Digiflavor Siren V2 GTA

[beedee]

I like mine DaveJ, when I first got it I had the coil too close to the airholes and this gave me an initial bad impression of it, but once that was sorted it vapes nicely. Must admit, I prefer the Innokin Ares, because the refilling is sooo easy - but I'm lucky in not getting the leaking that stu1873 is experiencing.

I love these tanks, they’re pretty much all I use now. It’s the first MTL tank I’ve seen that’s made a change to the seemingly standard design of having a single air hole under the coil, to 3 holes running along the length of the coil.

Does anyone know what the supplied coils are?

I think I read somewhere that the supplied coils were 3mm ID, 26 gauge, Kanthal. The coil I used from the pack came out at 1.01 ohms.

I didn't try the ones supplied in the box. But a quickie google came up with:

from linky

I used one of the pre-built coils that comes with the tank – SS316, six and a half wraps, 2.5 mm inner diameter, slightly spaced

and from linky

The Digiflavor comes with 1.0 Ohm pre-built coils, which are 2.5 mm inner diameter, SS316 coils, which are six and a half wraps and slightly spaced

So from those reviews, I assume they are SS, 2.5 mm dia with 6 1/2 wraps.

Those are the specs of the coils I wound for my Sirens. I didn't use the coils supplied in the box. Perhaps that's where you read of those kanthal specs?

This is what I read:

The coils that come with it are 3mm ID 7 wrap 26 gauge Kanthal, and come out to about one ohm. In SS316L, the same build comes out to about 0.5 ohms.

I wonder if it came with two different coils. The one I put in my Siren 2 was definitely 3mm and it came out at 1.01 ohm.

Oh ...

Silly me thought a coupla on-line vaping reviewers might know what they were on about.

Seriously - the ohms you got (1.01) is bang on for that configuration of Kanthal. If that coil was SS it certainly would be much lower.

So I dug out my original packets of bits that came with my 2 Sirens. All 4 coils between the two packets look identical - colour, texture, size and "how bendy" the legs seemed. I measured the coil diameter. They were all an equal snug fit onto a 3 mm drill bit. Pics:
 

I didn't hook 'em up to try measure resistance though. BUT all 4 coils of mine (between 2 Sirens) were 3 mm diameter internal. All 6 1/2 wraps, closely spaced. Which agrees with your comments and clashes with the two on-line reviews I found and quoted.

Maybe those reviewers were sent advanced "kit" which was changed once things went into production? Just guessing is all. But it seems production versions of the Siren include Kanthal coils of about 1.0 ohms.

And that I was wrong about the coils. *sigh*     Oh, well...

DaveJ , it's very odd. I thought maybe the second coil was different so I measured it on my coil jig and that one is 3mm ID too. I was starting to think that maybe there was something wrong with the Siren 2 I received so it is good to know that yours is the same.

I have seen online that some people say a 2.5mm ID coil gives more flavour so maybe it would be something to experiment with.

ETA: My Siren 2 is the 24mm version too.

I've seen a lot of things online ... including what coils these sirens are s'posed to contain in the box. *grin*

Different configurations of coil may alter flavour but I'm not so good at detecting flavour variations myself, so that sort of experimenting would prolly be a little lost on me. What I would observe though, is that the base of the coil deck has wick cutouts of a set size.  Going too small in coil diameter might result in too little wick to properly fill those cutouts. 3 mm obviously works well, 2.5 prolly would too. But, say, 2 mm might be pushing things a bit too far.

ETA: Yeah the 24 ml version - because that's the big capacity one (4 ml). I am not into "TPD" 2 ml tanks.

Perhaps it is best not to go there, DaveJ.
