Dacor Darwin Wrist Computer?

[ChrisA]

I'm looking for a new computer. Reading the specs on the Dacor Wrist it looks good but I can't seem to find out what algorithm is used inside or how the bottom times it gives you compare to other brands.

I like that it uses AAA batteries. I dive at night frequently (about once a week) so I will use the light and using the light means battery replacement. AAAs make that easy. I might even be able to use rechargables?

I have not been able to find an on-line user manual. If someone could point me at the file (if it exists) that would answer all questions

The Dacor website (divedacor; you put in the www's and the .com) is, shall we say, not particularly useful? OTOH, the algorithm & guts are extremely similar to the Mares M1. If you check out the Mares manual, you won't be too far off of the Dacor.

OTOH, the algorithm & guts are extremely similar to the Mares M1. If you check out the Mares manual, you won't be too far off of the Dacor.

The Mares M1 (exactly the same computer as the Dacor) utilizes an “11-tissue exponential deterministic algorithm, with M values (low bubble) derived from studies by Rogers and Powell (modified Haldane)” according to the Mares website—I think the mention of “M values” would make it (possibly) a Buhlmann algorithm? According to John Francis of ScubaLab, “Albert Buhlmann added to the Haldanean model the idea behind ‘M values’ developed by Robert Workman. These values represent the theoretical amount of overpressure that tissues can tolerate without forming bubbles. Buhlmann also gave more attention to slower tissues.”

Mares also offers a newer M1 RGBM, which utilizes a “Mares-Wienke RGBM algorithm.”
