Lake Nipissing Walleyes like a slow jigging motion.
Rest bait on bottom, gently lift 6" - 12" hold....repeat.
Use a tip-up also.
The Windlass will keep your line moving, but sometimes they like a dead stick presentation with no movement.
Buy medium size shiners ( 3").
Use jigs, chartreuse, green, and yellow seem to be the best producers in 1/4 - 1/8 oz.
Also use plain hook on tip up if they don't hit the jig.
Don't be afraid to use scent on the bait as well.
