Using SDC 2300 Or GPZ 7000 Or Both?

Using SDC 2300 or GPZ 7000 or both?  

14 members have voted

  1. 1. Do you primarily use (more than 95% of the time):

    • A GPZ 7000.
    • An SDC 2300.
    • Both an SDC and a GPZ.
    • This poll isn't fair because it doesn't include the GPX series!

Recommended Posts

This poll is designed to see who is currently using either the Minelab SDC or GPZ detectors with a component of identifying anyone who actively uses both.  (I hypothesize there may be a selection bias in this forum in favor of more detectorists who use the GPZ even though sales of the SDC are much higher.)

Okay, it’s time to reveal some bias in creating this post/poll.  Both a GPZ and an SDC have somehow come into my possession.  I’ve used the 7000, but the 2300 remains unused in it’s box. 

I’m curious to hear from anyone that’s had experience using both. Even more so, I’m wondering if anyone has kept both. To the point, are there any convincing (notice not justifiable) reasons to keep both?  Certainly, the easy answer is to use both and see. Different folks like different strokes. However, since the 2300 is still sitting pretty in box, if it’s redundant or secondary to the 7000, perhaps selling it unused is best.  

Looking back in the forum, I found Steve’s detector poll from several years ago. The two most commonly owned detectors were both of these mentioned here. I didn’t see discussion exposing how many people owned both. But, I believe it said many people had more than one PI. With the time that has passed since that poll, results might be different now.  For instance, I hypothesize that with enough time a given hobbyist would settle in on or the other. Perhaps not. Thoughts?

Depends on the terrain in your area.  In the brush and forest, Its easier to use 2300.  Love my Z but i find i only use it most in the desert, although i have identified some spots in the woods to use it.  2300 was my first “good” detector and I have found my best and most gold with it.  I have thought of going with the coiltek coils and dropping the Z but only based on what I have read I currently don’t think it is the route for me.  Today I’m heading out with all 3.  Nox, SDC and Z and after dinking around will pick the best to use.  I have been in garbage lately so the Nox has helped me cherry pick.

The SDC will hit smaller gold than the GPZ and handles some hot rocks better that the GPZ struggles with. If you have larger deeper gold and lots of smaller gold then having both may be worth your while. If you prefer to concentrate on larger, deeper gold and only have so much time to devote to detecting, then a GPZ only may be the way to go. Some places however only have very small gold and so the SDC only may be the better choice. It all just depends on the person and situation, there is no right or wrong answer. Accessory coils are available that blur the line between the two models even further.

Do you need a heavy salmon rod or a fly fishing rod or both? Do you need a little car or an off-road truck or both? Do you need a shotgun or rifle or both?

The question is not what other people need, it’s what do you need? Only your own situation and circumstances plus how much money you want to have invested in detectors can determine that.

I had to pick 3, as when Gold Detecting my split is something along the lines of

GPZ - 50%

GPX - 25%

SDC - 15%

Gold Kruzer - 10%

Thanks for your replies. It’s probably a really common question for which detector is “best”.  An epiphany I’m having right now is that maybe one of the challenges in prospecting is learning what exactly are your needs.  Here’s a theory that I might abandon with time.

When your ignorance quotient is high, your needs quotient is low. Then as your ignorance begins to decrease (from learning), your needs grow. And, finally, when your ignorance seems to be at its lowest, then your needs decrease, again.  It might even be a cycle. Right now I may be in the second phase, so that makes me both curious and needy.

You got that righ! :laugh:

The way most detectorists with experience look at it is that detectors are tools in a toolbox. I’ve had up to a dozen detectors at a time, each for very specific uses. I really worked hard on narrowing that down, but anything less than four really crimps my style. It’s like asking “what is best, the pliers, the screwdriver, the box knife, or the hammer?” It does depend on the job at hand, and whether you want to invest in Craftsman tools or Snap-On. If you do multiple types of detecting and are serious about it, it is hard to settle on just one detector.

      Now that Coils are being made for the GPZ with more and more coils becoming available it's time the discussion came up as to what size coils for the GPZ people would really like to own. 
      What sizes of coil would you like to be swinging?

      Have a video on Audio Smoothing up on the Minelab YouTube channel for those interested.
      Hope this helps
      Prior thread in subject
    • By Steve Herschbach
      The Minelab GPZ 7000 audio Smoothing function was directly derived from the Stabilizer control used on the GPX series. From JP at http://www.detectorprospector.com/forum/topic/715-gold-i-found-in-victoria-with-the-gpz/?p=6424
      "On the subject of Audio Smoothing: Off on the GPZ = 20 on the GPX 5000, Low equals 15 and High equals 10."
      JP at the link referenced obviously prefers Smoothing to be left off. Some people are experimenting with higher audio smoothing settings combined with either hotter Gold Mode settings or higher Sensitivity settings or both. I think this is a good thing so do not go thinking it is "wrong". There is no right or wrong per se, it is all about what works for each prospector and their personal tolerance for noise or the lack thereof. Experimentation is good.
      I thought it would be informative to copy what the GPZ manual (page 66) has to say about the Stabilizer control. Warning: the GPX Stabilizer control is backwards. The highest setting if 20 is the off position. Lower numbers increase smoothing. So the GPZ at off is same as GPX at 20 (off). Note that the GPZ High setting is the same as the GPX default setting of 10. The default for the GPZ 7000 is Low Smoothing which is the equivalent of a setting of 15 on the GPX.
      One final note. RX Gain as referred to on the GPX is the same as the Sensitivity control on the GPX.
      From the GPX manual:
       I guess I should say that my preferences tend to follow JPs - I run with audio Smoothing off under nearly all circumstances. But I wanted to make this post to create a thread on the subject as it is very clear people are having success with other ways of thinking and again, I like out of box thinking. Lunks settings at http://www.detectorprospector.com/forum/topic/830-lunks-zed-settings/ are at the other end of the spectrum. I also liked Jason's observation on the subject at http://www.detectorprospector.com/forum/topic/827-minelab-video-gpz-7000-ground-type/?p=8276

      Hey guys, 
      I hate being the guy asking for help on the forum. But, I'm really struggling and hope some of you with more experience on the GPZ might be able to share some insight.
      So, here's the scenario. I have what I think is an old equipment pad I've been working. I've nicknamed it my "trash patch" since it is just hammered with trash, probably why it doesn't appear to have be detected much even though close by areas have been beat to death. I found my first nugget in there with my GPZ at about 8", The problem, so much trash I couldn't even keep a single target under the 14" coil. I went back this week and spent 2 1/2 days (sun up to sun down) with my GB2 cleaning about a 2500sf area of trash. I can't begin to know how many targets were removed, but I can tell you my legs are so sore from that many squats I can barely walk today. Once I got the area clean, I was super excited to get back over it with the GPZ and see what I could find.
      And, here's where we get to the help part. This entire pad has basically been built with about 3" of crushed hotrock. I thought getting the trash out was the biggest issue, but it wasn't. I can't figure out setting on the GPZ to get through the top layer. Either it just wobbles and whines all over the place, or you choke the settings down so hard it won't pick up anything. I can't find a working medium. Short of racking and shoveling 3" of rock off this area, which moves way outside the bounderies of enjoyable hobbie for me, I'm not sure what to do.
      Anyone have some detector settings I might try, or other ideas would be greatly appreciated.
      Attached are 8 little micro nuggets I pulled off the surface cleaning trash with the GB2. Everything I have got more than 2"s below the rock layer has been larger.
      Thx, Beau

      Well, my Son did it and turned up with a SDC in exchange for my 5000 for Easter. Went off to try the SDC, left him with Z to compare with 5000 and new age coils, he was fairly impressed with performance of 5000 with the Elite 14" but in using the Z to compare he is now spoilt and talking Z Z Z Z only. Suspect the 5000 is history, regardless that the new age coils have increased the performance of the 5000, the stability of the Z has swung him.
      The SDC, it is super stable and a small piece magnet, good fun and will complement the Z. It is the small coil gold detector for those pieces around boulders the Z just can`t get at, plus for those shallow pieces that recovering is time consuming for the Z.
