The Hollis 100LX Octo is a pneumatically balanced alternate 2nd stage to match the performance of the Hollis 100LX and 150LX Primaries. Adjustable Venturi switch prevents freeflows on the surface to save gas and embarrassment on the surface and it comes standard with a MiFlex® braided hose and an orthodontic mouthpiece.
The design of the 100LX 2nd stage is reversible so you can have a technician change the orientation of the hose if you need. The chrome plated brass valve inside is pneumatically balanced for a smooth breathe at any depth.
- Pneumatically balanced chromed-plated brass valve results in smooth, easy breathing
- Reversible demand valve, can be converted from right-handed hose configuration to left-handed hose configuration
- Adjustable Dive/Pre-Dive switch: Large Venturi lever has a soft rubber grip, which makes it easy to locate and use
- Chrome Plated Brass Valve
- Ergonomic exhaust channels bubbles away from field of view and reduces exhaust effort
- Improved orthodontic mouthpiece with dual color tabs
- Plastic Cosmetic Ring
- MiFlex® braided hose
- Free Parts for Life
- 2-Year Service Interval with Inspection
Hollis 100LX Octopus - Features
?This feature allows the diver to adjust the inhalation setting from the set level and increase the effort required to open the 2nd stage valve to deliver air. Close.
?The venturi control affects how air flows in the 2nd stage. In it's positive position the flow of gas creates a vacuum against the diapragm, helping to open the valve. In it's negative position it will divert gas back against the diaphragm helping to close the valve. It is basically used to help prevent free flowing. Close.
|Cold Water Rated|
?Cold water has adverse effects on regulators and can cause some to freeze so each regulator combination must be tested during manufacturing for their performance in different water temperatures.
Cold water is defined by EN250 as below 10°C. If a regulator combination cannot meet the performance standards below 10°C then they are only suitable for warm waters.
EN250 / (EN250A >10°C)
To pass the regulator must provide at least 62.5 L/min of air at 50M depth above 10°C. Close.
|Cold & Warm Water|
?Environmentally sealed 1st stages offer greater protection against freezing when diving in cold water (below 10 degrees C)
Scubapro have a new method of cold water proofing their first stages called the eXtended Thermal Insulating System or XTIS which still allows water into the first stage but the internal parts that come into contact with the water are coated to prevent ice from forming. Close.
?Unbalanced regulators are affected by the pressure in the cylinder, becoming slighty harder to breathe from when the pressure starts to drop.
Balanced regulators are not affected by the cylinder pressure or depth.
Over-balanced regulators achieve unprecedented performance by increasing your air supply the deeper you go providing the best breathe for deep divers. Close.
|High Pressure Ports|
?High pressure ports supply the pressure gauge and wireless transmitters for dive computers Close.
|Low Pressure Ports|
?Low pressure ports supply the 2nd stages and inflator hoses Close.
?An Unbalanced second stage is simply a lever operated valve that is opened and closed as the diaphragm is pulled inwards by the vacuum that is created when the diver inhales. An unbalanced second stage is affected by increased pressure at depth, slightly increasing the effort required to open the valve.
A Balanced second stage overcomes the effects of increased pressure by utilising a balancing chamber. This chamber takes some of the work away from the spring mechanism, allowing a smaller spring to be used which results in an easier breathe. As the chamber uses air to balance the valve it maintains the same resistance as the diver descends and ascends, keeping the inhalation effort the same. Close.
?All regulators need to be serviced to keep them in working order as the parts inside them age and wear over time and with use. Most regulators need to be serviced once a year or after 100 dives with normal recreational use to replace parts and re-balance.
Some regulators use more modern materials or mechanisms that allow them to extend the servicing interval that can save you some money in the long run. Close.
|1 Year - 100 Dives|
|Weight in Grams (approx)|
?The weight includes the first stage (DIN fitting), hose and second stage. Close.
