If you want to work a very small area, or if you want to test for very small gold, that Falcon will get the job done. It has a very short learning curve, it's very sensitive, and it will definitely find gold, even underwater.
It's not a big ticket item, but it works very well for what it was designed for, and that's little jobs.
I've found nuggets and pickers with it, but I was looking for small gold, so the larger gold was an unexpected event.
On bedrock that's been running very good gold, the Falcon will sniff out the flakes and specks your other detector will miss as you can get the end of the Falcon's tiny probe (coil head) directly in contact with the gold (in places that will always be inaccessible to larger coils).
It's very slow going, but it will definitely find the gold. It's more of a prospecting tool than a mainline recovery tool.
I've got a picture of gold I found with the Falcon that I'll post. I also worked some small crevices I'd worked with my bigger detector and still found gold I'd missed with it.
If you have the money, I'd buy one and learn how to use it to its specific advantage (small work in tiny areas: bedrock cracks, crevices, small bedrock clean-up, prospecting prospective pay-dirt in dry areas far from water, etc.).
All the best,
Lanny
