will this keep my cell pone and passport dry under water for longer periods ?
I thought this was perfect for keeping all my stuff dry and handy on a dive boat. I could see everything so I didn't have to root around for it. This is the second one I have had and the second one that the plastic tore near the top. It looks sturdy enough, but I might buy something else next time.
I would say, No.. It's just a fold over dry bag, not a ziplock type..
Yes. Has an overlapping plastic section and the velcro on the inside. Put in your items, close the velcro, and roll it up to keep everything inside dry.
I have not used it as a submersible bag however I have taken it on boats that was both fishing and scuba diving boats, I had several items inside including my wallet and cell phone and everything stayed dried, the outside was pretty wet but everything inside was dry, no water seeped in.
There are other items that would serve that purpose better. It is not designed for submersion.
While it is waterproof, I wouldn't take a chance, but I'm a little chicken that way!
This bag will keep your valuables dry while mixed in with wet scuba gear or during a heavy rain. It isn't designed to really go under water.
The bag material is waterproof, but it will not prevent water from entering at any significant depth. I would also not recommend it as a solution for keeping your materials dry if you will be intentionally submerging them for a long period of time. A dry box/case would be better for this.
Did not use the bag under water. Used it for dry storage of items on dive boats only. It works very well for that.
I wouldn't try it. For cell phone (and not for diving, only shallow water use), I'd check out Sealline's ecases.
