Hi there, must mention the phone case that might be the best worth the money on the market it’s about 30£ with a few accessories small anti-static wipe self adhesive rubber phone holder user guidance tips … strong lanyard plastic opener for metal fasteners the phone case is quite versatile and suitable for iPhone and Samsung phones, with outer dimensions of 192 mm x 109 mm can fit easily iPhone 6 to iPhone 12 max pro or Samsung 6S to Galaxy S21 Ultra as a example, its mine Samsung J6 compare to S21 Ultra Well-built shell case taking picture button tripod attachment looks quite sturdy tried to bend a bit of protective screen foil gives a bit impression as thick plastic foil i may say the fasteners of the case are well built even though they had a pro closing mechanism phone size adjustment you will be abe to adjust the phone depends the model or preference taking pics button can be adjusted on both sides – left or right-hand side plus height adjustment button adjustment depends on the orientation Those two dents need to be matched up with other parts of the case on the bottom also might be extra careful regards how to properly close the case I personally am doing it gradually after closing it the mask will capture the air inside the case That’s how its works before you submerged the mask recommended to test it normally the reference of the mask says 15 underwater which means you have to be an amateur scuba diver just a normal human can dive about 6 meters (a thinner human if you ar more buoyant will be harder 🙂 if you tried to research about effects of pressure on different depths you will come up with some numbers but most importantly that means you will not be able to stay underwater for a long time on recommendable depths (Case) i just read a comment from David Smith he states: So 1-metre depth is a pressure acting on a body of 1.1 bar and 5 meters is 1.5 bar so the ratio is 0.7333:1 or 11/15ths.
So 15 hours at 1 metre would be equivalent to 11 hours at 5metres so my understanding is diff lengths of exposure on small depths can equivalent to bigger depths to a little be less for a less time as a reference, I just take pounds per square inch on a 6-meter depth which is an amateur swimmer can dive psi is equivalent to football 8.5 PSI recommended by FIFA if ur able to resist pain in the eardrums some people can dive only 3 meters and the 16meters depth of 22.8PSI is equivalent to a car tire PSI … in a future, I will try to test on certain depths this case but my doubts are probably the depth this case can withstand is no more than 3 meters with a short period if u have any thoughts or want to share your opinion just give me a shout hopefully enjoyed the video dont forget to LIke and Subscirbe
