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
if your wanting an improved experience you can use waterproof shutter,the link u can find it in the description
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
