I have never bought a metal detector because of the warranty. I have plenty of Tesoros and knew when I bought them second hand that they were not covered. I also knew that very few people had problems with them because they are reliable. I did have to replace a cracked coil on a Stingray that could be 25 or 30 years old and paid for it. Other than that I have had problems with 2 coils, the one in this thread and one for the Makro Racer 2. I have 12 detectors from various companies (Teknetics, Fisher, Tesoro, Garrett, Nokta, Makro, XP, and Compass) and multiple coils for all including aftermarket ones, except the Compass Judge 2 and never had a coil failure other than these three, one old and two from the "latest and greatest". I have seen on the various forums that quite a few Makro/Nokta coils have been returned. Rather than replacing a faulty coil, they just say, "Sorry, it is no longer under warranty. Can we sell you a new one?" They do not want to examine it to find out why it failed but then maybe they already know why. I have had other detector companies go out of their way to help me even when the product was out of warranty. And not just metal detector companies! Look at recalls for automobiles, firearms, appliances, etc. If something is faulty they usually have to fix it or make amends. Nokta/Makro won't.

What I did learn here was to watch out for the hype about how great a certain company is in responding to your problems. Also I learned that they are not near as good as others in responding, according to my experien
