This is a little off subject, but it is something folks should consider when buying anything.
I purchased a Mine Labs Explorer S from an estate sale. I was told it did not work, and it didn't. The batteries had been left in for who knows how long. Once I disassembled the unit, I made a list of what I needed. I had (and still have) a report with KellyCo, but without part numbers, they couldn't help me. I sent an e-mail to Mine Labs USA. After 10 days, I sent another. Still no answer. I called them, and during normal business hours, the phone was not answered. I was beginning to wonder. So, I sent an e-mail to their home office. That e-mail elicited a response from the ML USA, advising me to send it in for repair. Having all the equipment to work on things of this nature, including surface mounted technology tools, I returned the e-mail again asking for part numbers. No response.
I then decided to call Australia. I was put on hold for nearly 15 minutes, and then hung up on. A second call finally got me to the head of customer service. Lots of apologies, and I did get the part numbers I ask for. I also got two e-mails from the General Manager of the USA operation, and eventually a telephone call from both the US branch, and the folks from Australia. The former once again asking me to send it in for repair, and the latter making sure the USA branch called me back (they didn't, they just e-mailded me).
I finally located the parts (KellyCo didn't have them in stock), and I managed to repair one part. It took me about 3 hours of bench time. It now works as it should, but it took me nearly a month to get the answers I needed.
I also purchased a used Ace 250 from the same estate. The coil was damaged beyond repair. Although out of warranty, I did get a lower cost than I would have had to pay from a dealer directly from Garrett. Funny thing, however. I didn't receive the coil, and I added that comment to an e-mail about a whole new issue. Unexpectedly, I got a phone call from Garrett apologizing for the delay. I could wait, or I could receive a demo 9x12, which I opted for. I have ask several other questions of Garrett, and received replies almost immediately.
I am sure there are other manufacturers with very good service as well. And I'm also sure there are some as bad as Mine Labs was with me. The whole point being, if you're going to spend big bucks (to some, $200 is very big bucks), it pays to buy products which can be serviced, not only at the dealer, but at the manufacturer as well. Since almost everyone has a web site, telephone, and an e-mail address, contact is easy. If you don't get answers in a reasonable length of time, I'd think long and hard about that brand and/or dealer.
