• Prediction information available for all 50 states and Canada
• Displays smooth graphical curve of tide height, times, and current flow
• Displays prediction curve (good for hunting and fishing)
• Displays fish species prediction (selectable salt and freshwater fish)
• Displays sun rise/set times and moon phase with rise/set times
• Displays predictions in monthly Calendar form or daily
• Graph automatically displays and prints proportionally to window size and position
• Uses your printer driver to print in same size, position, and proportion as displayed on your monitor
• Convert LORAN coordinates to Lat/Lon coordinates (and vice versa)
• Calculate distance and bearing between any two global  coordinates
• Calculate unknown LAT/LON, given linear distances and directions from a known place
• Find Global GRIs and Substation        
• Define fish species that can be added to species display
• Define places that can be added to the prediction display
• Select graph time span from 1 hour to 1 year in 1 hour increments
• Select sensitivity for current flow
• Change to DayLight Savings Time and to Half Hour Time Zones
• Change graph colors and line sizes

If your interest in Dr Dan's is solely for LORAN to LAT/LON conversions please read this note regarding conversion accuracy.

All tidal data are based upon harmonic constants and other data as provided by the NationalOcean Service (NOS) and other Oceanographic agencies. All fishing and speciespredictions are based upon data obtained from various Parks & Wildlifeagencies. More accurate species data is very welcome. Please create a SPECIES.DATfile and e-mail it to me for consideration.
