Gravity and equalization can only get you so far. When you are blending for a 300-foot (90-meter) trimix dive or topping off rebreather cylinders, you need precision and pressure, not just whatever is left in the supply bottle. Gas boosters are the essential tool for technical divers and dive shops who demand full fills without wasting expensive helium or oxygen.
The "whip it across" method of transfilling leaves a lot of gas behind. As soon as your supply tank pressure drops below your target pressure, you are stuck with a partial fill. A quality gas booster pulls that low-pressure gas from the supply cylinder and compresses it into your dive tank, ensuring you get every cubic foot you paid for. This efficiency pays for itself by drastically reducing the amount of "unusable" gas sitting in your bank bottles.
