That is a very good point. I certainly do not have any plans to get rich from gold prospecting. It'd be great if it happened but I really just want to get out and have fun trying to find some gold, any gold, including the tiny pieces. I would consider anything found to be a success. For me, this is a hobby for fun, not a job.
I'm interested in the comparison between the Goldbug II and the Racer Gold. Seems like the Racer has an advantage if it can ID a target while in threshold-all metal mode whereas the GBII cannot(?) I will have to look over the specs and manuals to get a better feel for each. I would also be concerned about being an early adopter of the Racer Gold though. Who is to say a new and improved version isn't right around the corner, such as what happened with the Racer / Racer II? I've also heard speculation as to the new Fisher machine. If that is a hot gold detector, it may be worth waiting for.
Thanks for the helpful comments Steve, appreciate it.
