So, I have gotten pretty good at finding coins, but aside from a matchbox, hotel room keys, a weird button and a flask top (and bottle caps, of course), I am yet to find a single ring with my Ace 250. I found a good spot off the beach where people gather for photos of weddings, proms and the like and it appears to be an area that has not been searched in a long time. Any advice, or do I go about my business with my setting at 4-5 sensitivity and be patient? I have done my practicing on the beach, so this will be one of my first grassy areas. For example, do you guys search in all metal mode or do you hunt specifically. Probably taking a day or two off then back at it. I'm having my Segway shipped to me so I can scout new areas quickly 
Thanks for any insight as always!
