Of course,under the deep twitching in order to catch a perch should be understood fishing at depths of 2-3, 5 meters. Rarely deeper. Most of this fishing occurs in the shallows or edges, where bass like to hunt their victims. An important factor in the choice of location - a hard cartilaginous bottom of the roll or the edge. On a soft perch or stand and hunt dislikes.
Bait for fishing in such places - jigs with a sinker weighing from 4 to 10 grams ( depending on the strength of the flow), and wobblers. Let's focus more on wobblers.
For our purposes,it is best suited Wobbler class shed min or DNA with a body of 60-70 millimeters and globe immersion to 2-2.5 meters.
My favorite crankbait for a noob Lovely - ZipBaits Khamsin 70 Dr ...
and Yo-Zury Hardcore 60 DR.
The first is up to 1.5+ meters deep, and the second is up to 2+ meters.
Animation of both models is almost the same. Casting downstream (along the edge or rollover), sinking the bait on the operating range of several revolutions of the coil, and then the jerk wiring with pauses and recoil bait rod downstream.
Just posting this technique when fishing for bass was off in his story Valery Novoselov - expert Spinningline. Worth a look and listen to his story and comments...
