For SAR I still carry my Petzel zoom in my pack. Throws great light for seeing things 30 feet away. <br><br>I have switched to a Princton TEC combo headlamp. It has two lamp assemblies, one 3 bulb LED and one incandescent. The lamp assemblies have a notch so you can only install them in the body of the flashlight one way. I am able to switch between the two assemblies with my eyes closed. <br><br>It is waterproof to 2000 feet. It uses AA batteries. I use lithium batteries. <br><br>When searching I use the incandesent lamp and around camp or command center, I use the LED. It is maybe double the size of the Tipka/Zikka but I have both incandesent and LED and waterproof.
