1-1/2" & 2" dredges are a waste of time. The best of the best of the backpacker's is the little Dahlke 2.5. You may be able to shovel faster to a point but you won't completely wear yourself out dredging. Plus you can shovel with one hand, while dredging with the other. Sorry I haven't been on much this month... but we bought a new house and I'm just about done moving in now, I've had my hands full. After 40 years of gold mining, I'm still dredging, still running a trommel, and still having a blast

Now that we're in Arizona, we can legally gold mine in every way, shoot any kind of firearm and have all kinds of fun... lol. Moving into a new house has not been the most fun but I've got a smile on my face again today, now that most of the work has been done. This week I'll be setting up the little trommel here and I already have 15 buckets of high-grade to run.
You can't go wrong with the little 2.5" Dahlke for packing in quick and easy, then a 4" Dahlke 4B these days has come a long way. These 2 dredges, now that I'm over 60, are going to be my next purchases.
16 years ago, I bought a new Dahlke Micro 4B that needed work, but these days, they have it together. I've come a long way since the old Tom Ashworth/ 49erMike forum days of old, but a lot of my old articles are still worth reading. If you're going to buy a Dahlke, then this is some good old info, Bob listened to me before he passed away and made the changes that they still use today. He has had great dredges since long before I bought my first Dahlke and his 7" is still one of my personal favorites over 30 years later
Should you buy a Dahlke Micro 4B
I'm an Arizonan now
