Underwater

The TX20 survived my testing according to its specifications. That included three 60-minute periods in 2 feet of water (it's rated for 16 feet) and five drops straight down from 5 feet onto 2-inch plywood. Of course, this doesn't mean your results won't be different; rugged cameras are tested to survive very specific things and even using them within those parameters can cause damage. Regardless of a camera's ratings, make sure you read the user manual for caution and care instructions.
