Location Location Location
I am a newbie to metal detecting and also live on the coast. I sure would love to meet other locals who are interested in getting together at times and MD'ing together. Maybe I'll learn some good tips and I'll finally start finding stuff!
Its all about Location. It doesn't take a hi-dollar machine to find stuff, its all about location and research.
This site is an invaluable place to learn about detecting. Read, Read, Read.
If you are new and just learning. The best thing to do is goto target rich environments, dig everything, and learn your machine.
I would suggest the beach.
Im sure you have heard this a lot, but be very careful digging your holes in public areas and yards.
A lot of people have a negative attitude towards detectorists, because some people destroy lawns, or do not fill their holes properly. Im not trying to preach, just giving advice.
The best target rich areas to learn are the beaches, digging is easy, and they are constantly replenishing themselves with targets.
Also you may want to get a sand scoop, it is nice using these, because you don't have to do a lot of bending over, kneeling, or squatting.
HH and keep on plugging.
