Question

how far from the shore will you start seeing fish to spear?

Answer 1

The very best free-diving spearfishers can hold their breath for durations of 2-4 minutes and dive to depths of 40 or even 60 meters (about 130 to 200 feet). However, dives of approximately 1 minute and 15 or 20 meters (about 50 to 70 feet) are more common for the average experienced spearfisher.
