For sale is a barely used B1 Location Kit with original box and all accessories. I used these lights on 2 shoots. Comes with a spare, unused battery.
The kit is the same as here: http://www.bhphotovideo.com/c/product/1049889-REG/profoto_901092_b1_500_air_location.html
with the battery here: http://www.bhphotovideo.com/bnh/controller/home?O=&sku=1009785&gclid=CPSDksvw6cICFYyTfgod2ZAAWA&is=REG&Q=&A=details
Asking $3450 + shipping or local pickup in the New England area. I have feedback under the same name at Fredmiranda, ebay, and audiogon.
Also selling a Canon Air Remote TTL-C, used during the same 2 shoots, for $350. Only available if the Location Kit is sold.
I have not loaded the HSS firmware update yet but it is available. Selling due to a family emergency.
