Dacor use to make some really good stuff from the early 50s' thru about 2000. They were purchased by Head Sports to join a line of products that include Penn tennis stuff, 2 or 3 different names in sking and snowboarding, and now Mares and Dacor in the scuba diving department. Head announced that Dacor would no longer service or make parts for any equipment made before the takeover date. This made many owners of Dacor regulators mad because they were sold with an unconditional "lifetime" warranty which promised to supply both parts and service without a time limit to the original "registered" owner. They even mailed out plastic warranty cards to the owners as proof they received the mail in card. Now the plastic cards and the paperwork that the warranty was written on in the manual is not worth anything. The new stuff Dacor has released has not made any great advances. It is "average" at best and I would rate most of their gear about the same quality as XS , LDl,ScubaMax and Cressi. I would never buy another Dacor product because of their past history and never knowing when they may deceide to discontinue service and parts on their current model lines. (Note : many LDS have dropped the Dacor line due to the problems of getting parts not only for their older merchandise but the current lines as well. They perfer to go with other companies like Atomic, Zeagle, Aeris which are younger and more commited to providing customer service. Mares still makes excellent equipment also but I'm a little worried because they are still owned by Head.)
