There are several things you can do.
1- Drag adjustment. A light drag will stick a crappie and save your gear.
2- If you are fishing a bottom bouncing rig, use a lighter snell line, if the
hook is hung you only lose the hook or jig and keep the main line and
sinker.
3- You already did the 3rd and make sure your rod is set well. You lost the
upper have, but saved the reel and the rod butt.
Don't frett, if your not in the cover then your not in the fish. We all have done it. Good luck.
