and either one will find coins. In fact, there are dozens of detectors on the market that will detect coins. The whole secret of successful detecting is to sweep your coil over the target in the first place. And as someone who has been detecting for over 35 years, that is the ongoing challenge. The questions you asked in this last post are exactly the questions you should be asking. Unfortunately, you are the only one who can answer them. Each of us have our own style of hunting. And each of us have our own preferences of features and functionality. Only you can decide what detector is too heavy. Whether you want yours to operate on 4 batteries or 8. Whether you want or need a pinpointer. And whether your detector should be primarily digital or analog. Fortunately (or unfortunately in some of our opinions) the question of analog vs digital TID has been answered by product availability. Off the top of my head, I can only think of one currently manufactured detector (CZ-3D) that utilizes an analog meter. I still have a White's XLPro. And as I have said many times, I think it offers the best discrimination of any detector I've ever used. But due to component restrictions, analog meters are nearly a thing of the past. In my opinion, weight is not the issue when swinging a detector for long periods of time. I have a physical impairment that makes the detector's balance more important to me. I'd love to be able to utilize the dual analyzation (ferrous and conductive) of the Explorer. And it really don't weigh much, compared to detectors a generation ago. But the Explorer's balance is simply not conducive to my health. Similarly, the Sovereign is not any heavier than my Advantage. But I am no longer able to hover the coil of the Sovereign (the Sovereign wiggle) over a target for proper TID. Some of the "new generation" detectors are very lightweight and well balanced. But I have a personal preference to not use a detector whose coil cable does not screw into the housing. Maybe those that simply plug in are OK for some. But I prefer to have the cable securely connected to the housing. I could go on and on about the differences of many detectors. But all the reasons I would list are simply my opinion, based on my hunting style. Yours may be different.
I do like the fact that the X-Terra only requires half as many batteries. Does that mean I can hunt twice as long for the same amount of money? I don't think so. A new set of 8 batteries on the MXT seems to last longer than a set of 4 on the X-Terra. But not twice as long. There is a "factory" rechargeable pack available on White's detectors. There is not one currently available on the X-Terra. But you can use "off the shelf" rechargeable AA batteries. Since the battery pack of the MXT is directly under the armcup, it does not have an adverse effect on the balance of the detector. Weight, yes. Balance, no. Both detectors have easy to read LCD's. The Visual display of the MXT offers numbers from -95 to +95. There are also block icons along he bottom of the screen, providing a "confidence factor" for a specific target. It also offers a label which indicates the suspected target. The X-Terra offers 28 notches, each representing two digits. It's display registers from -8 to +48. It also provides the interface for establishing and adjusting the X-Terra settings. The MXT offers variable discrimination. Variable discrimination means that, when you set the discrimination knob, everything at that level and below is rejected. The X-Terra offers notch discrimination. Notch discrimination allows me to accept or reject any notch or combination of notches. Although the MXT has variable discrimination, it also offers a pre-set pull tab rejection by trigger. The X-Terra does not have a separate trigger for pull tab rejection. But the X-70 offers three separate Patterns where you could program one to be reject the notches representing pull tabs. Both offer pinpoint capability. The MXT is a trigger and the X-Terra is a touch pad. Both detectors provide depth of target analysis. Both detectors have multiple modes for different types of detecting. The X-Terra offers Iron Mask discrimination in it's Prospecting mode. The MXT offers a self adjusting threshold in it's Prospecting mode. The MXT offers "on the fly" ground phase readings in Prospecting mode. You can obtain ground phase readings with the X-Terra. But it does not offer them "on the fly". Both models offer tracking for ground mineralization. The MXT can be "locked" into a GB setting. The X-Terra can be set automatically, set manually or locked in any GB setting you chose. The MXT has a Salt position and the X-Terra 70 has a Beach mode. The MXT has a Gain control. The X-70 has Sensitivity control. The X-70 has Noise cancel channels. The MXT does not. The MXT offers single-tone coin and jewelry mode and dual-tone relic mode. The X-70 offers your choice of one, two, three, four or multiple (28 ) tones. Both detectors offer an adjustible threshold tone, as well as silent search capabilities. The MXT operates at 14 kHz and comes stock with a 9.5 inch concentric coil. The MXT 300 comes with a stock 300 mm concentric coil. Also available from Whites is a 4 X 6 inch DD coil, a 6 X 10 inch DD coil, an 8 X 14 inch DD coil, a 6 inch concentric and the 12 inch concentric, similar to the 300 mm that is standard with the MXT 300. Jimmy Sierra and DeTech also offer a variety of aftermarket coils for the MXT. In addition, SunRay makes an electronic inline probe for the MXT. The X-Terra comes with a stock 9-inch concentric coil at 7.5 kHz. However, the X-Terra is also capable of operating at 3 kHz or 18.75 kHz. Available coils include the 6-inch DD at 18.75 kHz, the 6-inch concentric at 7.5 kHz, the 9-inch concentric at 3 kHz, the 9-inch concentric at 18.75 kHz, the 6 X 10 inch elliptical DD at 18.75 kHz, the 10 inch DD at 7.5 kHz and the 10 inch DD at 18.75 kHz. No inline probe or aftermarket coils are available for the X-Terra. Both come with a standard 2-year warranty. Whites is transferrable and Minelab is not. Pricewise, they're pretty close!
As I said, I've used both detectors a lot. And they are both good detectors. I still swing an MXT on occassion. But the past two years I've spent most of my time learning and using the X-Terra. Among the most important features and functionality (to me) are the ergonomic balance, the 3 available operating frequencies, number of available audio tones, noise cancel channels, ability to see where I am setting my GB (I like to run a bit positive), notch discrimination and touch pad interface.
