Delta vs Gamma

[Merf]

I recently bought a Delta 4000 and am quite impressed with the results after testing it in my coin garden.
It is as deep as my F70 and my Time Ranger with all three in all metal mode.
Does the Gamma have any advantage over the Delta?

Yes. Gives you manual ground balance, more tones, signal strength according to target depth and all metal mode. Few more but thats all I can think of off the top of my head. Any other ? feel free to ask. I can make you a great deal if interested also.
Thanks,

Gamma also has 2 head phone jacks, 1/8 and 1/4 inch, a ground mineralization read out and the programming platform/signal responses more resembles that of the Omega.

I was lucky and got a Delta with both headphone jacks, 2 all medal modes, and the screw on coil connector.

Thanks Stoopstroop,

I found this comparison chart from Teknetics. http://www.tekneticst2.com/comparison-chart.htm

The Gamma has 4 tones vs 3 tones on the Delta.

The one advantage I can see with the Delta is that it has 3 search modes vs 2 on the Gamma.

The signal strength does change according to target depth on My Delta, It is a later model I think.

Note that I said it is a big step up in versatility. Not necessarily a big step in added depth. Oh, the Gamma and Omega will hunt up some deeper targets at times, especially if in the All Metal mode with a good Threshold audio and a proper Ground Balance. There will be times when they can do better in the Discriminate mode, too, simply because they do provide automated and manual Ground Balance control. You also have the ability to lower the Discriminate level a little farther in the iron accept range (to more of an "all metal accept" setting) that helps if hunting in pea gravel, flattish rocks, or dense mineralized black sand like is found on some of our local large river beaches or some volleyball courts at many parks.

That's good to hear, but it's good to know a couple of things, such as:

1.. What coins are used, planted at what depth, and for how long, and what type of ground they are in?

2.. Which search coil was used (I'll presume just the stock 8"), and what were the settings used?

Then, too, a 'test garden' is usually a best-case set-up and lack good targets at odd angles or with nearby masking targets as we might encounter in the real world, or even more challenging ground conditions. Note, too, that these are just comment and not a critical statement because I, too, use a Delta at times and like the performance.

It is as deep as my F70 and my Time Ranger with all three in all metal mode.

Naturally, any model that provides automated or manual GB will have an 'edge' over most factory preset models. One nice feature about the Delta is that it provides a choice between A1 and A2. There is a bit of difference in detection depth and response as well as the Ground Balance that was preset between these two. In some locations both can be used, but if conditions are a challenge, it does provide the second All Metal mode with a preset GB that ought to let you handle the ground conditions.

Naturally, there can be some differences between the Delta and some other makes and models when used in the Discriminate mode, too, and that's where you would note a difference right away.

Does the Gamma have any advantage over the Delta?

Yes, but your initial statement needs to be questioned a little. You stated:

I recently bought a Delta 4000 ...​

What I, or anyone, might first consider is how recently you bought the Delta, and what you have used before getting the Delta? Also, if you are impressed with the performance so far, what is it you are looking for in a step up to the next Teknetics model?

They both use the same 'S' rod and control housing configuration and standard 8" search coil, so they are both light weight and will have the same 'feel' in handling.

Both of them have the same 8-segment Target ID and the same Notch Discriminate capability.


Okay, now to some differences between the Delta and Gamma:

Discrimination:
The Delta's Discriminate adjustment range has six (6) numeric referenced steps that are tied with the visual Disc. 'segments'. They are:

10.. (Iron segment accepted, and above.) Low enough to accept a lot of iron, but still not quite to an 'all metal accept" point to signal through shallow intense mineralization (as I stated above).

40.. (Iron segment is rejected.) Everything below this reference number (virtually ALL commonly encountered small iron targets) are rejected and it will respond to most small foil and gold jewelry on up.

55.. (Foil segment is rejected.) Rejects most typically-found targets below the US 5

Man,you are just one huge mass of information,I just wish I could use it here in Indianapolis.Thanks.

Thank You much Monte for taking the time to explain the 2 detectors.
I have been using an F70 with the 11" DD coil for the last couple of years.

Am looking forward to learning the Delta. I doubt that I will upgrade to a better Teknetics as the Delta will be my backup.

I hunt field sites mostly and hunt in all metal or very little discrimination.

I like to hunt a site with one detector and then rehunt with another detector.

Thanks again for your time and knowledge.

Monte, have you considered starting a class on metal detecting techniques? Without a doubt I have learned so much about MDing from your posts that I wish I could sit down with you and pick your brain, there is so much that you have experienced and the knowledge you have of the different detectors it just is amazing! Keep up the good work!

Really happy and usually AMAZED at what I learn from Monte here on this forum (some of you others are great too.. in fact, we all can learn something from each other).

I own the Delta and right now it's all I can afford. That being said it is VERY important that I know this machine well. Monte's answer really helps. Thanks!
