    Use tips
    Two waterproof bags are always more effective than one, because if one of them gets into the water, the other can still continue to play a waterproof function
    Different waterproof bags have different uses and should be targeted for use. For example, the phone can be placed in a clip-on transparent waterproof bag, and the clothes can be stored in a simple roll-up waterproof bag.
    Old and even holed waterproof bags still have their use value. They can be used as abrasion-resistant layers of waterproof bags, because even thin waterproof bags are relatively easy to be hooked even if they are completely waterproof, and an additional protective layer is naturally safer.

    Misunderstandings about waterproof bags
    Many users will mistakenly use the waterproof bag, thinking that the air in the memory can be forced to achieve the ideal waterproof effect. In fact, when using the reel-type waterproof bag, it is necessary to maintain an appropriate amount of air in the bag to help seal the reel. And once dropped into the water, it also has enough buoyancy to not be lost.

    In addition, except for special-purpose waterproof bags, general waterproof bags are not suitable for underwater use, because even if the water depth is only one meter, the water pressure can force the waterproof bag into the water, so try to keep the waterproof bag on the water surface.

    Maintenance of waterproof bag
    Regardless of any form of waterproof bag, proper post-use maintenance is necessary, especially after carrying out marine activities, the salt in the seawater is very destructive due to the seawater soaked in the bottom. If it is not cleaned in time, it will often The fibers and gums of the bag are damaged, making it fragile and easy to wear, and the biggest reason for the waterproof bag’s failure is that the line of the car breaks and causes dripping, so cleaning the seawater is the key to maintenance. After each use, please rinse thoroughly and dry in a cool place, because the strong sunlight can also cause the rubber edge of the car line to age and cause water to enter.
