Spro Little John 50 1/2oz Cell Mate
The Spro Little John 50 1/2oz Cell Mate is a compact diving crankbait built for anglers who want efficient, castable lures that work shallow cover. Designed in collaboration with B.A.S.S Elite Series angler John Crews, this 50mm crankbait delivers the kind of performance that wins tournaments and fills coolers. At half an ounce, it won't tire your arm on all-day sessions, yet its soft tungsten weight transfer system generates surprisingly long casts for a lure its size—a real advantage when you're working tight spacing or need to reach specific structure without spooking fish.
What sets the Cell Mate apart is its durable computer chip bill, engineered to withstand the punishment of shallow-water fishing without the wear issues of softer plastic designs. The silent weight transfer mechanism keeps noise to a minimum, letting the lure's action and Gamakatsu's razor-sharp treble hooks do the talking. You're getting the same premium hooks trusted by professional anglers, meaning better hooksets and fewer lost fish when a bass commits. The 3–5 foot diving range makes it ideal for shallow flats, grass edges, and rocky shelves where aggressive bass hunt in lower light or tight windows.
The Little John 50 comes in multiple fish-catching colors, so you can match local forage or adjust to water clarity. Whether you're working a farm pond at dawn, grinding a shallow creek, or targeting pre-spawn shallow structure, this lure is built to cast far, dive shallow, and hook up reliably. It's the kind of tool a serious shallow-water hunter reaches for again and again.

Frequently Asked Questions
What's the diving depth of the Little John 50 Cell Mate?
The Cell Mate dives to 3–5 feet, making it a true shallow-running crankbait. That depth range is perfect for flats, grass edges, rock shelves, and other shallow cover where bass hunt.
Will this lure cast far for a small crankbait?
Yes. The soft tungsten weight transfer system is designed specifically to maximize castability. For a 50mm lure at 1/2 oz, you'll get noticeably longer casts than traditional plastic-weighted designs of the same size.
What hooks come on the Spro Little John 50?
The Cell Mate features Gamakatsu #5 round bend treble hooks—the same premium hooks used by tournament and professional anglers. They're sharp out of the box and hold up to repeated casts and hooksets.
Is this crankbait loud or silent?
It's silent. The weight transfer system operates quietly, so the lure relies on its action and profile to attract fish rather than rattle noise. That can be an advantage in clear water or when bass are spooky.
