Lomo Drybox 20 Maxi Size - Sailing Dry Box.

I thought this was a little pricey but there limited options if you want to be sure your electronics won’t get wet when on the water. This size is perfect for an iPhone 11 in a wallet cover, plus keys. Catch seems robust with room for at least two or three more phones if out in group. Smaller size i doubt would have been big enough for my wallet cased phone. I throw this in my dry bag so I’ve not submerged it I entirely but with electronic car keys not taking any chances.

I'd maybe keep your keys in a plastic bag so they don't scratch your screen of your phone, it's watertight and keeps your stuff safe

Haven't tested if it is waterproof

This box is now the central console tackle box in my kayak. It has 4 corner securing eyes making it easy to secure in place with elastics, as well as adding a short safety leash. Will probably be adding a second one for the rest of the spare tackle etc. in the tankwell crate.

We did a mock up of capsizing a jetski, the stowage inadvertently opened and everything came out of the stowage. Everything in the dry box floated, stayed dry and was easily visible on the water.

Purchased to take a Fluke multimeter and it fits perfectly along with the probes and sensors.

Excellent product keeps everything dry. Robust

Exactly what it says on the label :-)
