Keene, Royal, Gold Buddy or.......

The unit I use is a recently released 12V puffer made by Whippet Engineering. Including the battery and backpack, it weighs 15 lbs. So far, I've used it mainly for sampling places that people really can't get to with larger, heavier units and have been having success. Lots of Kevlar, carbon fiber, and CNC aluminum are used to achieve that weight, so as you would expect, it's not cheap. However, at the rate I'm going, it will pay for itself by the end of the year.
 

Hey everyone, thanks for info to my question I will try the mods and go from there. I will post any new findings.

Thanks again
 

I've checked out their website for this Whippet, but it says "sold out" and I have not gotten a reply to my email inquiry.
I've been looking at the Thompson 12V puffer as well.
 

I've got 2 Thompsons, great machines for either sampling or moderate production and will attach to a pack frame no problem. I think I paid $550/each, now considering a Keene 12v puffer as more of a fixed location machine(they weigh a lot more) and jair says it moves more dirt than the Thompson......Tough to have it all but I'm trying, good thing the o'l lady has no interest in whats in the sheds out back.
 

I think Hamfist has the best machine out there. Like G-bone, I tried to order a Whippet with no luck. I hope he has not gone out of business as it was an incredible accomplishment to design and bring that thing to market. The talent, time, and investment dollars must have been huge.

Another innovative drywasher is the Mad Mining drywasher, as pointed out by blindpig in a thread just above this one. The Mad Mining web page does not show it for sale, and indicates to me that they are not real serious about selling stuff.

Remember to put any good ideas for powering homebuilts on my thread 12 VDC MOTOR HELP, just above.

Whippet Engineering is still in business. I touch base with the owner every now and then and, last we spoke, which was recently, he had just received a bunch of new tooling and cutting machines so they can build these a lot faster. They are making almost no profit on them right now so they're trying to increase their production efficiency.

They will definitely have more in stock at some point.

Whippet Engineering is alive and well.

We have just completed another unit and it is up for sale on the Shopsite store.

Even with the new production equipment we are adding, building these drywashers is quite labor intensive. The longest "pole" in the tent is fabricating the composite parts. It takes 10 days to layup, post-cure, trim and polyurethane coat the eight parts that go into a Whippet Drywasher.

There are ways to reduce this build time by using pre-preg Kevlar and Carbon Fiber, but right now the cost is prohibitive.

Currently our lead time is about 4 weeks. We try and always have a drywasher in stock, but that is not always possible.

I apologize if you were trying to purchase a drywasher, but were unable to do so.

If you do order a Whippet Drywasher, please mention that you heard about us on Treasurenet and I will include either a Apex Talon pick, or a Battery Charger free with the unit.

Best Regards,

I have a big Keene 151 and sure wish I had this instead :) (same price roughly)
 

Do you have some protection of the electric motor to prevent it from attracting magnetite to it resulting in destructive friction?
 

Keene 140 is great. Light, easy to set up. Get a big duffel bag at the military store and you can put everything inside it. Zip it up and grab the handles and go. They all work well it not the equipment, its the ground that makes the difference.
