The Patented Fish Fighter™ Anchor Spades are designed to bolt onto your 40lb Fish Fighter™ (Columbia River Edition) Anchor. We designed these spades to help those who fish in rivers that are difficult to hold in, due to an all-sand/gravel or all-clay bottom. These bolt-on spades will really dig in and plow up ground like the head of a shovel. One look at the penetrating point and serrated gravel grousers, and you can see how aggressive these spades will be at grabbing the bottom of any river, lake, or seabed. The kit includes (4) FFP Anchor Spades, and Stainless Steel Mounting Hardware. Made in the USA and comes with the Fish Fighter™ 100% Money-Back Guarantee.
