We purchased the complete pro package at the trade show in Atlantic City. After watching the videos on the Leaktronics website, I thought I had a handle on the equipment and I probably could have learned by myself to use it, however I’m glad I went to the hands-on training. The creation of “controlled leaks” in an actual swimming pool and locating them with the equipment was a great learning experience. The on-site leak detection was an even better experience, as the leaks were able to be heard, and those that weren’t leaks, weren’t heard. It was simple to see as they were “true leaks.” I feel I have a better handle on the equipment, and I am confident in the fact that I know a process to work through on each site and that I know what I am listening for, then verifying by sight afterward. Thank you!
