Beautiful pack. The high bid is now at $900, with 3 hours remaining, That is the cheapest I have ever seen for a Topas pack with so little use!
I sold my previous Topas A4 packs for $1,500 each. These packs have a lot of beautiful features and are a joy to use.
They have twin LCD displays of power output, one for each head. Full assymetrical power output to the two heads - like having two sepeerate packs in one. Adjustments are in .1 stop via a push button control.
Settings range from 10 (3200 Ws) to 4.5 (25 Ws), or 12Ws with 2 heads attached. Broncolor calls that a 6.5 stop range on their web site.
Changing pack settings could not be easier - it is very intuitive and simple, with quite a few options. The only problem is that once you use Broncolor equipment you are hooked, and spoiled for less well designed units!
Cheers,
