Delta 4000 DD 11" coil

[Krusty]

I am wanting to upgrade my coil to the 11" DD style. Every coil I find says it is a screw on connector. The current coil I have on now is the standard 8" with a push connector. I don't see a place to screw one in....am I missing something? Do I need an adapter? Thanks for the help!

Call one of the sponsors here Bart @ bigboyshobbies....he will know how to get that Teknetics 11" DD push in type coil.

I contacted Teknetics/Fisher directly. They told me my detector was an older model which kind of upset me considering I just bought it 2 months ago. They said they changed from push in connectors to screw in connectors as a marketing decision. Anyways, the part number for a 11"DD coil push in connector type is PN: 11COIL-TEK-B

They sell it directly from the manufacture for 125.00

Just some good info in case somebody else buys a "NEW" detector and gets the older model.

I'm confused,just bought a used Delta 4000 and it's coil connector pushes in but then you have a lock ring that you have to screw on then tighten.

You are describing what is being referred to as the screw-on connector. The push-in connector is a male (pinned) connector (on the coil cable) that pushes into a female receptacle. The screw-on connector is a female connector on the coil cable that pushes onto a male receptacle and is held in place with a locking ring.

Duplicate post.

What's the difference as I'm hearing some say old or new model?Mine only has the large headphone plug also.

I reckon here's the other Delta 4000 coil plug.

Yeah. You have the newest version of the Delta 4000 with the screw on connector and large headphone plug.

My understanding is that First Texas/Teknetics made three versions: The first had the push-in connector with the female coil connector receptacle on the control box and a 1/8" mini-headphone jack. The second version had the screw on coil connector and both a 1/8" mini-headphone jack and the standard 1/4" headphone jack. The third (most recent) version has the screw on connector and just the standard 1/4" headphone jack - which looks like what you have. I guess Teknetics just couldn't make up their mind...making coil ordering for the Delta 4000 a tad complicated, if not confusing.

That is something a person needs to know when maybe buying a dd coil.I might later on down the road,their more than I give for my Delta 4000.Waiting for the weather to warm up so I can get out and see what I can find.One degree wind chill yesterday,snow again tomorrow.

Thanks vFerrari,I was worried when I found out there was a new and older version and the newer version was better on interference,figured I had got the old version reason being it was only $160w/free shipping off Ebay.

If it is working, then you got a great deal, even if it was the older version (which I have). My old Delta 4000 still picks up on things my XP Deus has missed! It is a great grab and go detector as long as the soil conditions are right that I plan to pass down to my son to "keep it in the family" even though I am now using the higher end machines. The 8" concentric coil is a great general purpose coil and I don't think there is much point in getting a larger one of any type since it cannot be ground balanced. If I was going to get an accessory coil, I would look at a smaller DD closed coil such as the 5" Teknetics or the NEL 5" Sharp (much less expensive than the Teknetics) or Snake elliptical for trash separation. Not much point in trying to "go deeper" with this machine by getting a only a slightly larger and expensive DD (or concentric) coil than the 8" concentric coil. The advantage of the smaller "closed" coils is that they can be more easily used in confined areas (such as in scrub brush or around fence lines) and they don't get hung up on vegetation like the open spider coils.

I hear you on the not much use of putting a bigger dd coil on it,I'm cheap,that's why I jumped on this one when it was listed on Ebay,before the 4000 was listed there was a BH Quick Draw Pro for about $10 cheaper, so I said I would sleep on it and maybe purchase it the next morning.Next morning it was gone which in a way worked out better for me because of what everybody's saying that this is the much better MD.

Yeah. If you want to just keep it cheap and simple then just go with the 4000 as-is. You will have plenty of fun with it without having to sink any more money into it for coils.
