The Jason is longer and more triangular in shape that its predecessor. We have also reworked the balance of the lure with two 4.5mm. tungsten ball bearings. The bearings are housed in a cavity which sits dead centre on the lure. When you want to cast the lure the bearings slide to the tail of the bait on a small rail. The Jason comes into its own in tight swims where accurate casting and a limited swimming range let you work the lure between gaps in weeds or round sunken trees. The lure is best worked back fast. This modern style jerkbait can be used by experts to get bites even on the hardest of days. The lure has a particularly animated action when jerked as it moves quickly upwards towards the surface then dives down again. This movement is very close to that of panicked prey fish. The lure is slender enough to be worked through even shallow swims.
