I'm a Dive master & been diving for 30 years. I was a Bubbles customer until it closed down. I visited Grove Scuba the 1st. month that opened next to Burger King. I had a Burger King cup with a lid & water inside so the young inexperience lady working there told me I couldn't be inside the store with the cup. I turned around & never looked back again.
I didn't know a cup of water was a hazard to all your waterproof products.
