The Apeks Flight is by far the lightest reg ScubaLab has ever reviewed, and it’s a real dynamo when it comes to delivering gas. It turned in excellent work of breathing at all test depths and rates on ScubaLab’s breathing machine. In real-world tests, divers found the Flight to be a smooth, dry breather in all positions. It is recommended for water temperatures above 50 degrees, so the Flight is designed primarily for the traveling diver that demands big-time breathing performance. Click here for more information.
