I have only paid attention to it a few times and my review is mixed. One day on a Coues deer hunt I had seen very few deer all morning but the solunar table predicted 12 noon as a "high acitivity" time. After not seeing deer all morning I was did not expect much but a few minutes before noon I saw a doe and fawn heading to water and in the next hour I saw over 30 deer! While guiding early elk hunts all of September I would check the solunar table in the afternoon. Most days I would hear the firs bugle withing 30 minutes of the prediction. I have just as many days where the table does not seem to be anymore accurate than throwing darts at a graph though.
