Eon timer really small1/7/2023 ![]() For example, NDL will change from green to yellow and finally to red as no-deco time decreases. Attention-grabbing audible alerts are accompanied by flashing on-screen prompts, which make good use of the color display. The dive display is similarly simple, but does feature a handful of alternate screens, including gas-mix information and a timer. Its two-button operation is straightforward and intuitive, making menus and settings, in the words of one test diver, “easy to access with little experience.” Log data is visually appealing but very basic. The computer’s display took the top score for visibility at depth, but suffers from glare at the surface, making it difficult to read in full sun. “Terrific display, with excellent use of color to make data stand out,” one test diver commented. Measuring just over an inch wide, the i330R uses an uncluttered layout and bold, colorful characters to maximize visibility while retaining a wrist-friendly size. Huggins and operators Armen Bagdasarian, John-Aaron Bozanic, Tom Carr, Larry Harris, Mike Peterson and Ted Sharshan. Special thanks to Catalina Hyperbaric Chamber director Karl E. Meant to simulate a day of diving, the multistage profiles were: 100 feet/55 minutes a one-hour surface interval 70 feet/45 minutes a two-hour surface interval 80 feet/45 minutes a one-hour surface interval and 60 feet/40 minutes.ĭownload full chamber-test NDL readings for each computer here. To gauge the relative conservatism or liberalism of the computers’ algorithms, they were subjected together to a series of four dive simulations in the University of Southern California Catalina Hyperbaric Chamber. The goal of these tests is to gauge how well each computer performed in providing clear, understandable guidance in those conditions. ScubaLab staff also tested computers in a bench-top compression chamber to observe screen displays, warnings and alarms in conditions not suitable for testing by divers, such as rapid ascents and missed deco stops. Onboard log data, including ease of access.Ease of accessing and usefulness of surface interval data, including no-fly time. ![]() Safety-stop performance, including alerts and timer.Usefulness and ease of accessing alternate dive screen data.Overall quality of dive data display, including selection, layout and presentation of data, with a focus on how clearly it presents critical dive information.Ease of reading screen underwater, including performance of backlight.Ease of reading screen at the surface, including in sun.General ergonomics, such as size and shape, comfort, and effectiveness of buttons, straps.Intuitiveness and ease of operation, including configuring settings.Test dives were conducted at Blue Grotto Dive Resort in Williston, Florida, where divers recorded their scores in written comments about their experiences using each computer. Test divers evaluated computers in nine categories. Our test evaluated two aspects of a computer’s performance: how easy it is to operate and understand before, during and after a dive, and an objective measure of its decompression algorithm relative to other computers in the test.
