The tec-oriented Xstream is currently one of only two regs approved by the U.S. Navy for cold-water use (the Mares Abyss Navy II was the first regulator approved for cold-water use under the new standards). In ANSTI testing, the MX100 performed very good at recreational depth and good to the depth limits of the test. A single control knob adjusts breathing effort, reducing weight and maintenance costs while preserving high performance air delivery. This simulates the potential demand at maximum recreational depth for a diver at an extremely heavy work rate, or loosely simulates two divers buddy breathing at a somewhat aggressive rate. The simulator monitors how much effort is required to breathe, measuring the work of breathing in joules per liter (j/l).

and many others. I have been taking photos of our Underwater world in Europe, Africa, South America, North America and Asia and I want to share those images and experiences with others. Scuba Diving may receive financial compensation for products purchased through this site. The regulator proved capable on the ANSTI machine, where it was rated very good at recreational depth and good to test limits. Otherwise the two versions appeared identical to us (in ANSTI machine testing they recorded the same intermediate static pressures down to /10 of a psi). Zeagles new flagship regulator leverages the companys heritage (F8 is a nod to the long-running Flathead regulator series), but with a different look and feel oriented as much toward comfort as performance. Divers evaluated each regulator in 13 specific performance areas, assigning scores from 5 (excellent) to 1 (poor), and recording their observations and comments about factors that determine the comfort and performance of the reg while they were actually being used. Intermediate pressure (psi/bar): 130-142/9.0-9.8. Find out how they stacked up in this year's regulator review. This provides increased resistance to freezing in cold water and less dry mouth.

But it was in the water that the Cyklon really shined, proving to be one of the test divers favorites, tying the top ergonomic scores across the board and making it to multiple divers top-three lists. The Venture is good for blocking free-flows although having the markings MIN and MAX on the top of the second stage would make them more visible. The Compacts latest version maintains the trim profile of the second stage but pairs it with an environmentally sealed MC9- SC (for sealed chamber) first stage rated for cold-water use. It also made its way onto more divers top-three- favorites lists than any other reg in the test. My goal is to provide photographs that allow the viewer to get into the image to live and experience the moment vicariously through images which highlight the beauty and fragility of our environment. Two opposing high pressure ports allow the first stage to be positioned either up or down. Inspect it carefully before every use, clean it thoroughly after diving, and have it serviced at intervals the manufacturer recommends. The Prestige was the only reg in our test with no dive/predive switch, but like all modern regs, it uses the Venturi effect to reduce the effort needed to keep the diaphragm open when inhaling. Classic downstream valve comes with a VIVA switch to control free flows. Always be sure to give clean, fresh water time to wash away any salt that has accumulated before it can cause corrosion or other damage to sensitive parts such as valves and diaphragms. The Mares 15X is designed as a compact, reliable regulatory for the recreational diver. Reversible hose attachment allows you to easily adjust hose routing for tech diving configurations.
