Keeping contact with your jig all the time, learn your location (the floor where the hole, mussel beds, known hang up location) and staying focus 100% of the time is what will keep you from loosing jigs.
The weight of the jig is not what cause more hang up.
The weight of the jig is to match the current speed for proper sink ratio. Another word, getting the jig down to the strike zone as fast as possible without dragging the bottom but also keeping it in the strike zone as long as possible. This is a balancing act with selecting the proper weight. This is accomplished with experience and practice. That’s why being 100% focus is and understatement at times.
If the jig is dragging the bottom, it’s too heavy. If the jig is not falling into the hole, it’s too light. You have to stay focus all the time. You have to have a mental note of what the jig is doing down on the floor. The only way to have a mental note is staying focus and keeping contact with the jig 100% of the time. The second you loose contact with the jig, the potential for hang up increases.
