Ewa-Marine Waterproof Sports Pouches

Two Great Waterproof All-Purpose Sports Pouches!

Here's a question that I answer nearly every week - real example and my response:

The Question:

Hi,

What do the letters "DU" and "DUS" stand for and what's their meaning (if not obvious from your first explanation)? We are looking for waterproof pouches for some gear.

Thanks, (name deleted)

The reply:

The DU & DUS are Ewa-Marine's version of model "types":

The DU sports pouch range is water resistant and may be immersed in water. They will float with your stuff too but they have a sliding rail closure that could work loose in the motions of diving or snorkeling. They are not recommended for diving but rather for poolside, beach or storage in a boat where they may become splashed or fall in the water!

The DUS waterproof all purpose pouches are for diving, snorkeling and active use while in the water. Ewa-Marine has tested and given them 100m / 300 feet depth ratings. The difference is the closure rails that clamp the pouch are secured with lock nuts and won't accidentally be worked loose over time. Your electronics for instance, could possibly be crushed at extreme depths but the DUS would still keep them waterproof.

Within each category of DU or DUS, you'll see "-1", "-2", "-3" or "-4" and that numerical suffix, corresponds to the item and also the size of sports pouch you select that meets your requirements. The higher the number within the DU or DUS range, the larger the dimension of the pouch, the dimensions of each are as listed on our website.

These are factory designations and I don't understand the German language so I couldn't guess if they are acronyms for something or not. I hope this helps. Have a great day!

Best Regards, Yours Truly
