I first seen Hali jigs when we were on a North Dakota trip 3 yrs. back. They worked great for the perch we were out there for.....This worked of us.....Just let it fall to the bottom, let it sit on the bottom, lift it up real slow from the bottom and feel for any extra weight........90% of the time, we had a fish on without any notice except for the extra weight feeling. Set the hook........The perch were really on the bite at that time though....... We caught our limit that morning in no time.... When we held it above the bottom maybe 4-6 inches. We had to wait a lot longer between bites.
