ROV-500, affectionately referred to as "Squirt", is Outland Technology's smallest ROV to date and comes with a single, waterproof briefcase for the console and power supply.  But don't let Squirt's compact size fool you.  The control system was designed to maximize the power of brushless, DC-flooded thrusters in order to yield a high thrust to weight ratio.  And there you go, a compact design that continues to deliver at Outland's high standards of performance.
