Drying cartridges for HD Hero waterproof cameras (all versions). The insertion ensures that the camera and the interior of the waterproof housing will not fog in cool and humid conditions.
The cartridges are used several times (4-5). The pouch with the ruler has a ready-to-use tag. When the cartridge has exhausted its moisture absorption capacity, it should be placed in a hot air oven for about 5 minutes at a temperature of the order of 150 ° C.
Store in a sealed bag without access / exchange of air. 3 drying cartridges included.
Note It is worth remembering that, although a waterproof case prevents water and moisture from entering the device from outside, changing the temperature and dew point may cause the inside of the camera case to fog up. This is a normal and expected phenomenon. The only way to eliminate this problem are the drying pads. Of course, the inserts do not eliminate the possibility of fogging the camera from the outside - in this case, the casing should be wiped with a soft cloth.
