Kastmasters are one of my favorite metals to fish because of their versatility and ability to catch multiple species. I have been fishing them in open water for freshwater and saltwater species for years, with great success. Recently, I have started jigging them through the ice. As they penetrate the water column, they reflect visible light and thereby provide bursts of flash. Having flash down low can make all the difference between catching and getting skunked.

During one trip, I was jigging a 1/4 oz Kastmaster in hole that was centered between two holes with tip-ups. I have caught multiple species through the ice by jigging Kastmasters; but this was the first time that jigging a Kastmater through the ice out-fished live bait!

I keep my ice fishing rigs simple. First, I replace the treble hook with a single hook. Second, I I secure a segment of fluorocarbon line to my ice braid via Crazy Alberto Knot. Third, I secure my 1/4 oz Kastmater [https://amzn.to/3g1V0s9] to my flurocarbon leader via double surgeons loop knot.
Kastmasters are intended to be casted and retrieved. But! Fish do not follow the rules. Jig Kastmasters through the ice!
