Straight Drives
A bow thruster is an electric motor and impeller in the front of the boat, below the water line, that is installed side-ways in a hole that goes through the boat left to right.
If you turn the motor on one way, it drives the bow to the right. If you turn it on the other way, it drives the bow to the left.
If you put one engine in fwd and one in rvrs, it does the same thing. If you have a huge boat that you need to parallel park, get a bow thruster. Otherwise, learn the boat without. Save the money, maintenance....
I'm surprised that people buy 2 B-III drives - That's 4 Stainless Steel props, on 28/30 foot boats. With a single, it provides excellent maneuverability. On a twin, I can't imagine that it helps much. They are more efficient though.
