as a advanced certified scuba diver......i wonder how many ppl will soon die after buying these dangerous to use without proper training units.......well done video....and i agree with you that ppl will still buy them anyway........the general public with no training are at huge risk to suffer injury and or death using these units with no dive training.......so many of these videos show ppl diving alone with these as well......never dive alone and especially with a unit like this.........and so many other factors that make me worry how many ppl will die with these

these would also be good to have as backup if your freediving and someone blacks out and sinks to the bottom or gets stuck, you can air to help cut them loose and bring them up

I am a full time commercial oilfield diver, ex-Royal Navy and also a certified scuba instructor. I can say that we professionals in professional dive companies would never purchase or use Chinese made dive equipment. The Chinese have manufactured some very poor copies of dive helmets and spare parts - they are dangerous. I have a term for such stuff, NQR - Not Quite Right. It may look right, feel right and work right... and then it fails and you find it was NQR all along. My advice is to avoid these. 🇬🇧🇬🇧🇬🇧

i think some of these would have value to dry cave explorers, who have either found underwater spots within those caves, or as an emergency air source when the cave floods.

Thank you for safety instructions Mr ❤

Your video is very intuitive. The main reason I watch this is that I scalloping every year. And I was looking for something to dive and stay undwr the water, even though we are in like 6 to 8 feet of water, which is pretty much a joke for this apparatus. Just wanted to talk thoughts on that.

I appreciate your review on this, and your straight-shooting reviews... Have you considered doing a review on above water air supply systems? I am going to buy one... and likely a parachute tank to go with it.

A great video, thanks so much for sharing 👍

Thank you... I'm that risk taker, great content. Maybe I'll just go get my certification and skip this step.

Hey Chase! Thanks for the great video sharing your experience and big plus the safety warnings! The affordability of these tanks sure make me and my kids get excited but all the amateurs must first hear about the dangers - just like you emphasize! The pumping experience was helpful, too. Guess Id use a compressor instead of wasting time and money on the hand pump. One thing to note that idiot you mention might have been right. At least from what basic school program tells us. If you take the formula that describes the resulting force on the scuba tank (up buoyancy force and down weight force) its the difference between density of compressed air inside the tank and water around the tank multiplied by tank volume times g (9.8 m/sec2): F=(P_air-P_water)*Volume*g. So roughly if water is well higher density than compressed air in the tank the resulting force is up. But now between the 1L and 2L tanks what matters is the volume of the tank which is the multiplier in the formula! In other words you get twice the force pulling that tank up when you increase tank volume from 1 litre to 2 litre. I might be wrong somwhere but hopefully not too far :)

And thanks for the hand pump, I thought it would be like blowing up a balloon.)))))))

Yeah, the closest I've ever gotten to diving is Shark Week on the Discovery channel. Very informative video, I must say; almost makes me want to dive...almost.

So i am a certified diver and am looking at the smaco 2l tank. It looks the most like i am used to with the presure gauze in the usual spot. I wil be using it for snorkling. And it wont replace my proper set. But this would be nice and porteble. Of course the tank will get all the yearly checks and i wont be using no scetchy aircopressors. I have my local dive shop that will fill it with proper air. I love your video and keep up the good work warning the untrained.

Great video, we live in Egypt and practice freediving and a lot and sometimes we dive. We want to buy exactly this, but you opened my eyes and now I know what not to do. I would definitely make the mistake you pointed out when climbing. So the question is, if I go for a breath to maybe 10m and I want to stay there, can I take it down and start underwater? Or do I just have to start at the surface?

Great job defining everything, considering Saftey, human nature/logic, equipment use. you are either an instructor or dive master or should be.

I’m no diver but cool that these exist, didn’t know they made anything like it

Regardless of common sense people ARE going to use these tanks and the safety information will likely keep someone from injuring themselves so thank you. As one of those people without common sense, is obeying the 25 foot limit something where surface intervals should be considered in between uses if filling from a larger tank? Or unlikely given the relatively shallow depth?

I really don't think people should use this type of equipment If you really want to experience diving Get certified there is no substitute for certification Although i do know some people that use these death traps for doing light boat maintenance There is No substitute for proper training and yes i really enjoyed this video like all the other fantastic content you share with us Be well my friend and Stay Frosty 👍

pour de vrai, je reve de nager et faire de la plonger, merci!!

really great video.. just love the smart idiots who think the more air the lighter....🤣🤣

SeaC sells a dive watch/computer for $100

Not much detail or new info. Even playing at 1.75x was boring.
