How we Test Regulators
Regulators are subjected to some of the most in-depth testing ScubaLab performs.
Our testing focuses on two key elements of performance: measurement of how much effort is required to breathe with a reg at depth and how it compares in more subjective measures such as comfort, dryness of breathing and smooth, quiet gas delivery.
Breathing effort is measured at Dive in Panama City Beach, Florida, using an industry-standard ANSTI breathing simulator. The device measures the amount of effort (“work of breathing”) required to inhale and exhale through the reg at a series of depth and breathing rates. The results can help inform buyers, whether they’re looking for the best performance for the price in a recreational reg, or for a reg capable of supporting them and a buddy well beyond recreational depths.
For ergonomic testing, divers score each reg in 14 areas, including ease of breathing, comfort, dry operation, ease of learning, noise, and bubble interference. We also evaluate whether a reg’s first stage high- and low-pressure port arrangement and features such as rotating turrets allow for more convenient and streamlined arrangement of hoses.

Life Support: Regulators
Hog D1X Sealed Yoke Classic 2.0
Jon WhittleTec-capable regulator system with smooth air delivery.

Scubapro MK11/S270
Jon WhittleCompact reg with smooth air delivery and reduced weight.
Jon WhittleScubapro MK11 1st Stage.
More compact and lightweight than its S560 predecessor, the new S270 second stage is made of fiberglass-reinforced nylon with a polyurethane outer layer. Compact exhaust tees minimize exhalation effort and a dive/predive switch prevents free-flows when the reg is not in use. Available with the air-balanced, environmentally sealed MK11 first stage.

Scubapro MK25 EVO BT/G260 BT
Jon WhittleLightweight and exceptionally durable for those long diving days.
Jon WhittleScubapro Evo BT 1st Stage.
This tec-minded diving system utilizes a durable Black Tech DLC coating on the first and second stages to protect metal surfaces from salt water and corrosion as well as minor scratches. The G260 second stage sports a carbon fiber cover with a reinforced technopolymer case. Internal metal components increase freeze resistance.

Sherwood SR2
Jon WhittleThree Pin Link provides consistent flow at any depth.
Jon WhittleSherwood SR2 1st Stage.
This popular regulator system has been given a visual refresh. Offering the same excellent breathing performance, the SR2’s second stage cover is now available in black, blue, turquoise and magenta. It features a breathing adjustment control, and the reg has two HP ports and a rotating swivel with five LP ports.
MSRP $840 | sherwoodscuba.com
Tusa RS-681
Jon WhittleExhaust assist design helps smooth the breathing cycle.
Jon WhittleTusa RS-681 1st Stage.
The compact, elliptical RS-681 second stage features two sets of exhaust ports, with auxiliary exhausts located next to the mouthpiece to reduce exhalation effort. A ceramic moisture plate prevents dry mouth. The click-spring breathing adjustment allows divers to dial in breathing resistance, and the Venturi control tames free-flows.
