Hello,
We recently purchased a pair of your green underwater laser pointers for use in our research. We needed a way to determine the scale of images on our underwater camera, and mounted the lasers on the camera frame for that purpose. As the packaging for the lasers states that they are waterproof down to 300 feet and the lower bound of their operating temperature range is 15º C, we were somewhat apprehensive about their success. Our research required the lasers to work for extended periods at depths of 350 feet or more in the Gulf of Maine's cold water, but we're happy to report the lasers performed perfectly. The lasers spent up to two and a half hours at a time at depths up to 370 feet and temperatures averaging 7º C, and gave strong beams that were clearly visible on the video images. In short, your lasers were stellar, delivering all we could ask for and more. We've already recommended them to others who need lasers for similar applications.
Thank you very much! Your lasers have been an indispensable part of our work this summer.
