I have no idea what a tip up is, but if it's not listed in the regulations as being illegal, it's legal! No law degree needed.
So here is my legal opinion...propaganda included. Only one pole is allowed unless you have the two pole endorsement. Nothing is said about tip ups. The pole must be in your immediate control. So one could fish a pole and a single tip up or two poles or two tip ups. As long as all are in your immediate control. So what is immediate control, 10, 20, 30 feet. I have heard in the past tip ups were specifically excluded. Since they are now not but also not specifically allowed it is a matter of opinion. One which will probably get you a ticket which you could reasonably fight. Please note I am not a lawyer this is probably propaganda.
Thanks olsy! You found a definitive answer. You can use put to two tip ups with a two pole endorsement.
