Plano 3440-10 Waterproof Stowaway (3400 Series)

The Plano 3440 Waterproof Stowaway is a small clear box with one job: keeping the things that cannot get wet dry. It is one of Amazon's top sellers in Fishing Tackle Boxes, though it is not really for tackle. It is for the phone, keys and license that ride along on every fishing trip.

Plano seals it with a Dri-Loc O-ring and three cam-action latches, which is the difference between a dry box and a tray with a snap lid.

The Numbers That Matter

O-ring seal plus three latches. Plano describes the seal as waterproof and airtight. Three latches spread the clamping force across the lid instead of relying on one clip at the front.

7.375 x 4.5 x 1.75 inches outside. Those are external dimensions, and the inside is smaller. Keys and a license go in easily. Measure a large phone before you count on it fitting.

Clear body, no dividers. You can see your keys through the lid, but nothing inside is organized. Tackle belongs in a tray like the Flambeau Tuff Tainer.

Who It Is For

The dad heading out on a boat or kayak with the kids, where a phone in a pocket is one slip from the lake. It pairs with the KastKing Blowbak sling, which is water repellent but not waterproof, and the Plano two-tray tackle box, which is not listed as water resistant.
