MyFishFinder.com Just like iceshanty but warmer
Another general rule I go by when testing early ice is with my spud (your's may be different-disclaimer) will penetrate about 2 1/2 inches of good ice. If the spud goes through first crack, I back out very gently. On new ice I test the ice thickness with a healthy whack every couple of steps. Others may have other suitable methods too.
Bless the newbie who keeps the sport alive and witnesses us old timers so we maintain an air of mystical reverance. ..........sorry I got all taken up with myself.
I have been using a spud bar for the last 2 weeks. For me its faster, and lighter, then my Jiffy 30 in the 6" of ice I have been fishing. Here soon I will be moving on to Jiffy. Been looking at getting a Nils for this early ice. I am pretty sure that Ace here in Laramie has them. I will look around and let you know. I think 2.5" per whack is a fair estimate.
One wouldn't want to be off on their whack!
Especially if they are a whack job!!
Check Murdochs in Casper, Big R in Riverton or Hasco Industrial Supply. Are you a farmer Jopes? because that's farmer rod.
