Aayan, welcome to the forum and the hobby. Perhaps what the dealer meant when he tried to "blame you", was not to "blame you" for supposed damage. But rather perhaps he was saying you're operating it wrong. Because if you have never used a metal detector before, perhaps you are not operating it right.
Example: I knew a guy who sent a Whites XLT back to the manufacturer 3 different times "for repairs". And each time, they sent it back saying it works fine. Yet when he turned it on and tried to use it, the "disappearing signals" phenomenon kept happening. So he'd send it back again "for repairs". Finally Whites suggested he was using it wrong (ie.: "Blamed him"). The guy was FIT TO BE TIED , because he felt like they were insinuating that he was a dummy, incapable of reading the instructions with enough common sense to use it right. He had read the instruction manual 3x, and was confident he was using it right. But still: "disappearing signals".
FINALLY he figured out his problem: Whenever he'd get a signal, he would slow down to "hear it better". But what he didn't realize was that the XLT is a fast motion machine (when in disc.), so when he'd slow down, deeper signals would "disappear". So as you can see, he ate humble pie seeing as how it was an operator error.
I even asked him "I thought you read the instructions 3x. Didn't you see that it said 'motion required' ?". He said that ... yes ... he'd read that. But that he thought they were referring to left/right swing as you walk/progress through the field. And he'd thought "that's a silly instruction. HOW ELSE do they expect anyone to ever get any md'ing done UNLESS they are swinging the coil as they walk. Doh!"
So do you see how NO AMOUNT of printed instructions can convey some things to a person who's never used a metal detector ? Another example is the guy who puts a coin on his living room floor to try it out. Utterly oblivious to the fact that his floor has metal nails in the wood. Or how about the guy who keeps getting signals all over, and sent the machine back for "repairs". Only to realize later than he was wearing steel-toed boots ? The examples are endless.
So maybe you just misunderstood the dealer ?
