Drop shotting is a finesse technique so a good setup is on a lighter, sensitive spinning rod and reel with 6-10 lb test line. Tie on your hook using a Palomar knot leaving a good length of extra line (18-24 inches). If you need a good explanation for this knot (or a huge variety of others) I highly recommend the “What Knot” App from Columbia Sportswear (free for iPhone – What Knot to do in the Great Outdoors). It contains illustrated step by step instructions for a huge variety of knots for fishing, boating and climbing.An appropriate sinker is then attached to the tail line. Distance from hook to weight of about 18 inches is a good start but can be varied depending on a number of factors, for example, if you are trying to stay just above the weeds. Good electronics can now distinguish the weed tops from the hard bottom and can be a useful guide here. Where regulations allow, two hooks can be used on the line spaced out at varying distances (in Ontario (2014) a line may not have more than four hooks). Possible baits include, live bait, wacky worms, various soft plastics, flies (a muddler minnow would be good choice).
Cast to target and let sink while keeping enough slack out of the line to feel a strike. Let sink to the bottom. Still fish or slightly jiggle the bait without lifting the weight off the bottom. Maintain a taught line to feel any strike.
The drop shot rig is good for depths of 5 ft or deeper with more weight needed the deeper you go. For shallow water fishing (3-5 ft) its likely better to fish the type of plastics shown in the figures without a weight.
