Actual T-2 coil size is 10"X6.5"

[Old California]

Howdy T-2 fans,

I took apart a T-2 coil and measured the coil windings, Like most coils the actual detection area is smaller from what we assume to be based from the size of coil. The windings measured 10"X6.5" inches, An inch smaller than the coil housing.

I see this on other coils from different manufactures, So please don't be alarmed if the detection area on the T-2 coil is smaller as described from the manufacture. The outer shell is an 11 coil housing and the extra 1" inch added to the coil housing was necessary, Other wise the coil would have had a stubby heel and toe and not so appealing.

The good news is when detecting out in the trashy areas you'll have peace of mind knowing the coil is actually an inch smaller in length, This may account for part of the reason it gets fantastic separation.

Also, The coil windings are the same size of an 8.5" circular coil. So an 8.5" circular coil is the same as the T-2 10" DD coil, Very close to an 8" concentric coil so both may fare about the same on depth.

Thanks for looking and may the T-2 bring you continuous joy,
Paul (Ca)

Hi Paul,

Because one side of the D is the transmit coil and the other side the receive you can't compare them directly to a concentric. Based on your measurements the transmit coil is approx 10 x 3.5" so a much smaller areas than an a similar size concentric. That said, it does seem to work very well based on the finds posted here.

Makes one wonder what the F-75 will do with concentric coils!

is there anything else in there that would appertain to the name helical coil ,are the windings different under that foam ,is there a booster of any kind again hidden by the foam .or is it just a normal dd coil and the machines doing the biz ,because theres definetly something different about the way it works .and thanks old california for being brave enough to strip one down

well done for the gret picture and information,OC

Thanks for the comments gang,

I'm not a coil expert and like most here on the forum are impressed with the fantastic separation the T2 has, Only DJ would know the answer to the secret of the T-2's speedy recovery speed and lighting speed separation.

Here are a couple of more pics of the innards of the coil, We are so fortunate to have such a machine as the T-2.

Thanks again,

whats that little square thing to the left of the picture ,could that be a booster chip .someone must know

Probably a capacitor.

Paul, can you see how the coil is actually built? When are you going to dismantle it completely? You got us curious now, can you see anything different about it? Thanks

Hello Jerry,

The coil posted is a proto-type T-2 coil, I picked up the coil from Mike and it is put together different from what we are using today.

I'll take it completely apart soon, Too many irons in the fire right now and will try to post more pictures soon.

Thanks and keep us posted with your T-2 now that you have the upgrades, Darn good detector for sure.

HH, Paul

The square thing appears to be some sort of chip or something from the picture but it's only one of the several plastic clips holding the coil windings in place, I'll try to post more pics of the coil later after I take it apart further.

Hope it goes back together o'k.I could'nt stand waiting on another one to arrive if I tore mine up some how.Interesting to get a peek inside though thanks for the info.
