Keep in mind that when you are out there looking at buying something new to add to your mining arsenal, that the merchants and manufactures are mining the miners. All of us are susceptible of being intoxicated with the dream of finding gold and buying equipment we may or may not need. Those that are good at marketing and sales know how to press the many buttons that motivate us into buying, with the strike it rich greed button being the easiest of all to press.
Perhaps, think of it this way, when I was a teenager a friend and I were out fishing. This man shows up and casts his line into the water and then told us kids to stay away from his fishing pole because it cost him $600.00 and he paid $250.00 for the reel. My friend and I both caught our limits with our $10.00 fishing poles, reels included in the price. We did not see the man with the highest priced equipment catch one fish or even get a bite. So, in other words, the more money one spends does not necessarily guarantee someone the most success. Just make sure your catching enough gold to justify buying something to speed up the process of getting more gold.
Now, I understand the joy and wonderful feeling of buying a new prospecting toy. I also know what happens when the ether wears off and reality sets in, especially when the new toy does not live up to full expectations. Keep in mind that when you watch a demo of a product, that the product may be demoed in a controlled and ideal environment. When the product is taken into the field for use where things can change from location to location, unforeseen situations may occur, making the product less efficient compared to the demo. Now, to keep things as fair as possible, operator error is often the cause of poor results. So, never badmouth a product without making sure that it is not you, but the equipment that is malfunctioning. All in all, most equipment runs in the 90% range and it is rare, if not impossible to find something that is a 100% perfect and sure a lemon every now and then finds its way into the hands of the consumer. Almost all reputable companies will repair or replace what you bought if this should happen, just make sure you keep all of your receipts.
Having started prospecting in 1974, it is amazing to see all of the new concepts that have been introduced into mining these days. Every time the price of gold goes up more and more new items hit the market, along with self proclaimed gold gurus/experts. There seems to be no shortage of research types that can sit in the comfort of their homes and write "how to books" on gold mining. Sure some of them drive out into the field and get some really good photos to put into their book or article. Don't get me wrong, I actually enjoy reading the material most of them put out there for it is fascinating for me to see how many times the wheel can be reinvented, for that is entertainment at its best, in my opinion.
So, let the miner beware, do your research, spend your time and money wisely, and most of all, have as much fun as humanely possible hunting your golden dreams.
