Thinking about getting a X-terra 705

Well-known member
I have had the heavy weight machines and really loved the depth of them, but due to health reasons I had to go to a lighter machine. Thinking about getting a x-terra 705 but not sure what coil to get. I do a lot of coin/ jewelry hunting hunting in the parks and open schools around here. Once in a while I go to the pacific beach areas. From your experience what should I look for in getting started with a x-terra 705 ?
 
If your ground is very mineralized a DD coil is a must, i have very hot soil and a concentric coil will not work at all. If your soil is mild the the concentric coil is the best. Check you ground balance numbers with you other detectors and if it is 25 or below to a DD coil.
 
Since you already have experience, I would recommend that you download Randy Horton's FREE e-book "Understanding Your Xterra".
It's an easy read in very understandable terms, and it will give you a taste of exactly what a 705 can do.

You will also find several interesting pieces to check out in the FAQFAQ thread pinned at the top of this forum page, including links to a three part blog article that Randy wrote for Minelab on "Which Coil Is Best For Me".
 
Get the gold pack 705...comes with the eliptical hi freq coil...super light...good depth
..great on gold and good on coins..seperates up really well(fine line of detection on the coil).
I think the gold pack is the same price as the 9" med freq coil that is the other way its offered.
If you lean more towards gold the eliptical is the one to get.
 
Look in the classified ,I have one for sale with extra coils

I was talking to a friend of mine and he asked me how the x-terra 705 was on finding bottle caps ?

It takes a bit of practice, but the audio gives 'em away.
 
Old Longhair, could you be more specific ? I'm trying to differentiate between a few bottle caps that I have (rusty and new) and recent clad or silver coins and I don't find it easy. I'm having more success at 18 kHz than at 7.5 but it's still not very convincing. I can identify a bottle cap with relative ease with my Fishers at these same frequencies with the visual ID and audio but I can't say the same of the 705. To me the audio doesn't seem to change much on clad vs bottle caps unless I rotate the coil 45 degrees and swing it on top of the target at an angle. I then get distorted audio or a change of tone to lower conductor or ferrous on occasion but that only seems to work at 18 kHz. I don't have a 3 kHz coil so I can't try it at that frequency.
 
Mike are you getting solid ID numbers on the meter with the bottle caps. Almost all of them I find I can determine by the ID numbers jumping around extreme meaning down real low and then back higher whereas a coin or ring can have some meter numbers change but usually there in the same ballpark, not varying much, indicating a solid target to me.....my T2 is the same way.
Also the audio like longhair says isn't quite solid, its got a small break in it not gving it a full solid tone, kinda like a coin laying near some iron. Try raising your coil a little too, that can help.
I mostly use the hi freq 5X10.
 
Hi Neil and thanks. I'm getting solid high numbers on bottle caps like with most detectors. The difference is that with my F5, as soon as I start lifting the coil up at least 3-4 inches on top of the cap, numbers start going steadily down and vary a lot with of course the tone variations to go with it. With my higher freq detector (F19) this doesn't work as well. With that one I use the heel of the coil on the bottle cap and the same thing happens. I get low numbers going into the ferrous region. With the 705 none of this seem to work very well at least not for me. Numbers stay pretty solid right up to where they vanish altogether. The sound gets garbled once the coil is getting far from the bottle cap but it does the same thing on clad.

I'll try it again, listen very carefully and examine the ID. At one point I'll pick out something for sure. It's just not as obvious as with the other detectors I use.
 
I like my 70. They are almost same machine. I have had about 5 xterras I will probably always have one because I have 9 coils for mine.
 
When over a bottle cap start dragging back until you get to the tip of your coil and it should break up and the ID numbers will jump around. This also works on pull tabs but you then run the risk of missing gold.
 
Good targets tend to sound good, and audio rules. If you can make it sound bad then odds are that it is. But if there's just something about it that attracts you, dig it! Clean clear repeatable tones are usually what you're looking for, but sometimes there's something about the audio that got your attention that bears checking out.
 
Yes I have that coil. It's a great coil. It really likes the coins but it will give different Ids on some coins. I have dug coins in yards that I seemed to have missed previously because the tone is much better with the digger coil. When coin hunting it rarely comes off my detector anymore.

Mike where you compare to fishers my humting experience comes mostly from BBS and FBS machines.
Im guessing youve tried different sweep speeds?
Can you say what it is you like anout the 705 compared to the one fisher detector you mentioned that is good at IDing bottle caps?
Thank you
 
Once you take the advice of the above people, bottlecaps will only seldom cause you problems. I took there advice and it helped.
 
Good info here.Bottlecaps are just part of the hobby,just like junk.Nothing wrong with the xterra for digging bottle caps.i try to avoid them but that sound is just too good Somtimes and I just dig it already knowing it's a bottle cap.
Xterra 705 just has the best audio going in my opinion,and light weight.Good luck

I never had anything but First Texas machines. The 705 intrigued me because of the almost endless discrimination options it has. Being able to change frequencies with the change of a coil is attractive too. I can hunt for gold and jewelry at 18 kHz and put a small low frequency coil in my backpack and hunt for old silver coins in another area. I still feel like a total newbie with the 705 so I can't give an honest opinion on it yet. I just find it difficult to get used to it because it feels worlds apart from the First Texas models.

The 705 runs so quiet and smooth it can give the impression its diengaged from the ground compared to my T2 which is a bit more chirpy I guess you could say...but gives a completely engaged feel...like your hitting every possible target in the ground ....especially comparing the 705s prospecting mode to the T2s all metal mode. The older fisher 1266 I think is alot like the T2 in "ground feel".
The 705 has to be trusted even though its a quiet machine.
ETRAC will talk to you too :)
