Green laser sensor can measure up to 150 meters underwater. The green laser distance measure typically operates at a wavelength around 532nm, which is in the green part of the visible spectrum. This wavelength is chosen for its ability to penetrate water with minimal scattering and absorption.
High quality underwater laser distance sensors can provide very accurate measurements, often within millimeters, depending on the model and conditions.
Accuracy of underwater distance sensor can be affected by factors such as water clarity (turbidity), temperature, and pressure. Clearer water allows for longer and more accurate measurements.
