This is simple. Planers catch fish. If you are not fishing planers in near shore waters where there is reef or bottom structure, you are probably catching a lot less fish. You need to get baits down 30 feet, or so, to cooler waters where the fish are hanging out, especially in temperate areas. In deeper waters where you might find a floating tree or debris, many times wahoo and other pelagics hang out 30-60 feet down. If you are not putting baits down deeper, you are wasting your time.
