Good shoot out. If you already have Aputure lights, the Amaran would win my vote. You can control it and all other Aputure lights with Sidus Link. Quieter fan and solid track record making dependable lights seals the deal.
If it has as accurate a clock as Aputure claims, it might be worth it for the TC alone since the price is the same as Tentacle Sync boxes which also have a drift rate of 1 frame every 24 hours. Then you get all other features. But does it have external volume control? Need that for ifb.
I wouldn't put the Lectro LT/LMB into the same category as the Azden and Wireless Go. It's a pro system that will outperform every other system in the prosumer category by a huge margin. I have a couple sets of the LTs/LRs and they perform nearly as well as SRCs and 411s/smqvs. They're also wideband so cover three blocks.19ms of latency isn't a benefit at all for the Deity Connect. It makes syncing with analog sources like a boom difficult. That should be in a con category.
There are actually quite a few cheap GoPro frame mounts out there that offer many of the features that this has. I have a metal case that allows you to use the bigger external GoPro battery, 1/4 mounts for mics or accessories and a filter thread. It does vignette a little on the widest setting, so I wonder if this one clears completely. The expanded memory is nice, though. That's a first.
