Two other brands are Salvo and Scubamax
Some of the Salvo regs I have seen (I don't claim to have seen them all, or even how many models they may sell) are Dive Rite clones. I have also seen where Salvo is located. They don't make regs in that building.
Apeks regs made in house in England.
So...are Aqualung regs also made in house in England given that Apeks is a wholey owned subsidiary of Aqualung?
I am sorry but lots of people hear or believe things that they'd be hard pressed to prove. I think if this thread is to be of any use, people are going to have to produce some kind of evidence (web site showing in-house manufacturing facilties (versus just an assembly plant) that supports a view that Brand A is made somewhere and Brand B is made somewhere else.
The reality is that there are very few companies that actually produce regulators and regulator parts as the over all volume of sales is small and the liability and related quality assurance standards are high. Most of those companies either make their own designs, whihc are often rebranded for other companies to sell, make other designs under license for sale to third parties, or make other companies designs under contract for those companies to sell.
Think about it for a minute. If I started the Larry Scuba Company tomorrow, I am pretty sure I could design, or at least get permission to acquire an existing design under license and make some valuable improvements. But actually producing them on large scale would require require a vast increase in infastructure as well as a whole bunch of production and quality control staff who would not really be needed 40 hours per week, 52 weeks per year for the volume of stuff I'd produce and sell. The end result would be much higher unit costs, even if it rapidly became the most popular reg in the industry. My preference, and the smart way to do it, would be to contract with Tabata, Sherwood, etc to produce the design for me.
If I chose to actually manufacture my own designs it would only be because I was a large company with the resources to invest in very expensive high tech production facilities and was selling a very popular design with large sales volume combined with an inability to find a company that could produce regs to the quality standards I required. If I did that, I'd need to get into the business of producing regs for other companies to keep the production facilties at a capacity high enough to make them economically viable. That would put me in direct competition with companies like Sherwood and Tabata who have been doing it successfully for decdes.
I don't see that happening as Sherwood and Tabata make very high quality stuff and Tabata in paritcular has state of the art production facilities. Why would I want to compete with that when it makes a lot more sense for me to benefit from contracting with them and gaining the advantages of their facilties without the huge overhead and operating costs?
People think that a company choosing to subcontract the actual production is a bad thing and that it in some way makes them less of a company. It's not a bad thing, it is just good business and lets them focus their resources on the design and engineering side rather than having to invest huge somes of money into production facilties.
How many parts of the plane do you think Boeing or Airbus actually make in house?
How much of your, for example, American car made by (insert any car company name here) was actually made by that company? Very little. At best they assemble parts here in the US made by a large number of sub contractors both domestic and offshore. At worst, they assemble "American" cars overseas and off load them on the docks here.
Like it or not it is a global economy and the reality is that those countries that sparked the industrial revolution 150 years ago are moving into a post industrial era and the actual production of goods is shifting and is now spurring economic development in 2nd and 3rd world countries.
