Frequently Asked Questions

AI
Most dry boxes in this category are designed for surface activities, kayaking, and shallow snorkeling. For deep-sea diving, you need specialized pressure-rated housings; always check the manufacturer's depth rating before submerging.
Perform a 'sink test' before your first trip. Place a piece of paper inside the box, seal it tightly, and submerge it in a sink or tub for several minutes to verify the seal is intact.
Both are valuable, but buoyancy is critical if you are transporting keys or expensive phones. A lanyard prevents the box from drifting away, while buoyancy ensures you can actually find it if it slips overboard.
