STELLAR BREATHING PERFORMANCE, OUTSTANDING RELIABILITY
The ultimate go-to air delivery diving regulator system for cold water or technical diving.
The HF25 first stage with an air-balanced piston offers excellent resistance to cold-water conditions, what you get is a regulator system that any hard-core recreational or technical diver can confidently take on any dive, anywhere in the world, and be assured of rock-solid performance and outstanding reliability.
The Benefits of Piston Technology
The task of a first-stage regulator is quite simple: reduce the high-pressure air flowing from the tank to a consistent intermediate pressure for delivery to the second stage. By far the best way to accomplish this necessary step-down process is with a piston-style first stage, and air-balanced piston first stage regulators are the first choice of demanding sport divers and professionals.
An air-balanced piston first stage like the HF25 offers excellent reliability thanks to fewer moving parts and is more responsive for instant delivery of air on demand and extra-high airflow—especially in low tank pressure ranges.
Air-Balanced Flow-Through Piston HF25 First Stage
The HF25 first stage provides superb inhalation sensitivity and instant delivery of air on demand, in all diving environments and all water temperatures. The inner mechanism is fully insulated from the environment, improving cold-water resistance and delaying ice formation.
The opposing HP ports allow the HF25 to be positioned either up or down. The five high-flow LP ports provide higher airflow than standard low-pressure ports and are mounted on a swivel turret to maximize hose routing options.
The HF25 first stage lets you enjoy an ultra-fast breathing response, instant delivery of air on demand, great sensitivity and extra-high airflow -- regardless of how cold the water is. The Extended Thermal Insulating System (ETIS) fully isolates the mechanical elements of the first stage from the cold, increasing its freezing resistance without compromising breathing performance. This makes the HF25 the ultimate do-it-all first stage for all water temperatures.
HS260 Second Stage: Effortless Air Delivery and Outstanding Reliability
A great choice for both recreational and technical diving, A diver-adjustable inhalation effort knob fine-tunes air delivery to suit changing depths, water conditions, and personal tastes, and a Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flows in cold water or when used as an octopus.
The HS260 is air-balanced design second stage. Features metal components (inlet tube, orifice, inhalation control knob and hose connector) for excellent cold-water performance. It also offers a left-right hose attachment option, making it a great choice for tech diving configurations.
Of course, you don't need to dive in cold water or find yourself in extreme diving conditions to fully appreciate the powerful yet easy-breathing attributes of this reg system. But if you're a demanding diver you can rest assured that with every breath you take, the HF25/HS260 will deliver effortless airflow and consistent top-of-the-line performance.
HF25 First Stage:
Air-balanced flow-through piston in a chrome-plated brass body provides constant and effortless airflow unaffected by depth, tank pressure, or breathing rate.
Extended Thermal Insulating System fully isolates the mechanical elements from the cold, increasing freezing resistance without compromising breathing performance.
New spring insulating coating, body insulating bushing, anti-freeze cap, bigger body and cap thread all work in concert with the ETIS to improve cold-water performance.
Anti-freeze protection radically increases breathing reliability when diving in the most extreme water temperatures.
Two opposing high-pressure ports allow the first stage to be positioned either up or down.
Five high-flow low-pressure ports on a swivel turret maximize hose routing options.
External intermediate pressure adjustment enables technicians to fine-tune performance quickly and easily.

HS260 Second Stage:
Nylon fiberglass design casing and diaphragm for the ultimate in breathing sensitivity, regardless of position in the water.
Metal components, including metal air barrel and metal valve inlet tube, increase resistance to freezing when diving in extreme conditions.
Air-balanced valve smoothes out the inhalation effort when diving at varying depths and supply pressures.
High-flow exhaust valve reduces exhalation for better overall breathing comfort.
Diver-adjustable inhalation effort knob fine-tunes air delivery to suit personal tastes.
Venturi-Initiated Vacuum Assist (VIVA) dive/pre-dive switch prevents free flow in cold water or when used as an octopus.
