GoldenShark Big Boy Highbanker 12V 25cm

The GoldenShark Big Boy Highbanker 12V sluice box is an ideal solution for hobbyists passionate about gold prospecting and gemstone hunting. Thanks to precision laser cutting and digital bending technology, this highbanker is lightweight, sturdy, and extremely easy to assemble and transport.

Powered by two efficient 12V pumps (each with 1100 GPH output, totaling around 140 l/min), the GoldenShark Big Boy easily processes large volumes of material, regardless of whether you're working near running water or in a place without any natural flow. Its portability makes it perfect for adventures in remote locations, beaches, or even your own backyard.

At the heart of this sluice box is the revolutionary #BigShark mat, uniquely designed by GoldenShark to enhance gemstone and fine gold recovery. This one-of-a-kind mat is available exclusively with GoldenShark products. If you'd prefer a different mat from our range, simply mention your choice in the comments during checkout—we'll customize your sluice accordingly.

Included in the kit:

• Complete sluice box (hopper, lower sluice tray, four adjustable legs, durable PVCU spray bars)
• Exclusive #BigShark gemstone-catching mat (25×60 cm) or another mat of your choice upon request
• Two powerful 12V water pumps (1100 GPH each, total approx. 140 l/min)
• Flexible connection hose 40 mm diameter, 1.5 m length (extendable up to 5 m)

The GoldenShark Big Boy Highbanker weighs only approximately 6 kg and offers an impressive processing capacity of around 3 m³/h. For operation, a 12V battery with a minimum of 40 Ah capacity is recommended (battery not included). Total power consumption is about 6A.

The aluminum construction is designed for outdoor durability. Minor scratches that may occur during manufacturing, packing, or transport are normal and do not affect performance or qualify for returns.

Assembly is intuitive, requiring just a few minutes, allowing you to quickly set up and begin your treasure-hunting adventure!

A Little Theory

A highbanker is a portable sluice box that doesn’t require naturally flowing water. Unlike traditional sluice boxes, which depend on rivers or streams, highbankers operate independently using battery-powered water pumps, making them suitable for virtually any environment.

The innovative #BigShark mat, exclusively developed by GoldenShark, significantly increases your efficiency in capturing gemstones and fine gold particles. It's a one-of-a-kind solution created specifically for hobbyist prospectors, ensuring that your outdoor experience is both enjoyable and rewarding.
