well heres an opinion and some logic from a beginner, I just got into this whole hobby and decided i didn't want to start with a radio shack special, whats the point if you think your going to do this then you might as well do it right and start off with something decent.
Now i looked around on this forum and read tons of posts of how this is better than that and all the hooey, obviously there are more factors involved than just picking something, what you plan on doing with it for one, and your locations come into play also, i wanted something adjustable with some versatility in the future and i ended up with a whites xlt, now for a beginner i could see how all the fancy settings and stuff could be overwhelming but after perusing the manual that comes with it decided not to mess with it and use preset stuff until i became familiar with the entire hobby and the detecting equipment, now yes there will be those guys that break out some new stuff run around for 10 minutes , find nothing and go right into screwing around with stuff, the key here i think for a beginner is patience and learning technique and what not to do from more experienced people.
I have only been out with this thing for a total of 4 hours and i allready have lil list of things i need, ive started asking others what they are using , digging equip etc.
Ive made up my mind to practice at a beach that is well picked over just for practice until i get good at using the equipment because heres the bottom line.
I have several very promising sites in mind and do not want to out there tomorrow and waste my invitation and find nothing even thought theres a lot of stuff there. again heres where the patience comes in.
To me this isnt about digging up the biggest treasure there is, its about being outdoors and the thrill of the chase kinda thing.
so far ive dug up a dozen or so pull tabs, a crap load of foil gumwrappers, and then i got one huge signal a foot and half deep that i was sure was something that gets your heart pumping it turned out to be a real old sparkplug. now im sure someone collects these things but i found myself asking how the hell it got there, how long its been there and what did it come from.
I think the 2 best pieces of advice you could possible give would be
1 get aquainted with someone thats been doing it for a while for some expert instruction
2 Have some patience and learn your equipment - dont rush in to be indiana jones.
after all i dont think i would have found that sparkplug with the radio shack deal and it could have just as easily been a gold coin. I would also like to point out that this beach is checked by several others on a regular basis so they either missed it with thier equipment or decided not to dig because of the depth

which is it? i dont belive the spark plug with steel, tungsten and brass construction could have given any other signal display or audible other than DIG THIS UP.
oh and on a funny note, i attached the park plug to my lawnmower wire and pulled it it sparked
so added a nother question to my list "why would someone throw out a perfectly good spark plug
