Portable Performance — Built for the Field

The FlowCore is one of the best gold prospecting sluice boxes for beginners and seasoned hunters alike — engineered for prospectors who refuse to choose between portability and performance. A smart foldable design and integrated vortex-optimized riffle structure make it one of the most capable compact sluices you can run on any creek or stream.

Specifications

• Full size: 29.5" (L) × 7.9" (W) × 2.2" (H)
• Folded size: 14.8" (L) × 7.9" (W) × 3.5" (H)
• Material: PETG — durability, moisture resistance, and UV stability

Features

• Foldable design — collapses in half for easy pack-in and storage
• Central handle with integrated locking mechanism — keeps the sluice rigid and flat during operation
• Vortex-optimized riffle design — engineered for real gold recovery, not just looks

What's Included

• 10 × M6 × 16mm screws
• 10 × M6 nuts

Assembly Note

Apply silicone sealant along all joining surfaces before tightening screws. This ensures a watertight seal and prevents fine gold loss.

Why PETG? PETG offers the ideal balance of strength, moisture resistance, UV stability, and impact toughness — exactly what a field sluice demands.

Built Different. By Design.

Most gear in this industry is sourced from a catalog, rebranded, and shipped. Not ours. We design it, manufacture it, inspect it, and ship it directly to you — no middlemen, no third-party parts, no compromises. When you find something in the field that needs fixing, it feeds straight back into the next build. That’s why we ask for your feedback — you’re not just a customer, you’re part of our design team. That’s what maker-direct means. That’s what you’re buying.
