Thanks guys. It has ego and 510? connection. I use a cover and a knock off mini vivi nova at times.

I really dont want to build coils, though I may try. I lack some feeling in my finger tips and small objects are hard to work with.
Yep, that's an ego/510 connector. Should fit any head with either ego or 510 threads (which is about 99% of them!).
And that coil is a short-post evod/kanger style. (In case it isn't obvious, by "post" I mean the part that sticks out the top).
Edit:
The longer-post styles won't always fit in place of the shorter-post ones; they get jammed in the tube.
Although I also think there can be slight differences in the diameter of the post as well. There are a TON of different replacement coil heads and while most are compatible, some are just a bit off with regards to the top post. I have some heads that will take either long-post or short-post, others where the long-post won't fit.
