Looking for something different? Tired of night diving? Fluorescence will give you a whole new perspective on the world beneath the waves. With Tonelife excitation and barrier filters, you can convert your existing lights into a fluorescence set-up. No need to purchase expensive specialty lights or guided dives. Be the explorer!. Why yellow mask filter? This is because unlike UV, blue light is not invisible to the human eye; without the filter you will therefore not be able to see the fluorescence because it will be overwhelmed by the ambient light. 6.1" Wide, 2.56" High , 0.12” Thickness ; Adjustable Elastic Cord Length: 53cm / 21 inch. Fits over Dive, Scuba, Snorkeling Mask. ACRYLIC / PMMA material!!.
