Hi FireMonkey,<br><br>I didn't go that deep with my Photon II and it was normal fresh river water but my Photon II survived also although it was also dimly lit after it was submerged in the fresh water.<br>Opening it and drting it with an hairblower brought it back to normal functioning.<br><br>Your last remark about knowing no non LED flashlights surviving 2 atm. well just get yourself any UKE (Underwater Kinetics) flashlight from the 2 AAA mini keychain model up to their biggest models and you'll find that they probably can stand the atmospheres better then you do ;)<br><br>I have a friend who I gave a 2 AAA UKE and while on holiday diving he took it to 100 feet without any problems whatsoever. The best part these UKE's don't need drying of the inside after submerging them ;)<br><br>Best Scouting wishes from Holland,<br><br>Bagheera
