not quite. The HOG D1, and the DGX Deep Six regs are copies of the Apeks. The D3 is a huge improvement over it, and the Deep6 is a step change above that. Fit and finish on the Deep6 especially is easily on par with Scubapro/Apeks and the cost at least in this country is about 2/3's of what Apeks is.
I know this has been discussed many times, but it is somewhat difficult to dig out from the previous threads and very relevant here.
Do you consider D3 and/or Deep6 signature significantly improved over current Apeks DST? And what is the most important difference?
I also wonder if you can service a deep6 signature using Apeks service kits.
Apeks is strangely placed into premium market segment in the US while in Europe it is more mid range product. Also pricing in Europe for Apeks is very competitive and service kits are ubiquitous.
