Drew,
A couple thoughts on your comments concerning why Heinrichs Weikamp may have stopped selling their external i-TTL converter. Their decision may have nothing to do with the lack of reliability you cite. Did HW tell you themselves that “lack of reliability” was the reason they were no longer selling the external converter? Do you have any accurate data on what percentage of the converters are failing electronically?
Or is this “lack of reliability” comment derogatory speculation because your own converter has failed?
It is very possible that HW, as an engineering firm, does not want to continue direct sales to the general public with all the headaches that involoves. And having proved that their product works, prefers to license their technology and patents to other flash manufacturers to sell with the strobes they make. And HW will receive a commission on every sale there companies make.
This is what Sea&Sea has already done. And what Inon, Hartenberger, Subtronic will have to do in order to continue to use the HW solution.
I have used my first and only HW converter on approximately 80 dives already with quite satisfactory results. And Tim, as far as I know is still getting satisfactory use from his.
My only dissatisfaction with the HW converter involves its “packaging” and the fact that you have to slide the clear acrylic tube off, breaking the water seal, every time you need to recharge it. I feel this is not a good long term solution for someone who uses their converter frequently. A waterproof charging cap that allowed you to access the mini-USB plug would have made much more sense.
Repacking the converter I have, and a second one if I can get it, is something I intend to investigate.
