The benefits, from my point of view:
- Sports an ISO hotshoe, on the unit itself. (primary plus)
- 1/4" screw mount on the side of the unit, opposite from the shotshoe mount.
- Compatible with Pocket Wizard PlusII(s)
- Claims of longer range!
- Less expensive: $108 vs $169 per transciever
Don't get me wrong, if I needed extra PW(s), I'll go to my local camera store and pickup more PW(s). However, by all accounts, these Atlus units are quality devices in their own right. The signal compatibility with PW(s) means a less expensive means to expand the flash triggering network.
More on this when it arrives.
