SolunarBass
Know exactly when fish are biting. Plan your trips with precision using solunar theory and real-time weather data.
The Science of Solunar
Solunar theory, developed by John Alden Knight in 1926, correlates fish and wildlife activity with the position of the sun and moon. When gravitational forces align, fish are more likely to feed.
Major periods (about 2 hours) occur when the moon is directly overhead or underfoot. Minor periods(about 1 hour) occur during moonrise and moonset.
Combined with weather patterns, barometric pressure, and local conditions, these predictions help you fish smarter, not harder.
