Bender just posted some pictures of some cases that I,ve been working on for the past year.These are water and impact proof.The pictures are the prototypes, the main problem has been getting the switches to work. This has now been solved. Hope to have them available for people in the next few weeks. The best thing is you can wear them on your wrist and read them while you sail.These have survived crashes of 40kts. I hope to sell them for around $30 or I happy to help people make them themselves.The bags work well but they won,t fit on your wrist.
