The Tady 9 is a thinner and more narrow version of the Tady A2 and Tady AA jigs. This makes the jig fall faster due to less drag on the lure. It also swims in a tighter pattern for when you need to burn it back when fish are the most active. Verticle: To work it vertically, cast it or drop it straight under the boat. Let it sink to the desired depth which could range from a few feet to several dozen feet. Put the reel in gear and wind it back with a fast retrieve. Horizontal: Cast it as far as possible and let it sink for a second or two and wind it straight back to the boat with a fast retrieve. YoYo: Cast it or drop it straight under the boat, let it sink to the desired depth, and one line is taught and the reel is in gear, drop the rod tip and then lift the rod tip 3-4 feet. Drop the rod tip again and repeat without winding the reel. After a few minutes if you're not already bit, wind it up a few cranks and repeat.
There is no need to put any bait or scent on most Tady jigs, it's a reaction and if the bite is on, they will eat it. Bait can actually impair the action of the jig so it's best just to tie straight to the ring on the iron. We prefer throwing irons on 30# or 40# line in general but the size of the fish being caught, the size of your reel, and the weight of the jig all play a part in deciding what line to use.
Color and hook manufacturer varies on each lure and may not be exactly like the picture shows. Scratches are common on all Tady Lures, they get scratched in transit and these scratches don't impact the ability to catch fish.
