    Computer vs Algorithm

    Hi Michael, Thanks for your interest in Cochran dive computers. There are obvious proprietary issues that come into play when discussing the algorithms in our computers. To put it as simple as possible, our algorithm is designed to give the maximum bottom time, with an aggressive...

    There are also consumers that equate "used by the military" with durability and reliability. As I said before, every diver has their own unique preferences. Fortunately, we have several different manufacturers to choose from to find something that fits our particular requirements...

    Just because the appearance of the dive computer hasn't changed doesn't mean that the function is also the same. It seems to me, given the nature of the sport in which the equipment is being used, that function should take priority over form. And there are divers that already use our computers...

    I assure you that the recreational dive market is not an 'afterthought' to Cochran. In fact, we were designing and building recreational computers before our affiliation with the U.S. Navy began. As for not being a 'very good fit' with recreational diving, that is also not true. Our EMC-16...

    What you dive is your preference...what the Defenders of this country dive is a decision made by people who are familiar not only with the equipment, but it's application to the mission at hand. Part of the training for divers using our computers is how to activate the backlight in a hands-free...

    There was an open competition for designing the first Navy Dive Computer. Cochran was one of the very few manufacturers that even responded, and was the only company to successfully implement the VVAL-18 algorithm. Since then, we have implemented several other Navy specified algorithms and...

    Thank you for your consideration of Cochran computers. Our dive computers have always employed automatic gas switching (in fact, we may have been the first). As for the OLED screen and configurable display, I have no response other than to say that several years ago Cochran Undersea Technology...

    All Cochran dive computers that are air integrated track the workload (breathing rate) as well as the temperature. The user has the option of enabling these environmental factors to affect the decompression calculations. ----------------------------------------------------- Cochran Undersea...

    I inferred that Shearwater computers are one example of the type of computers you were referring to when you said "newer dive computers having exciting, flashy displays." Was I incorrect? I apologize for not catching your inference...it seemed to me that you were taking my post as an...

    You assume that just because I don't dive a Shearwater computer, I am unfamiliar with their algorithm. Quite the opposite, as I have studied many different decompression algorithms through the years. You also seem to presume that I dislike Shearwater displays exclusively, which is also not...

    Unfortunately, I sometimes can't live up to the standar Shearwater computers were not available when I began diving. Before I was even employed by Cochran, I had performed my 'due diligence' on dive computers (and all other pieces of dive equipment) and had determined that the Cochran...

    While I may be an employee of Cochran, I promote their products because I feel they are the best available for divers. Yes, they don't make much of a fashion statement. True, their appearance hasn't changed in a while. But when it comes down to the actual PURPOSE of the dive computer, I...

    The same applies to the EMC-20H (although only a single finger is required). In fact, the EMC-20H will turn on by itself when immersed. --------------------------------- Cochran Undersea Technology & Cochran Military designs, manufactures, and markets state-of-the-art diving computers for...

    Using an electrical interface (shorting contacts) rather than a mechanical interface (pressing buttons) is to prevent any 'accidental' changes to the dive computer's configuration. Depth implies an increase in pressure, and mechanical switches are subject to these forces. Mechanical switches...

    That's not entirely true...I have programmed my EMC-20H with a dive knife, a coin other than a quarter, even a bottle cap. The only thing that the quarter is required for is to remove the cap for battery replacement. -------------------------------------------- Cochran Undersea Technology &...

    Thank you for your interest. The Lifeguard dive computers utilize the same algorithm as the EMC-20H, but with more 'environmental awareness', including repetitive dives, ascent rate violations, and more. There is also the user option to modify the conservatism of the algorithm in the field...

    Actually, I was recommending the dive computer from the perspective of a divemaster (which, after all, was the context of the initial conversation). And since there seems to be some sensitivity to my posts, I will modify my 'style' to hopefully prevent any unpleasant perceptions of "conflict of...
