The picture you show is our BHQ11 head. It has a seperate control knob for pan lock, ball tilt drag and ball tilt lock. Three control knobs in all. The head has a 11 pound capacity and it has a quick release with safety. BHQ11 is all aluminum structure is covered by our 10 year warranty.
We do make a BH11 head, but it is only sold on our TRAVERSEB11 tripod and head combination. The BH11 has 2 control knobs, one for pan and one for ball locking . BH11 also has a quick release with safety. This tripod and ball head combination is also covered by our 10 year warranty. Hope this helps!
