Superbly illustrated and highly informative, The Sea Angler's Step-By-Step Guide to Baits and Rigs is the best book on baiting-up and rig-making I've had the pleasure to read.
Through its pages you'll learn how to make up rigs for shore fishing and boat fishing from the simplest to the most specialised, and all in enough detail to answer any questions you may otherwise have had - just take a look at the main topics listed below.
In the second part of the book you're introduced to the best natural baits around, along with details of where to find them, how to collect them and - most importantly - how to mount them on the hook so that they won't fall off.
The book's title - The Sea Angler's Step-By-Step Guide to Baits and Rigs - says it all.
Downrigger ~ The cranelike device incorporating a line-counter reel often seen on the sterns of sport-fishing boats, which lowers a trolling weight on a wire line to a pre-determined depth. The trolling line is attached just above the weight, which gets the lure down to depths that would otherwise be unachievable.
