User questions & answers

Question:	How long is the hose? Some people have commented that it is short
Answer:	Water sensors are always on.
Question:	What type of vave is this compatible with
Answer:	No, SimpliSafe uses a different method of wireless communication as other companies. Unfortunately, this means that the SimpliSafe system is not compatible with other brands components.
Question:	Is the 2nd stage adjustable for easier/more resistance in air flow
Answer:	Yes you need Simplisafe. Anytime the water sensor comes into contact with water, the sensor will transmit a wireless signal to the SimpliSafe base station, which will audibly announce the water trigger to you. If you are subscribed to our alarm monitoring, you’ll also get a call from our alarm monitoring service to inform you.
Question:	My wife has a small face/mouth. Is the second stage light and how is the mouthpiece for small mouths? Thanks
Answer:	Smart Alerts will be sent to your phone if you are connected to our Interactive Monitoring Plan.

Product description

The XS Octopus has a body of the 2nd stage of traditional dimensions, made of technopolymers and a downstream delivery system with side valve (adjustable), simple and very reliable. An injection duct that channels a flow of pilot air towards the nozzle enhances its performance. The 2nd stage is equipped with a flow diverter that acts on the Venturi effect, with a dive/pre-dive function. Moved to the (-) position, it works as a pre-dive, for entering in the water and for the initial phases of the dive, while moving it to the (+) position allows the regulator to develop maximum performance. Constantly updated over the years, is a regulator that has many admirers in the world for its simplicity and robustness, which translate into practice in ease and low maintenance costs. The performance is high and suitable for any type of diving. The XS Octopus is designed and manufactured in Italy by Cressi, an Italian brand pioneer in scuba diving, snorkeling and swimming equipment since 1946.

User questions & answers

Question:	Can I hook this to t80 compressor
Answer:	No, it does not support Alexa. It can send notification and email to you when the sensor contact water. Need any help, please contact us to [email protected].
Question:	What is the size of the brass tip on the regulator. Or what is it called
Answer:	I have the gateway in my kitchen (middle floor of 4,000 sq ft house) and sensors in both basement and 2nd floor at opposite sides of the house and the connectivity is fine.
Question:	Is this adjustable for input pressure? I see no way to adjust
Answer:	APP can not remotely disable the beep. Since the water-leak detector has sensors on the surface, once it is wet, it will beep, only if there is no water on the sensors, it will stop beeping. Hope we could have your understanding! Need any help, please contact us to [email protected] :)
Question:	can i use this with my scuba tank aluminium 80 3000psi
Answer:	Yes. I believe so. As long as you place it out side the tub wall on the floor where potential water will overflow, it will work. The leak detector 4 sensors at the bottom of the device to alarm you whenever there is a pool of water. Note : There is also a sensor on the top ( two parallel lines) which can detect a drip from the faucet also. Hope that helps.

Ultra-Light, Ultra-Comfortable Regulator

Discover the peace of exploring the water with the SCUBAPRO MK25 EVO/S620 Ti combo, which combines the high-performance MK25 EVO first stage with the S620 Ti second stage to create an all-purpose, all weather regulator system.

The MK25 EVO first stage with an air-balanced piston offers excellent resistance to freezing, and superb inhalation sensitivity. The S620 Ti second stage embraces the best features of SCUBAPRO's renowned S600 in an upgraded, state-of-the-art design.

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 MK25 EVO offers excellent reliability thanks to fewer moving parts, and is more responsive for instant delivery of air on demand and extra-high air flow—especially in low tank pressure ranges.

Air-Balanced Flow-Through Piston MK25 EVO First Stage

The MK25 EVO first stage provides instant delivery of air on demand in all diving environments and all water temperatures. The inner mechanism is insulated from the environment, improving cold-water resistance and delaying ice formation.

The opposing HP ports allow the MK25 EVO 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.

Innovative, Comfortable S620 Ti Second Stage

The S620 Ti provides effortless airflow in a comfortable, lightweight package with an upgraded, state-of-the-art design. The corrosion-free titanium inlet tube inside a rugged reinforced technopolymer case protects against the harsh effects of sea water.

It also features a Hi-Flow mouthpiece with enlarged mouthpiece pipe for improved comfort and airflow, a flow-engineered exhaust tee diverts bubbles out of your line of sight, and easy adjustments via a high-grip inhalation effort control knob and a Venturi-Initiated Vacuum Assist (VIVA) switch.
