Upwelling events drop California water temperatures by 10-15 degrees in a single day. Why they happen, how to recognize them, and the tactical adjustments that produce fish during sudden cold water rather than waiting for conditions to recover.

Knot work is one of the most underrated skills in spearfishing. The five knots that handle 95 percent of rigging, line repair, and emergency situations - and why every diver should learn them before depending on them.
