People can’t keep a proper size Walleye AFTER it hits the top of the hole. I have little faith anybody knows the size of a Pike or Muskie when that spear leaves their hand.
Although I have to agree with you Dutch, the key here is if you are unsure, the spear doesn’t leave your hand.
Same as shooting roosters only
Drake Wood Ducks only (boy that’s an old one)
Bucks only
Personally I haven’t speared one over 3-4 pounds (back in a day) but there are some days you’ll see a lot deep and other days nothing. Three was the limit back then.
