    Minelab X-Terra 705 User Guide

    Minelab X-Terra 705 Instruction Manual, 4.8 MB pdf file, 58 pages
  2. Since we have a wide range of experienced people from all over the world here, I was curious about after the fact thoughts about a relatively old detector - the Minelab X-Terra 70 or newer X-Terra 705. In my experience the coin discrimination modes on the X-Terra 705 rated as “very good” whereas the threshold based all metal prospecting mode is “top notch”. It was interesting to watch at Ganes Creek, Alaska the shift in the latter years. For a long time it was White’s MXT ruled supreme. In the last few years though the X-Terra models came on strong. The main reasons cited were: 1. Light weight 2.9 lb design 2. Superb ferrous discrimination 3. The ability to compensate for interference from nearby detectors (an MXT Achilles Heel) The main reason I bring this up is the recent price decrease to $499 (from $699) made me replace the Fisher Gold Bug Pro ($649) on my short list of Steve’s Picks as a recommended entry level “do it all” detector also suitable for finding gold nuggets. The X-Terra 705 is far more than just a nugget detector, with all the features of detectors that literally cost nearly twice as much. The X-Terra series is rather unique in that you can change the detector frequency by using different specially tuned coils (3 kHz, 7.5 kHz, and 18.75 kHz) It is the nugget prospecting part I am most curious about, having never really employed the X-Terra as a prospecting detector myself outside of field testing. Does it work at all for gold in Australia or does the mineralization slay it? Any other commentary from people in Oz, the U.S. and elsewhere - likes, dislikes - all welcome. What is it best at and where does it fail? I will link to this as a feedback thread later, assuming you all have some responses. Thanks! Here is an old video of a Kevin Hoagland with the X-Terra 70. The 705 is identical as regards the Prospecting Mode so this is a good introduction for those unfamiliar with the machine.
  3. Hi Guys. i bought my exterra 705 this year sorely for prospecting gold nuggets in Zimbabwe. Can anyone help me with the best prospecting settings. I have ventured around where some other people previously found gold but found none so im begining to wonder if the exterra 705 was a good choice or maybe its the settings that i am not getting right. Thank you
  4. Was looking at detector prices lately and noticed the Xterra 705 has really dropped in price for new. Kind of makes me want to go around with it again. Also noticed MarsMD offers multiple frequency coils for it now too, which is a big plus. What to do? what to do? HH Mike

    Xterra 705 Help

    One year ago My husband and I decided to try our hand at metal detecting.We were total newbies with a steep learning curve. We purchased a used Xterra 705 for our starting machine. We downloaded and printed Randy Horton’s Xterra guide and have read it many times. It is a valuable tool for any Xterra owner. We spent the last year educating ourselves on the basics of metal detecting and getting to know our machine. We are feeling pretty confident about the Xterra except for one issue. I am looking for advice on any errors we are committing or if we possibly have something wrong with our detector. We have contacted minelab, but they never got back to us about our issue. So here goes... We are having an issue with TID numbers with in ground silver. We have several old silver coins we use for testing. They air test perfectly per published Xterra TID charts. When we place a coin (dime, quarter or half dollar, doesn’t matter) in a dug plug and cover, the coins register as ferrous (-8, -6 or -4) every time regardless of the coil we have installed. We have the stock 9” 7.5 kHz and the 6” 18.75 kHz Double D coils. We cannot get silver to register as anything but ferrous in the ground. The depth does not matter. We usually run in all metal or discrim 1 on occasion. We go through a set up each time we arrive at a place to detect that includes noise canceling, threshold, sensitivity and manual ground balance, although we usually detect in auto ground balance. We use 99 tones and silver in the ground has a ferrous “thunking” sound to go along with the TID numbers. We have reset to factory setting several times in the hope of solving this issue to no avail. We are out of ideas and possibly need service. Thank you for reading this far. Any advice or suggestions are welcome and appreciated.
  6. Tuesday evening after work i went to the beach again , even though it was a bit cooler and misty i thought maybe there would be something to be had. I got to the beach at around the same time as the last time at 7.15pm and used my Terra , i took the Nox with me in case the lower beach looked suitable to detect . But it didn't , using the Terra is easier on my beaches on the dry tops. I searched the same beach as last time plus another East and by 10.30 i was almost finished when a couple with a torch appeared and were looking for something . They said the Girl had lost a Silver ring , they seearched one area but i thought after looking that they must have lost it slightly further away . And i was right , within a few minutes i had found it . So thats 19 i have had this year , though i dont have a picture of it . My total finds for this search were 2 Junk rings , a junk ear ring , the Silver ring (returned) and £30.69p and also 2 Pencil sharpeners ! My next search will be with the Nox further West on Thursday morning for low tide . Time to find Gold , if its there . I know fresh coinage might be boring to some but to me its what pays for my machines and thankfully it does. It will be a sad time when it all finally goes cashless , finding coins will be very nostalgic .
  7. I am going out on my first detecting trip I think I'll be using an xterra 705. The area I am interested in is south western idaho generlly around silver city the war eagle mine and a few other spots up there> I still have alot to do in terms of research and permission. I t looks promising , rugged and well who knows? Does anyone know if this is what you would call a mineralized soil area? I may drive on over to the Jordan valley area of oregon as well. any knowledge on this location? Thanks in advance.

  9. An acquaintance has asked if I'd help him find some shotguns he buried several years ago. They are wrapped in oilcloths, sealed in PVC pipes (~3 in = 7.5 cm diameter) and buried about 20 inches (half meter) deep according to him. He says he can show me the approximate location within about 10 m. If all this is accurate it seems like an easy task.... Then again, he also said someone in his family (without him being present) tried to find them with a detector and couldn't. That could be due to a lot of reasons as I'm sure you are already thinking, but my concern is that they may be buried more deeply than he remembers. Which of the following would be your first choice? 1) TDI/SPP with 12 in round mono and 16 V battery pack. 2) X-Terra 705 w/15 in Coiltek 3kHz. 3) Gold Bug Pro (19 kHz) w/15 in Nel Attack. 4) F75 black (13 kHz) w/11x7 in^2 coil operating in cache process. Assuming he has the time and patience I'm going to have all four with me to do a comparison, but I'd like to start with the one that gives me the best chance. Your advice is appreciated.
  10. I've never used an aftermarket coil on my 705. There are some out now in dual frequency which is interesting.Any one use aftermarket coils and any issues. Like or not?

  12. Is one of these any better than the other for nugget hunting or are they about the same? How do they stack up compared to the GMT? Any input appreciated as always. Thanks
  13. Are these almost identical machines? Just wondering, a friend of mine has one that might be for sale. He indicates they are almost identical, but why? The 70 was discontinued in 2007. All thoughts and replies are welcome.
  14. I'm considering buying (yet) another coil for my ML X-terra 705 -- 15 inch DD operating at 3kHz. Often Minelab and Coiltek offer complementary (different size/frequency/winding) coils, but in some cases, as what I'm considering, they offer coils that appear to be quite similar. Given that the Coiltek costs about 50% more, I'm wondering if I should apply the "you get what you pay for" standard advice or save $100 for a future coil purchase.
  15. I've wondered for years about how the F19 would compare to the Minelab 705 with the high frequency coil? Love to read anything on this topic. Thanks.
  16. I had been running my threshold setting at 7 to get the slight hum in my phones and it finally dawned on me this is not an optimum setting for picking up deeper fainter signals since a setting closer to 0 should be best. Having always ran the detector volume control in the upper ranges and using the headphones to control the audio level, I decided to switch it around by setting the headphones to max and using the detectors volume control to set the overall audio level. This made a huge difference, now I can get that same slight hum with a threshold setting of 2. Subjectively there seems to be much less modulation on the deeper targets where now coins in the 10"+ range are much louder hits. I'm also running the detector volume control at 4 to 5 to get the same audio volume I was getting before with it set in the mid 20's. Tom OK so I decided to do some air tests to see what difference there is in audio modulation and on coin size targets there is a difference in audio the last few inches. First number is a full audio report distance (or as close as my ears perceive it), second number is the distance target lost. The difference between is the amount of audio modulation where the target volume decreases to the point the signal is lost. The first column is with the headphone volume at max and threshold audible at 1 setting (0 is silent), second column is detector volume at max with threshold at 7 (6 silent) Headphones max......................-... Detector max dime............. .............9" /10" ...- ..7" / 10" Buff nickel......9-1/2" / 10-1/2" ...-.. 8" / 10-1/2" IH penney..........10" / 10-1/2"....-....9" / 10-1/2" As we see there is no difference in detection distance between the 2 settings but a more modulated audio response with the detector volume at max. I also tried the dime with the detector volume at max with a 0 threshold setting and the results were a full volume report to 6" with a max detectable distance of 9", for a 1" loss. Because of this it is apparent that ML has designed the threshold level to follow the volume setting (7 equals 1) which would allow max sensitivity when the detector is used without headphones in cases where a high volume setting is needed to overcome ambient noise. The loss of response on the dime indicating a negative threshold setting because at this volume setting 6 is actually zero. Since these were coin sized targets and not tiny nuggets the difference could be even bigger when nugget hunting.
  17. This is primarily a coin and jewelry hunting topic, I think. Getting more experience with different detectors, I'm wondering if I'm seeing a common (but hopefully not guaranteed) issue. What I'm referring to is called 'wrap-around' and I'm sure it has other names. Basically the low end of the induction balance (IB) ID scale is low conductivity iron and high end is pure silver. But sometimes with iron you get a high ID, usually in conjunction with the low ID. I've had this happen on three detectors but don't remember it on a 4th. The three are: White's DFX-300 w/ 950 concentric coil (least experience), Teknetics Gamma 6000 w/ egg-shaped conc. coil (intermediate experience), and Minelab X-Terra 705 w/ both 7.5 kHz 8.5" round conc. stock coil and Coiltek 3.0 kHz 6" round DD "Digger". I don't remember this problem with my Gold Bug Pro with any coil. I go into detail here with the 705 because I've used it the most in iron infested sites. The lowest ID on the 705 is -8 and the highest is 48. (All even numbers except 0 in between occur but never odd numbers -- by design.) Iron is anything below 0; high conductive coins (Cu and Ag alloys) are above 35 (usually) with silver dollar being highest US coin at 46. (Don't know what a pure silver round would read, maybe 48, but who drops those?? ) In the US Midwest we mostly have moderately low iron content (at least compared to US West) -- may be exceptions in iron mining areas like Minnesota and Michigan Upper Peninsula. I've seen phase auto at 35 with the 7.5kHz coil and 8 or 9 with 3 kHz "Digger" (don't know why the disparity...). I run max tones (~30 of them?) in "Coin and Jewelry" discriminate and alternate between "all metal" and notching Off below 0 and also notching Off 48. Note: this detector has a prospect mode but that operates quite differently and I haven't used it for hunting coins, although I see that some have. Even with the notching described above I get 46's and even 44's on iron targets. In all metal I can hear the jumping between iron ID's and high conductive ID's, but this can (and does!) happen when you're going over a coin near a nail, for example. The hope was that I could listen to tones and not have to look at the screen, but that doesn't seem to work well for me in the iron infested parks I hunt. I'm sure with more experience (and, yes, I've read Randy Horton's "Understanding the X-Terra" multiple times) I'll get better, but I still find myself, even in max tones, having to look down at the screen way more than I would like. So I guess I have a two part question: 1) is this an inherent problem in all coin hunting and multipurpose IB detectors, and if not, which ones are immune to it? 2) Do you have tricks, besides over-notching, to work around this problem? I've found enough old coins that I don't want to notch out halves (ID=44), because I know, although rare, they are out there. Lastly, I'm not interested in modern coins, although those come with the territory. So far I've found old coins at shallow depths (4 inches or less) and none deeper, although I'm sure they are there. I dig lots of pulltabs (square but mostly ring & beavertails) and don't mind that. There are coins in that zone and I'm willing to put up with the Al in order to find them.
  18. It was just this spring that I noted the price for the Minelab X-Terra 705 had dropped to $600. I thought that was good, but somewhere along the way the price dropped again to $499. As of today I find these internet prices... X-Terra 305 $259 X-Terra 505 $349 X-Terra 705 $499 This makes sense with the new Equinox 600 coming in at $649 and Equinox 800 at $899. The X-Terra 705 can be had standard with a 7.5 kHz 9" round concentric coil for $499 or you can also get it standard with a 18.75 kHz 5.5" x 10" elliptical DD coil for $499. The higher frequency elliptical coil variant is known as the X-Terra 705 Gold. Note that the X-Terra can change frequencies by changing coils so owners of either version can have the other by buying the appropriate coil. I don’t think there is another detector out there that matches the X-Terra 705 for features at $499 and it has an excellent threshold based all metal VLF Prospecting Mode. In particular the X-Terra 705 has every ground balance option possible - Ground Grab, Manual Ground Balance, and Ground Tracking with Tracking Offset. It also has a special Beach Mode that allows it to properly ground balance to wet salt sand conditions. The $500 segment is really heating up!

  19. I have had this detector since last Christmas, as a back up to my GPX5000, Which recently has been hijacked.so now its old faithful. Is the Coiltek 15" 17.75.KLH. Worth my time ? I'm just a prospector looking for that pot of gold. Thanks for looking..HH.
  20. Cors (aftermarket independent coil manufacturer) has made coils which are advertised as operating at all three frequencies. I couldn't find anything regarding this at their website, which either means I'm not good at finding web info or they've discontinued making them (temporarily or permanently). At least one Ebay seller has them -- here's an example ad (they were making them in various configurations): http://www.ebay.com/itm/CORS-Scout-12-5-x8-5-DD-Search-Coil-Minelab-X-Terra-All-Frequencies-/291652981609?hash=item43e7df5369 These cost 1.5 to 2x what you pay for a single frequency Cors coil of the same general design (size and config) but if they really do work at all three frequencies then it's about a factor of 1/2 what you'd pay for three coils. Real time multifrequency detetectors such as the Whites V3I and VX3 and Minelab 3030 give you more options (and don't require a coil change) but at considerably higher initial prices. I already have two 3 kHz DD coils (Coiltek 6 inch and 15 inch, both DD) for my X-Terra 705 plus the stock coin & jewelry 7.5kHz 9 inch concentric. Later this week I'll be receiving an 18.75 kHz 6 inch round DD Minelab coil, but I'll likely be on my way to the Southwest US by then so won't have a chance to try it out until I get back mid-February (weather permitting ). It will be especially enlightening to compare the performance of the two 6 inch DD's because the 'only' thing significantly different is the operating frequency. Personally, changing coils hasn't been an issue for me because I usually am hunting with one purpose (e.g. coins or nuggets) and typically you know which coil you want to use, at least which frequency. Also I often am within close proximity to my vehicle in case I want to do a change. I understand that backpacking your swappable coils is more hassle than just walking over to your vehicle.
  21. People send me emails or PMs asking questions and I now have a new policy whereby I will post and answer the question on the forum, then aim them at the answer on the forum (names left out). The whole point of asking questions on a forum is everyone gets to share the answer, plus other opinions can be sought. That gets lost with email and PM. "Regarding the Racer 2, I know you will point me in the right direction, I am looking for a Racer 2 or the X-Terra 705, will be doing coin and jewelry hunting as some beach hunting (two or three times a year) in dry and wet sand, so which one do you recommend? Or do you think they are about the same?" They are very similar detectors in a lot of ways and having used both I don’t think either has any particular magic ability over the other. Nothing a more casual user would perhaps discern anyway. If you are really into your detectors there are feature differences that may or may not be important to you so look carefully at the feature list of both detectors. For instance, if you are into tones, the Racer 2 has mono tone, two tone, or three tone hunt modes. The 705 has mono tone, dual tone, three tone, four tone, and 28 tone modes. However, on the X-Terra how those tones are laid out is preset and cannot be modified. The Racer 2 lets you shift the ranges on the two tone and three tone modes and even change the pitch of the sounds. So while the Racer 2 has a limit on the number of tones within those limits it has more ability to be customized. I like that. I also like full tones so the 28 tones on the 705 appeals to me. That is the sort of stuff one has to weigh. These are the sorts of things that matter to me and that I look at. People always talk about depth and that is a waste of time discussing in most cases. It varies due to the ground minerals at each location and all VLF detectors worth the name are so close it results in endless debates. It is just hair splitting. Now when it comes to picking out different closely spaced items one from the other the Racer 2 has an edge from being a faster response detector. This can help if picking through dense trash. But again, that is more a feature expert hunters appreciate. The Racer 2 runs at 14 kHz. The 705 can be had stock in 7.5 kHz or 18.75 kHz versions, and customized via coil options to run at 3, 7.5, or 18.75 kHz. This seems impressive but in real life has not been a huge factor with the X-Terra because having to change coils to change frequencies is cumbersome. Still, if chasing small gold nuggets was an issue the 705 at 18.75 kHz might have an edge though the Racer 2 is surprisingly hot for 14 kHz. The bottom line is it is like having me try and choose between two different sets of similar hiking boots for you. They are too close to tell which will fit you better and either way I could be wrong. I can use either detector and be happy. My best advice is scrutinize the feature list and both owner manuals online and see if any feature really pops out at you as being something you care about.

  22. Hey y'all-------this is the link to a bunch of pictures and one video of the coil repair---- It isnt the prettiest job but it will hold up now! We used a piece of a PVC gutter downspout my buddy found while we were prowling thru the hardware store trying to find something that would work and hold glue--(Thanks for the tip on nylon--) Anyway, once we finally found that piece it was pretty simple,,,if you lived in a bigger town you may be able to find standard PVC L-brackets and that would save a few steps! Total cost was about 12.00 usd..... plus the fun we had making it...lolol---- (Grumpy Old Men) Thanks again for all your alls help in this 705 adventure!!!!

  23. Been using both the White TDI Sl and ML Xterra 705 with 5x9 coils here in the California Mother Lode and along the Klamath and Trinity Rivers. Between the two detectors been able to handle the ground conditions. Lots of magnetite. Use the TDI Sl over the serpentine. Heavy thick brush, steep terrain, occasional old cabin and tent sites from 1850 through the Depression Era into 1950's. The smaller coils are a must, just can't sweep the larger coils on the steep brushy slopes. Been looking at the Fisher F19 and F75 which both seem comparable to the Xterra 705. Like the option of searching for coins & relics while detecting for gold when an old camp site is discovered. After reading several of Steve's articles on the Fisher Series and Xterra, here is what I think I have learned: The F19 at 19 kHz and Xterra 705 are very close except the Xterra multi-frequency coils selection ( 3, 7.5 & 18.75 kHz); the only waterproof Xterra coils is the 6"; all Fisher coils are waterproof. Not sure if the F19 displays discrim target id in true all metal mode; the Xterra 705 does not. The F19 is a little pricey compared to the Xterra 705. The F75 at 15 KHz 13 kHz in true all metal mode will indicate discrim target id. The Xterra 705 does not display target Id in the prospecting true all metal mode; requires you to toggle over to Coin/Relic Discrim mode for target id resulting in a loss of detecting depth. The F75 Discrim notching is limited compared to the Xterra 705. The F75 apparently has a history of EMI problems; the Xterra does not. The Xterra with a 18.75 KHZ coil runs a little hot for coins and relics but works. The F75 apparent ability to separate out good targets in trashy areas may be a big plus over the Xterra. The F75 stock coil ( 8x11?) may work in the brush. The current base F75 and Xterra 705 price are the same; the F75 Limited Editions $ 250 plus higher. Often switch from Prospecting mode and use the Discrim notching feature on the Xterra 705 then toggle between the notch and all metal to weed out the iron using target id when in trashy old mining camps. ( Use the Garrett AT Pro in pro mode when strictly coin/relic hunting; great target separation; iron audio; but no true all metal mode for prospecting.) Do not know enough about the F75 Limited Edition Boost/ Cache features to decide if they will be useful. Use the TDI Sl detecting for nuggets under a gram so the Fisher F75 15kHz is not an issue. Really like the F75 feature of displaying discrim target id in the true all metal mode; current pricing on the base F75 with two coils at $599 is hard to pass up. Have drop the F19 from the list. Any opinions and experience with the Fisher F75 compared to the Minelab Xterra 705 are welcomed. Keep in mind on the west coast during the gold rush US coins were in short supply; some military buckles from the war with Mexico were exchanged for trade goods. Let me know what you think and keep Santa out of this; on the wrong list. Good prospecting & detecting To all you devil dogs out there, have a Merry Christmas where ever you may be. Semper Fi
  24. Since I am new to metal detecting and read a lot on the 705 dual pack, I decided to purchase one. I sent an email to Minelab and left a voice message regarding a question over two weeks ago with no reply. If I am in all metal mode , how would this differ from prospecting mode with 0 iron mask? It would be nice if Minelab customer service would respond to questions. I sent a question to White regarding their TRX and received a replay with in two days. I am not sure if this is normal or not.
