Highbanker Sluice Box Guide: 6X24 vs 6X42 and What's Actually in Each Kit (2026)
Both sizes in Prospectors Dream's dedicated Highbanker Sluice Box line share the same core kit -- but the mat count, mat pattern options and one included component differ between them in ways the listings don't spell out side by side. Here's the direct comparison.

What Both Kits Share
The 6X24 and 6X42 Highbanker Sluice Box kits are built on the same foundation, verified from each product's own listing:
• .05"-thick aluminum sluice body
• 6" Highbanker Hopper (16 Ga. aluminum, powder coat finish, 1-1/8" hose connection, dual blast nozzle, wrap-around spray bar)
• 5/16" hopper screen (expanded metal & Miner's Moss) to diffuse water flow
• 18" leg kit
• 2000 GPH 12V pump, 12V battery clips, 5 ft. of 1-1/8" hose
• Mat clamp and hardware for the Dream Mat
• Hand-tool assembly, no soldering or special tools required
For a full walkthrough of how the hopper and pump actually work in the field, see our full 6X42 review (linked in the intro above) -- this guide focuses on where the two sizes actually diverge.
Mat Pattern Choice: Combo vs. Mini
Both sizes let you choose the mat pattern at checkout — Combo or Mini on the 6X24, Micro-Combo or Micro-Mini on the 6X42 (the "Micro" prefix reflects the smaller individual mat cells used in the double-mat 6X42 setup, not a different pattern family). For the full breakdown of what Combo, Mini, Vortex and Dredge mat patterns actually do differently, see our Gold Sluice Box Buying Guide rather than re-deciding it here — the short version is that Combo runs two cell profiles for higher-capacity two-stage recovery, while Mini is tuned as a finishing mat that catches gold right at the front row.
Running Either Kit Off a 12V Battery
Both kits ship with a 2000 GPH 12V pump and battery clips rather than a generator or AC-powered pump. That means neither size strictly requires a generator or wall outlet at your site — a small 12V battery (the kind used for trolling motors or as a jump-starter pack) is enough to run either pump for a session. Worth factoring into your total setup cost if you don't already have a compatible 12V battery on hand.
6X24 vs. 6X42: Real Trade-Offs
✓ Pro
6X24 is Lighter and Cheaper
At $359-$399, it's $60 less than the 6X42 and shorter, making it easier to carry to less accessible sites.
✓ Pro
6X42 Processes More Per Pass
The longer body and Double Dream Mat setup mean more material processed per feed, useful for higher-volume sessions.
✗ Con
6X24's Single Mat is the Bottleneck
One mat means one shot at recovery per pass -- fine for moderate feed rates, but the 6X42's double mat catches more on high-volume material.
✗ Con
6X42 Costs More and Is Less Portable
The extra length and second mat add $60 to the price and make it a two-hands, not one-hand, carry to remote sites.
Which Size Should You Buy?
Pick the 6X24 if you're carrying gear to the site yourself, prospecting solo or as a couple, and don't need to run high-volume unclassified feed sessions. Pick the 6X42 if you're processing material for a group over a full day, want the extra recovery pass from the Double Dream Mat, and don't mind the added weight and $60 premium. Neither has a documented advantage in real customer ratings — both sit at 4.9-5.0 out of 5, just with a much larger sample on the 6X42 (19 reviews vs. 8).
