Profoto’s new B10 battery flash is now in stock, priced from $1595.
You can order now from Adorama.
There is also a special offer on the Profoto A1 shoe-mount flash: get a free spare battery with every flash unit purchased (which means you get two free batteries if you buy a Duo kit).
The free battery offer expires at the end of the year — on 31 December 2018.
