Position your ice rod perfectly. The c-clamp fits onto the tubing of portable fish houses up to 1-inch in diameter. Spinning reels rest in the pivoting rod cradle that allow you to see the lightest bites without using a bobber. When a fish bites your rod tip will move up or down, signaling a strike. Your rod stays secure in the cradle, but is easy to remove when you have a fish on the line.
