Ask Engadget: best 'invincible' point-and-shoot camera?

We know you've got questions, and if you're brave enough to ask the world for answers, here's the outlet to do so. This week's Ask Engadget inquiry is from Mark, who's in the market for a heavy-duty camera. If you're looking to send in an inquiry of your own, drop us a line at ask [at] engadget [dawt] com.

"Back in 2009, you asked what the best rugged, waterproof point-and-shoot camera was. I'm looking for the same thing now and wondered if the readers had any recommendations. I'm not interested in a normal point-and-shoot with a waterproof case, I want something that's waterproof, sandproof, shockproof, that's idiot-proof, with a reasonable optical zoom and with minimal shutter lag. Hope someone can help! Thanks."

Firstly, thank you for doing your homework! It's reasonable that we should swing past this topic again after three years, so what about it dear friends? A point-and-shoot you'd be happy to take dirt biking, snorkeling and won't break when you drop it. Any you've bought yourself that's withstood your lifestyle, have you found any that you'd warn us away from? Let us know in the comments below.
