Study Notes
Refraction and Spearfishing/Bowfishing
- Refraction is the bending of light as it passes through different mediums, like from air to water.
- This bending of light causes underwater objects to appear in a different position than their actual location.
- This optical illusion can make it difficult to accurately target fish when spearfishing or bowfishing.
- The rule of thumb for spearfishing and bowfishing is to aim low because of refraction.
- The amount of adjustment needed depends on factors like the angle of approach, the water depth, and the size of the fish.
- Aiming 6 inches lower than the visible target for every foot of depth is a good starting point when shooting at a 45-degree angle.
- Practice is crucial to mastering this skill.
- Failing to account for refraction can lead to missed targets and frustration.
