This universal rattle wheel and fish alarm mount is easy to install on your existing plastic hole sleeves. One of the key features of the guide is the ability to keep the line centered in the hole which can also reduce risking it being frozen in. While using the guide, you can rotate the UnderCover Guide completely out of the hole to land your fish. After you’re done handling your fish, you can tilt the guide in the upright position to re-bait your hook and set your line. When you’re ready to drop everything below deck again, you just simply pull the metal pin towards the center of the hole to drop the guide back down to catch more fish. Use the added rubber hook protector when you you are ready to store the UnderCover guide after fishing. There are two wall mount sizes available for storage. Upgrade your wheelhouse and skid house experience with this innovative product!
