Probability of a large company acquiring a small CCR manufacturer? Zero. The money is not there and you make yourself a large litigation target. It’s not worth for US lawyers to go after JJ. Scubapro on the other hand…
Probability of a military manufacturer selling civilian units? Zero. The economics and needs don’t make any sense.
You are asking the wrong question.
No not zero. Head Sports/ Mares offered a CCR by acquiring rEvo III. And I read they are doing very well post Head era. In Europe and other regions it is almost the only unit sold to universities/ institutions/ scientists / studios / well funded agencies etc.
Anyway even if it's zero. The question needs to be asked. Are you aware of any big companies offering CCR? There is nothing wrong with this question.
