The model essentially has two operating modes, Watch/Time and Dive. Given that the Geo4 is a decent size, that’s good. I don’t wear a wristwatch normally but didn’t find myself noticing it in everyday wear, except when I needed the time. My Geo4 was all-black, though it also comes in white and there are five optional coloured straps.
SCREENY WEENY 4.0 MANUAL
I then downloaded the full manual and, of course, hardly needed it. After that, everything was sweetness and light. After two minutes of futile and increasingly annoyed and frantic button pushing, I did a very non-male thing and read the instructions to discover which the right buttons to press actually were. The unit is supplied in a state of hibernation and needs to be woken up by pressing the right buttons. It’s powered by a user-replaceable battery, and there’s a special tool in the box for changing it.Īlso in the box is a clear glass protector film to cover the face of the computer and provide protection against scratches, and a Quick Start guide that I did need to check very early on. The Geo4 is a watch-style dive computer that comes with two different-length straps, so it’ll fit your wrist or around the cuff of your drysuit. I’m not sure that Oceanic will like the comparison, but it is meant as a compliment. In other ways, however, the Geo 4 was a 21st-century version of my first computer, and I found myself using it as though I’d owned it for years. I mention all this because that £313 computer was air only, sampled data at three-minute intervals, was accessed using three fingers that you licked and touched to recessed pins to interrogate, and was a world away in terms of features and usability from the similarly priced Oceanic Geo4 I’ve just been using. Well, I could as soon as I got a buddy who also had a computer. I used my new computer for the first time at Scapa Flow, and very quickly realised that by moving a bit shallower, and then shallower still as the dive progressed, I could extend my dive-time considerably without the mandatory deco required by others still on tables. Using the computer, I could just drop in, keep an eye on my depth and gas and surface safely without having to worry about transfer tables, C codes or anything like that, and especially without worrying about setting my blasted watch. And I forgot to reset the bezel on my diving watch a lot too, so had to add guesswork to the overall calculation. In those conditions it’s tough to know if you’re going to 20m or 30m or, sometimes, stay shallow enough to need only a snorkel, so there was a lot of use of the submersible tables that came with the 88 set. This might sound odd, but my club dived the Farne Islands a lot and the final choice of site was made on the day, based on factors such as where the boat-driver fancied going, where other clubs were diving and how much more chugging around the divers onboard could take before everyone heaved. * CleanUrin is not suitable for consumption and may not be used to falsify drug tests/checks/examinations etc.Like the rest of the club I’d been using the BSAC 88 tables, and while it’s possible to plan a multi-level profile with them, it’s actually quite difficult if you don’t know how deep you’re going or the site you’re going to dive before you leave. The sachets are easy to replace so that your ScreenyWeeny/ScreenUrin set is ready for use again as quickly as possible. The temperature in the thermo-sachet remains constant and natural (33–34☌). Important note: ALL three marked types are completely acceptable for use. All three colours have the same high standard of quality. All sachets contain synthetic urine that is equivalent in all relevant parameters to the urine of a healthy, sober person.
Three different identification marks (red, yellow, green) indicate different values in the urine such as pH and creatinine values, as these depend on diet and vary from day to day. Fits both the ScreenyWeeny and the ScreenUrin set.Very easy to replace, so that nothing stands in the way of continued peeing. The refill pack for the ScreenyWeeny and the ScreenUrin set contains completely synthetic urine, packaged in a practical, sturdy 80 ml refill sachet that can also be reclosed. Suitable for all Screeny Weeny models and the Screen Urine Set!
