DTRO may be small now but their products, with the right campaign, could hit a lot of big, untouched markets. If their products are of the quality they claim then they will be big into the future, especially if they keep acquiring profitable companies.
So far their rebreathers have the potential to hit all of the deep sea research going on due to the oil spill and the research that is going on to find new species. This technology also allows recreational divers to go deeper and experience something new they have yet to see.
Acquiring Elasco and having a contract with Sector 9 to make eco-friendly wheels allows them to hit the alternative "Go Green" movement that continues to sweep across the country.
I personally think that DTRO is only going to go up from here and with the right acquisitions DTRO could become a pretty big company.
