Gamakatsu Under Spin Head Size 4/0 3/8oz

The Gamakatsu Under Spin Head in size 4/0, 3/8 oz combines a swim bait jig head with a small spinning blade to trigger aggressive strikes from bass, pike, and other predators. Built on Gamakatsu's Heavy Cover hook—a 60-degree design with heavy wire and a wide gap—this head delivers solid hooksets and reliable retention when you're throwing bulky swim baits in thick cover. The heavy-gauge hook is also at home on heavy braid or fluorocarbon, so you can target shallow vegetation, timber, and rocky structure without worrying about hook failure.

The streamlined head profile is designed to slip through cover cleanly, while the Gamakatsu Spring Lock keeper holds your swim bait or soft plastic in place—straight and secure—so your presentation doesn't slip or twist during the retrieve. Recessed eyes on the head give the bait a more natural profile and serve as a focal point for fish. The real trigger, though, is the small chrome blade mounted on a quality ball-bearing swivel. Even on dead-slow retrieves, that blade spins freely to mimic the flash and vibration of a wounded baitfish, adding a subtle but effective attraction to your swim bait presentation.

Whether you're working shallow flats, punching grass, or dragging deeper ledges, the Under Spin Head bridges the gap between a traditional jig and a bladed swim bait—giving you the durability and cover-getting geometry of a heavy jig head with the reactionary appeal of a spinner. A solid choice for anglers who want one compact lure to handle multiple situations.

Frequently Asked Questions

What swim baits and soft plastics work best with the Under Spin Head?

The 4/0 size works well with small to medium swim baits and soft plastics. The Spring Lock keeper is designed to hold both types securely in place without deforming them.

Is this jig head suitable for shallow water and heavy cover?

Yes. The streamlined head profile is built to slip through vegetation, timber, and other cover, and the heavy-wire hook and strong construction support the demands of heavy-cover fishing with braid or fluorocarbon.

Will the blade spin on slow retrieves?

Yes. The small chrome blade is mounted on a quality ball-bearing swivel that turns freely even at very slow speeds, so it will generate flash and vibration throughout your retrieve regardless of pace.
