deeper? What Kelvin do you recommend for a dive torch? Thank you.
Thanks for this video on a very important topic. My question is: do you want neutral buoyancy at the start of the dive OR do you want neutral buoyancy at the end of the dive (4-5 lbs more weight needed assuming 1000 lbs final ascent pressure) ?
