Am I correct in the assumption that two very bright search lights will not "blind" the FLIR unit? It is common for the Tugs on the Gulf Coast ICW to run two 1 mile plus search lights on all of the time--usually on the banks ahead. They are absolutely blinding for night vision--and currently I slow and pull off the ICW where one of these guys comes along. Like Pascal, I have several nights on the Atlantic ICW running all night, and multiple on the Gulf Coast ICW. On the Atlantic, there was no traffic, and we just used a spot light to pinpoint docks, banks etc in narrow areas. In the long reaches the radar caught the next marker (this was before Chart plotters), so a bit more of a challange. But currently we also run with two independant chart plotters.
At $4495 the the FLIR are becoming more "afordiable"- Also apparently the Navico Broad band radar is shipping (?)--so that is another very good tool for close up at night. Once you start looking at any LCD screen-no matter how dim or what color, there is significant loss of night adaptation-and that is why we assign one person only to watch the water ahead....
