Just wanted to thank whoever it was that suggested that i get an Aquapac for my GPS. Never paid much attention until it gets seriously windy.
After getting the catapult of the day, rag doll style (according to the boys on the beach) I surfaced from about 3 feet down, turned around to look for my gear and spotted my GPS floating about 5 feet away safely warm and dry in its Aquapac.

I realised i hit with my right shoulder and the force of the water tore it straight down my arm and off. No bag, no GPS.

The best part, turning it back on and reading 34.1 knots on the display.

So if you have a GPS put it in something that is waterproof and floats.
