Trolling is the number one fish-catching method for anglers fishing from a boat. It gives a lure or bait the natural action that entices a fish to strike. Trolling is a basic fishing method to search for and catch fish -- many kinds of fish in many different situations. In The Troller`s Handbook, Ray Rychnovsky starts with the basics, works up to the advanced methods, then, by incorporating mathematical theories he used as an engineer in the field of aerodynamics, brings trolling to a whole new level. If you find partial differential equations to be a bit intimidating, have no fear, Ray does an excellent job of explaining how they apply to trolling, and guarantees to greatly improve your trolling success. You will learn: trolling for many species (salmon, trout, exotic ocean game fish) in both fresh and salt water; back-trolling; high-speed trolling; using lead-core line and downriggers; learning depth; reading water; boats and tackle` using the Black Box; many useful tips; and more. Ray`s clear writing and easy-to-use graphs (the first complete set of graphs ever published showing how to troll at a desired depth), will help you become a more successful angler in both fresh and salt water.
