Well if you look at some of my posts, I do pretty well on beaches. Your machine will work fine on fresh water beaches, not so fine on salt water beaches.
There are three main conditions that have to exist in order for you to find gold.
1 Gold has had to be lost where you are searching
2 You have to get your coil over it and it can't be deeper than your machine can go.
3 You have to make the choice to dig it.
I think it took me a few years to find my first gold ring on land. They can ring up from foil to an overload tone. If it has a broken shank, you can be sure you will get a broken iffy signal. Same with gold chains.
Getting land gold is very hard. If someone lost a ring on land they search for it. Most are probably found. If dropped in water it gets covered by sand instantly. Almost impossible to find.
If gold was super easy to find EVERYONE would be searching for it.
I think I have 19 pieces of gold this year. I haven't added them up. 53 last year. HOWEVER here are the pull tabs, bottle tops and some of the small junk I have found this year. This is NOT including bullets and shot gun shell head stamps and cartridges and other brass:
THAT is a 5 gallon pail. So I get all that and more for maybe 19 pieces of gold. Sure us water hunters make it look easy but it is in fact a chore to find it. I am positive I dig over a thousand pieces of trash for one piece of gold. However being in sand and underwater I can easily dig over a hundred pieces of trash an hour.
Keep searching and don't get discouraged. It takes a LOT of time and effort to find a piece of gold anywhere.
