Sunscreen and Dive Computers

Because sunscreen is so often in proximity to dive computers, we would like to share some advice from our service technicians. There is at least one well documented study regarding polycarbonate cracks caused by sunscreen and similar studies of other products such as hand lotion. Many dive computers use a transparent polycarbonate plastic faceplate (aka "Lexan"), rather than glass, to seal the computer body yet permit viewing of the LED display. While sunscreen causing an actual crack in a dive computer body is unlikely, repeated sunscreen exposure can cause hazing or distortion of the clear plastic faceplate, thus blurring the display. We advise making an effort to avoid touching the faceplate of your dive computer display. If you suspect there might be sunscreen or lotion on your dive computer, because these chemicals are often water resistant, after your dive trip you can use baby shampoo or mild dish soap to gently wash the faceplate.
