A fish requires two main points to thrive in a body of water - food, and protection. A well-protected area will provide plenty of shade and cover. This usually means the water will be submerged in trees, brush, rocks, algae, etc. Also found in these well-covered habits is, minnows, larva, incests, and other organisms. Because an ideal environment for a fish includes BOTH food and protection, these murky aquatic ecosystems are typically a hotbed for many species of fish.
It's no coincide that many fishermen tend to frequent spots that are well-shaded. Although fishing in waters that appear to be a good habit for a fish might increases the chance of catching a whopper, the angler should also expect a snag.
When an angler gets a lure down to where the fish are, the lure is essentially resting where a is snag probable. To make matter worse, when a fish is hooked it instinctively heads for cover, and darts further down into the darkness, diving deep where trees and brush are greatly magnified. If a fish cannot be controlled, and it dives deep enough, there is an even greater chance of snagged lure, which can result in a loss of fish and lure.
Although the Snag Buster can't save the whopper of a fish that got away, it could save your lure.
