I have gold prospected in Arizona 5 years. I am on a budget working on success mining. I have found some equipment definitely worth purchasing. If you want gas money, cut corners to get to the claims. I began homemade equipment in 2008. First just looked at other folks' equipment; copied on my own. Took tape measure to a meeting or an outing & measured parts. I looked for plans on the Net.Posting commentary on free plans is offered. URLs are here too.
