Built for comfort, stability, and hands-free illumination, the Bigblue TDH-2M-XL Dual-Light Dive Helmet (XL) gives divers a streamlined, lightweight platform for mounting two lights with fully adjustable mounts. The ergonomic fit helps the helmet stay secure and comfortable so you can focus on the dive—not your gear—whether you’re running night dives, low-visibility training, or public safety operations.

Recommended Light Setup (what we’ve found works best)
A combination of beam angles gives you both reach and wide coverage:

Narrow beam: AL1300NP (10°) – great for distance, signaling, and cutting through murk

Wide beam: AL1300WP (85°) – ideal for general coverage and situational awareness

Alternative extra-wide option: AL1300XWP (120°)
