Whats the purpose

Whats the purpose of blowing vapor out of your tank or RBA before taking a hit? I watch a lot of vid’s and every one seems to do this.

I’ve witnessed this as well. What’s the deal?

Some coil builds have a ramp up time.

By blowing vapour through the device first it ensures your coils are at their best firing temp and producing good vapour.



Thank you
I could not figure it out.
