I have a 1976 Pearson 30 with omni gauges and anemometer. The anemometer broke off the top of the mast and I need to either replace the anemometer or the entire system. Since Omni no longer exists I cannot get any information as to a replacement. Any ideas on the Omni specs/replacement or something similar that would go into the existing spaces. The system has gauges for wind velocity, close haul, and relative wind direction. I don't really want to go to a digital system unless I have no other options. Thanks for any advise. Pearson Sailor
