Difference Between New 521 Tab and Original

Hi Folks,

I was sent a replacment 521 Tab by these nice people at Coilmaster when my original went faulty but i have noticed that there is a new one been released so was just wondering what is the difference between the original and the new model.

Many thanks

  • Thank you for that, the replacment you sent out to me apears to be the old design but has the spring loaded 510 connector ?
