I am researching better equipment after my last prospecting trip broke 2 shovels. The area where I like to set up my sluice and run is next to a large gravel bar. The issue is the gold is deep (1-2 feet) under gravel varying in size. Getting down there is hard work but it pays off very well. I am wondering if there are any specific types of equipment that you all recommend for digging in gravel. Any info would be appreciated, thanks!
