[size=small]By now you may have gotten a sense that a detector is a detector is a detector. Each has its own unique performance suite and it's devotees. There is always someone to tell you they got a golden pinhead at three feet deep with THEIR pet detector and others to tell you why the color of the detector makes more difference as anything else.
But reality depends on YOU and I'll keep it simple:
How well you know your instrument and it's capacity, the conditions extant where you are operating it at any given time and what actually rests there waiting to be found will determine your success. Not some magic bullet and not because someone says they did this or that, here or there.
So what about the Silver uMax? Excellent, excellent. Good choice, even more so if you can get one for good money. But, consider these, too. Try to find a Silver Sabre uMax (it has a pinpoint button that WORKS). Or a Bandido uMax. Or an Eldorado uMax (Both offer manual GB). Any of these are on the used market for similar money, they hold their value exceedingly well and offer equal or better performance to the Silver.
I love the uMax platform. They are in many ways the epitome of simple, capable detectors. You can swing them all day and with a little knob twiddling they are as good at TID as any machine out there. I carry one with me EVERYWHERE - a Vaquero, these days. But they are all the same and I've had a sample of each that I just mentioned.
Finally, if you intend to hunt in trash as part of your hunt regime, get what ever small sniper coil fits the detctor you choose. Make that a must and make it happen.[/size]
