A few people have asked me if we are leaving them in all winter. The answer is no. I.L.M. will be coming out within the next week or so to remove them for the winter, then replace, calibrate, and hopefully correctly position and anchor them in the spring. This year was not a good test of their effectiveness due to the lag time before they were fired up as well as the lake condition when they were started. Next year (hopefully) will be a good test.
