If you think it is only a Walleye thing...YEP, you don't understand.
They have been used to catch almost every shallow fresh and saltwater water species.

A repeat customer testimonial:
Denis on the Skykomish River WA
I use jigs with the BulletBobber fishing for steelhead on the Skykomish here in Washing State. I spend 90% of my time on this one river because it has all the runs of anadromous fish with all the species of salmon. Starting in June when the river opens it will have fish in it till the following January when it closes for 5 months to leave them alone while on their spawning beds. The BulletBobber allows me to cover more water with a single cast and is a joy to work with.
