Featuring epoxy-sealed eyes and a powder-coated finish, the Heavy Hitter Custom Baits Underspin boasts multiple upgrades to your standard underspin that set it apart from the competition. Built for versatility and the ability to be fished at any speed, the Heavy Hitter Underspin can stand up at rest on the bottom and is designed for high-speed retrieves without blowing out or rolling over.
Forged with a concave construction in the back of the head pairing perfectly with paddle tail swimbaits, the Heavy Hitter Underspin comes equipped with a screw lock bait keeper for the most secure hold possible and to make sure your bait is swimming right at all times. Armed with a razor-sharp 90-degree Gamakatsu 604 hook, the Heavy Hitter Custom Baits Underspin boasts premium swivels and a weight-indicating stamp underneath the head to eliminate guesswork and ensure proper performance.
The Best Underspin On The MarketOh boy do I have something to say about this one! When I first saw the prototypes I was blown away!! Since getting my hands on them I have secured back to back 2nd place finishes in tournaments and landed over 500 fish on it! Well done Heavy Hitters!!

FANTASTICI’ve used the Heavy Hitter jigs, tungsten & punch skirts, so I figured I would give the underspins a try. Well I was not disappointed, they work great! Love the size configured into the heads. These things are well thought out!

Best under spin aroundCan’t recommend this more! Able to slow roll it on the bottom and keeps a great form without falling over. I also love the hook, sets perfect every time and keeps the fish on into the boat! Can’t get enough of these!

Underspin Perfected!Finally an underspin that was well thought out. Blade placement is just right allowing the bait to make bottom contact without rolling over on its side! Gammy hook, great keeper and a sweet paint job! Well done Heavy Hitter Custom Baits!!!

Can Run On The Bottom!This underspin stays upright when slow rolling the bottom! I did this with many other underspins for years and realized those wire out the bottom type connections just make your swimbait fall right on its side when hitting the bottom. (try it in a pool) These just came out and work perfect for slow bumping the bottom and keeping my swimbait right side up unlike any other!

Best Underpin On The Market!Hey everyone if you're thinking about getting some of the new Heavy Hitters Underpins do it! I had the chance to play with some of the prototypes and finished products and they are the best underpins I have ever thrown! They are the only ones on the market that truly stand up on bottom and still allow that blade to spin. Also packed with a Gamakatsu hook which is razor sharp and keeps those big fish pinned till you get them in the boat. Tight lines y'all and definitely get yourself some of these underpins!
