The Jackall Master Crank 47mr is a high-performance squarebill crankbait designed for precision in high-pressure fishing environments. Its design focuses on immediate action and stability, making it a versatile tool for Australian anglers targeting species like Bass, Perch, and Trout in diverse conditions. The MR is particularly effective for slow crawling in shallow water, using its buoyancy to rise over snags.
Features:
- Length: 47 mm (1.9 inches)
- Weight: 6.5 g (0.2 oz)
- Type: Floating
- Diving Depth: 1.8 m (approx. 6 feet)
- Hooks: Front #8 and Rear #8
Performance and Design Features:
The 47MR model stands out for its engineering, particularly its ability to navigate complex structures without losing its swimming line.
- Out Metal System (O.M.S): Features weights placed outside the body for an ultra-low centre of gravity. This allows for an instant start-up immediately upon hitting the water, giving cautious fish less time to inspect the lure.
- Circuit-Board Lip: Built with a 0.8 mm thick, durable base lip designed to withstand repeated contact with hard cover like rocks and timber.
- Refined Tight-Pitch Action: Unlike aggressive wobblers, the Master Crank delivers a controlled, tight action to entice selective fish in heavily fished areas.
- Deflection Capability: The squarebill design allows it to "feel" along structure and deflect smoothly rather than kicking out violently, keeping the lure in the strike zone longer.
While the Jackall Master Crank 47MR and Jackall Chubby 38 share high-quality Japanese engineering, they serve different roles in an Australian tackle box. The Master Crank is a larger, specialized squarebill for heavy cover, while the Chubby is a versatile, ultra-finesse staple.

Key Differences:
1. Structure and Deflection
- Master Crank 47MR: Features a square circuit-board lip designed to "bump and run" off heavy timber and rocks. Its Out Metal System (O.M.S) keeps the lure stable, allowing it to deflect and immediately recover its swimming line.
- Chubby 38: Uses a standard rounded bib. While it can be "stabbed and darted" among structure, it is more prone to snagging in thick timber compared to the Master Crank's specialized squarebill design.
2. Casting and Gear
- Master Crank 47MR: At 6.5 g, it is significantly easier to cast on baitcasting gear or standard spin tackle, especially in windy conditions.
- Chubby 38: Weighing only 4.2 g, it is strictly a light-finesse lure. It performs best on light spinning rods with thin braided or fluorocarbon lines to maximize its depth and action.
3. Target Species and Application
- Master Crank 47MR: Ideal for Australian Bass and larger Golden Perch holding deep in snags where a larger profile and better snag resistance are required.
- Chubby 38: A legendary multi-species catcher. Its smaller profile makes it the go-to for Bream, Trout, and Estuary Perch in more open water or over weed beds.
