inon models

i'm leaning to inon strobes for a d70 in a nexus housing. most users on this site us the 220s. inons site says the 180s are for digital systems. other then the gn what are the differences, recomendations? :?:

The D180 is slave only. No sync cord connector. Get the Z220.

I 've seen in Inon introduce D optical converter that can screw in sync socket

and connect with fiber optic to D180

Yes. I forgot about that. You can operate the D180 that way. The Z220 has twice the power and more power adjustments. The D180 has an auto mode and it's own sensor for TTL like control. The Z220 is the one to get.
