Great fluid heads are hard to come by and goods ones are pricey. You'd think using one is pretty straight forward. Wrong. It takes finessing to dial in the balance, learn where every function is, and time to perfect the art of starts/stops in a move.
That's why we built in Fluid View on Arc II. You can use Arc II by itself as an alternative to a fluid head. Are you going to be able to pull speedy whip pans? No. But, you'll be able to repeat moves, have controlled motion with eased in starts/stops, and even use manually with the built in joystick.
Go out and get creative. Do long moves, short moves, comped moves—there's no limit to the possibilities.
