Deep Sea Fishing Security: Why You Want a Trench Bag and What to Pack

Offshore saltwater fishing is a well-known type of fishing off the coast of the United States and it’s easy to see how attractive it is. Access to secluded fishing grounds, a test of the skill and thrill of catching large, powerful wild fish. But with the reward comes a risk.
