Recently updated for use with the latest tablet-sized devices and cameraphones, Aquapac’s 100% Waterproof Cases offer guaranteed submersibility to 15 foot/5 meter depths, carrying straps, and very simple insertion/removal designs.
The larger version, also known as Large Whanganui 664 ($45), has ample space for an iPad inside, a set of three locks to keep water out of its hard plastic top seal, a collection of five moisture-absorbing desiccants, and a detachable, adjustable shoulder strap for carrying in water or on land.

Aquapac’s smaller iPhone version (aka Mini Phone/GPS Case 104, $30) instead uses two locks and a necklace, and has an optically clear back portion for underwater camera use; it doesn’t include desiccants.
