I'm sure many highbanker beginners like me would love to have a 12" model and probably with an extension. Bigger looks better, right?
But, I can't find any threads or even single posts about benefits/pitfalls of different sizes of Highbankers.
- Is 8" too small for a healthy energetic person wanting to feed it bucket after bucket all day long?
- Is 12" too big for the occasional hobbyist?
- Is 12" only for a LOT of material?
- Is 10" the nice medium to start with?
Regardless of Pump size and water flow which IS covered in here (obviously a bigger banker needs a bigger pump).
These are all samples of the type of questions about 'size' from the Newbie to highbanking.
I personally have no idea what size to start with or what benefits one has over the other. I'm sure others don't know either.
Any help would be greatly appreciated regarding the Size of Highbanker to use
- 8 inch - you'd be surprised how much dirt you can wash with the added befit of being easy to carry, but yes width and length = volume and with added volume comes added water requirement to move waste product faster, with an 8 inch you'll get away with a 3000 gph or 12000 litres tmc3000 or thornado 1.5inch pump fit that brief.
- 12 inch - Thats a hard one to answer, i'll say this when i use to go out at minimum 3 times per week for 15 odd hours it was no big deal for me to carry a 36kg pump with hoses and a gear to run the 12 inch pioneer series. I could easily pay my rent each with taking from in and around Ballarat vic. Being further away from the Goldfields no living in qld i tend to drive 3 hours to good ground and for me 3 hours in the car slows me down some, i tend to take my 8 inch these days because i know my capabilities and don't want to bust my hump its a personal preference i have two kids (2 and 3 years old) that expert dad to be full of energy when he gets home.
The benefit of the 12s really is volume and if you have low yield pay and a good back you cna make it work and take good gold home and the fact you can buy a 2 inch pump for sub $300 that will put out allot of water very far if needed.
- the 10 inch this is where things get complicated and its sucks, Australia has one of the worst quality pumps on offer for the low to mid range output that's around 14,000 litres and the only pump that hits the mark perfectly is the Honda GXH50 or Honda WX15 (Australian model) these pumps are hands down the best on the market there is no other 4 stroke pump in this size and weight that can put out 7000rpm to produce the flow. it has a price tag to suit at $699 from most honda dealers. the 10 inch is great for people who already ahve access to this pump its a no brainer and you'd be surprised how often you can pick one of these up on ebay for $400 . I've recently been approved as a dealer by BLA Australia who are the distributor for most bilge pumps and will be testing a new bilge that puts out 4000 GPH I believe this will suit the 10 inch as well but wont say unless ive flogged it for a few months myself.
Put simply the right banker will accommodate your average session and what you have access to already, guys who travel on motorbike tend to run the 6 inch recirc, guys with 4WDs and plenty of room tend to lean towards gear that will process more gravel and that's the 12 inch. but thats not always the case as you ahve to balance carried gear beer, food etc etc
a simple guide for standard size Dream mat cell (2 inch cells)
8 inch - min 3000 GPH / 12,000 lt per hour petrol pump
10 inch - min 3700 GPH / 16,000 lt per hour
12 inch - min 3700 GPH / 18,000 lt per hour min for a petrol pump works best but with less pressure resistance 16,500 will run the material well at a loss of cleaning pressure.
There are variants to this rule with classification and gold size but these really are the values that work well. I hope this helps some.

. . but I accidentally left it behind last week. Hopefully it will still be sitting where I left it when I go back to that same spot
I had to use stand-ins this week :awful:
GoldDigga87 said:Dragon man I seen your video and am looking at building the exact same set up as your 12" gold rat but in the smaller 8" version. I've looked at the clay claw from gold hog but they will only sell it with a unit and won't sell them separately..
How did you go about getting your hands on a clay claw?
Hi Reeks.Good thread Jem.
I sit my pickup strainer in a submersed bucket in the creek (usually layed on its side) so it only picks up clean water.
A big snapper lead in the strainer stops the hose from floating the pickup.
