Most helpful review for Whites Sierra Super Trac

Sierra super trac
I've had my Sierra Super Trac for two weeks now and I'm pleased with its performance. It's very simple to operate and I've found a handful of coins and sterling silver ring at some local parks in my area. There's no discrimination except for your own eyes and ears. True, it gets a little noisy in the headphones but with tone I.D. You can almost hunt blindfolded. All I can say is so far so good and I'm glad I made the purchase.

Minelab X-Terra 70 : A SUPERB all-rounder!
I purchased the X-Terra 70 at Christmas 2007 after a considerable amount of careful research. I wanted a detector which would give me good results on the beach, in the country and on the Goldfields. It had to be current technology and it needed to break down and fit into a backpack.

The X-Terra 70 is very much a professional machine with a lightweight frame. It even features many of the Professional features found on the top of the line machines in the GPX range. It can be carried in either hand without the need for a harness or support strap and uses AA Batteries: VERY important since you can buy replacements anywhere on the way to the beach or goldfields and carry a spare set without noticeable additional weight. It is also AMAZINGLY low on power consumption so a set of batteries can last me several days of constant use before having to replace them. Specialized batteries for OTHER detectors can weigh a LOT more, possess the dimensions of a house brick, need to be worn on the belt and may cost hundreds of dollars to replace or buy a backup for.

This Detector has default settings in both Coin & Relic Mode and also in Prospecting Mode. But it also has a lot of flexibility for programming personal settings and is the lightest detector I could find with the most features. I just balanced mine on the tip of my finger to confirm it can be done before writing this review.

On the goldfields, it handles the "Hot" mineralized soils better than any of the competition in the same range. It has a range of optional coils allowing considerable flexibility and can (depending on the coil) detect surface gold just a couple of millimeters across and under water (with the 6" waterproof DD HF coil) to larger pieces deeper down using the Elliptical DD HF Coil.

I found the corroded remains of a hair-thin needle fragment buried under ironstone pebbles in a crack in bedrock under 4 inches of water just two days ago using the X-Terra 70 with the optional 6" DD HF coil. This was followed shortly after by a small gold find of several grams located with the Elliptical coil and situated about 4 inches beneath the surface of noisy mineralized soil on the goldfields.

A few weeks ago I found a hoard of pre-decimal coins buried in the mountains and over 200 grams of gold chains & rings along with two hundred dollars worth of coins over a small area of beach which had been scanned previously by other detectorists.

The standard Concentric Medium Frequency coil that the detector ships with is ideal for beach combing and coin/relic hunting. I find the Detector to be easy to use and sensitive enough to handle in any location. In my opinion, this is a benchmark in detectors from Minelab and even a worthy backup or secondary detector to serious Prospectors and a primary detector for Coin & Treasure Hunters since the Target ID display can be used to approximate the target before it is done.

Worth every cent in my opinion. Popular, Reliable and rugged. I expect it will stand up by itself for years to come. Heck, I even use my Minelab X-Terra 70 detector in Pinpoint Mode to scan my walls at home for electrical cables before hanging a picture.

This is a worthwhile purchase for those wanting a high-end beach machine or coin & relic detector ...and is also perfect for those wanting to look for native gold yet are not prepared to outlay the higher costs required for an exclusively dedicated Super Gold Detector (which in turn would probably be unsuitable on the beach). For this reason, I have determined the X-Terra 70 to be the perfect "all-rounder" for all targets.
