Underwater Focus Lights
Focus lights help you frame the photo and your camera lock focus in the somewhat dim lighting conditions found underwater. They are essential for night diving and some have red lights or filter so that they don't scare shy animals like octopus and crabs. Please see our Light Comparison Specifications Chart for a comparioson guide.
