Quick Answer
Wearing a wetsuit can be beneficial during night spearfishing, but not always necessary, especially in warmer waters. It provides thermal protection and prevents hypothermia in cold conditions. However, it may hinder visibility and movement in the water.
Night Visibility and Safety
When spearfishing at night, visibility is already compromised due to the darkness. Wearing a wetsuit can further reduce visibility by reflecting the light from your torch or limiting your ability to see your surroundings clearly. To minimize this issue, use a low-intensity torch, and keep your wetsuit as streamlined as possible to reduce drag and improve movement.
Water Temperature and Thermoregulation
In cold waters, hypothermia can set in quickly, and wearing a wetsuit can be a lifesaver. In these conditions, aim to stay in the water for less than 30 minutes, and consider wearing a wetsuit rated for the specific water temperature. For example, in water temperatures below 60°F (15°C), a 5mm wetsuit is recommended, while in warmer waters, a 2mm or 3mm wetsuit may be sufficient.
Shallow Water Technique
In shallow water, it’s essential to be aware of your surroundings and avoid disturbing the seafloor. Wearing a wetsuit can help you stay warm, but it’s not a substitute for good technique. When approaching a fish, use a slow and deliberate movement, and aim for a clean shot to avoid missing the target. In shallow water, it’s also crucial to be aware of your depth and avoid running out of air or getting stuck in a position where you can’t free yourself.
