Canned pineapples??? Coming from Hawaii, having walked in the pineapple fields and worked on tugboats hauling barges full of pineapples; I just couldn't let that analogy slide... I know pineapples, after all
Scubapro indeed makes very fine, outstanding regulators. I've used them, as far back as the mid-1970's, and always liked them. But
"Deep Down You Want The Best" is a great
marketing slogan only, not an accurate statement of relative quality, especially these days... and I find it a really an interesting slogan for Scubapro to use since
Mares set depth records with their MR-22 Abyss a few years ago, and a frequent poster has stated that he's had the old Mares standard, the MR-12, to 500 fsw.... fairly "Deep Down" by any standard I'd say
Mares has not tried to "emmulate" Scubapro to my knowledge; why would they want to? They have a fine product that uses a different design approach to achieve the same end, and this differentiates them from other manufacturers.
As far as history of the two, I'm sort of "fuzzy" on that (I started diving in the mid-70's, I used Scubapro and Aqualung back then). I believe Scubapro as a company is around 40 years old (1960's?). On Mares' website they state they are approaching 60 years (but were they Dacor before?? I honestly don't remember/know).
So, hype and marketing aside, it pays to look a little
deeper (sorry, just can't get past the Scubapro slogan

) when looking at regulators and brand names in general.
Cheers!
