X-TERRA 705

A Tsunami of Coins

April 04, 2014 09:28pm

A very warm day was expected. Like every day at 12 during my break time, I would take out my X-TERRA 705 for a walk in the fields with the kind permission of the local producers.

However, when I arrived at the car, it was so warm that I told myself that I better have my meal at the edge of the water where its shady and leave my detector in the trunk. But of course I couldn’t resist to do some detecting.

Ok, I had only one hour and 15 minutes to do some detecting, including finishing up my lunch. From one shady area to another, it suddenly occurred to me to go to the direction of the forest. I normally wouldn’t even go there because I knew I would not find anything. Nevertheless, I was thinking that at least I could do some detecting where it is shady.

Three new X-TERRA coils from Coiltek

November 16, 2012 12:01pm

A little over a year ago, Minelab authorized Coiltek Manufacturing to produce the 15-inch All Terrain 7.5 kHz DD coil for the X-TERRA. Since its release, the medium frequency 15-inch X-TERRA coil has been proving its capabilities to coin-shooters and cache hunters across the globe. However, recognizing that there are many other forms of “treasure hunting”, Coiltek continued working with Minelab in an effort to develop additional coils for the X-TERRA lineup. These efforts have paid off in the form of three addition X-TERRA coils. They include a new 15-inch All Terrain Double-D at 3 kHz, a 15-inch All Terrain Double-D at 18.75 kHz and a small 6-inch Double-D at 3 kHz.

X-TERRA... Controlling the search coil

January 04, 2011 10:10am

When it comes to sweep speed, the X-TERRA is a very forgiving detector. You can operate with a relatively quick sweep in wide open areas, and slow down when targets are abundant. But to gain a better understanding of how sweep technique may affect the quantity of our finds, let's first analyze the field of detection for both the X-TERRA Concentric coils and the Double-D coils.

Based on my field analysis, with the center of the coil as the "hot spot", I find the field of detection for a Concentric coil will go "straight down" until you reach approximately 55 - 60% of the maximum depth for a specific target. In other words, if you are capable of detecting a target at maximum of 10 inches, you will find the circular field of detection begins to narrow at the 5.5 to 6 inch depth level.

Hunting by ear... Audio tones on the X-TERRA

December 06, 2010 10:08am

With "old" being a relative term, I hunt for old coins at old sites. The part of the world that I live in wasn't settled until the mid 1850's. So finding coins older than 1900 is considered to be a good hunt. Many of my favorite spots to detect are old homesteads and farm sites. With the houses and out buildings long gone, to the passerby, most of these places look like any other corn field in this part of the Country. Pieces of brick, stone, glass and pottery are some of the things that I look for when wandering across these corn fields. And when I start hearing the low tones produced by nails and other "farm trash", I know I'm getting close to where I want to be...

Notch Discrimination on the X-TERRA - Ever wonder what you're missing? Part 2

October 06, 2010 11:34am

Part One of this blog post described how the X-TERRA categorizes targets, based on their conductive values. In Part Two, learn how to increase your opportunity to detect jewelry and old coins by modifying the preset Patterns.

Now that I've outlined how the ferrous vs. conductive properties are represented by the visual and audio TID, let’s evaluate some targets. If you turn your X-TERRA 70 or 705 to the Coin/Treasure Mode, and set it to hunt in factory preset Pattern 2, you will be rejecting notch segments -8, -6, -4, -2, +2, +4, +6, +14, +16, +18, +20, +22, +24, +26 and +48. You will be accepting notch segments 8, 10, 12, 28, 30, 32, 34, 36, 38, 40, 42, 44 and 46. Those of you who have performed target ID tests with your X-TERRA know that this setting will accept U.S. pennies, nickels, dimes, quarters, half dollars and dollar coins. A Coin hunters dream?

Notch Discrimination on the X-TERRA - Ever wonder what you're missing? Part 1

September 24, 2010 03:31pm

A guide for US coin-shooters
A metal detector does exactly what the name implies. It detects metals. Set to accept everything, you will find nails, foil, pull tabs, jewelry, coins, tokens, relics etc. Anything that is metal. In order to avoid digging those targets you don't want to dig, we implement a feature known as discrimination. Metal detector discrimination is basically the same for all makes and models. Some may do it better than others, but the theory is universal. Simply put, discrimination is the ability to adjust your detector so that it accepts most of the targets you want to dig. And, rejects most of those targets you don't want to dig.

Don't forget Factory Preset!

September 20, 2010 01:50pm

I have heard from some users that have tied themselves into knots when trying to find the best settings for their detector. This can happen because there are some combinations of settings that don’t work well together and there are some lesser used settings that you may have set and then forgotten to check.

In these cases please remember to perform a Factory Preset. This will return your detector to the settings that it contained from the factory.

X-TERRA Coil Range

September 13, 2010 11:02am

Why are there so many coils available for the X-TERRA series of detectors?
Good question.

Currently, there are eight coils available to suit your X-TERRA detectors.
All of them do mostly the same, detect metal but a few of them are ‘specialist’ coils more suited to a few tasks “the Pros” or seasoned hunters indulge in!

While there is absolutely nothing wrong with the “stock 9 concentric” that comes as standard kit with a lot of X-TERRA’s, the option to customize your detector without shelling out buckets of money is offered through what’s termed as VFLEX technology available only on the X-TERRA range.

Are you hearing everything you swing over?

July 26, 2010 10:22am

Are you hearing everything you swing over? You wouldn’t know if you weren’t would you? Do you know that it is not just volume that assures you are hearing signals?

A very strong but simple reminder is that you cannot find what you cannot hear!

One of the most unexploited features of Minelab gold detectors is the tone adjustment.
Proper use of the tone adjustment will allow you to custom tune your detector to your personal hearing. And more importantly, it is simple to do.

Reasons to use a Small Coil

May 24, 2010 10:51am

Small coils have extremely good depth and sensitivity despite what popular belief would tell you. If you regularly search areas that you know contain valuable old coins and lots of iron and rubbish then you owe it to yourself to get a small coil.

Why should I do that? The reason is simple really...
