If I set the XL Pro to accept nickels, will it accept US gold coins? And apparently, the answer is yes. I've been coin shooting for over 30 years and understand that ground mineralization, trash concentration and "angle" of the target create inconsistencies. I found on my MXT that gold coins vary similarly to what you indicate will happen with the XL Pro. I also found that Indian cents vary from high 30's to the low 70's on the digital meter of my MXT, depending on the metallic content. As such, I expect that a proportional variance will apply to the analog meter on the XL Pro as well. I will add that several of the places that I believe there to be gold coins have low to moderate mineralization as well as minimal "modern" trash. Quite honestly, for a "beep and digger", those types of areas don't require a detector with visual display. But, it is always enjoyable to predict what a specific target is going to be, before you dig it. Thanks for the response. HH
