Using the pulsed Time-of-Flight (ToF) ranging principle and a green laser, it is designed for underwater environments and features IP68 protection. TW3 is built to handle surface reflections, water refraction, and turbid water conditions for stable underwater scanning, helping devices such as pool cleaning robots and underwater inspection equipment add navigation, obstacle avoidance, and environmental mapping capability.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP68
