I received the Seculine Twinlink T2D Wireless Trigger and Receiver recently and thought I'd give and overview and a range test to help anyone else who is looking at these. So far, the results are pretty awesome!
First of all, the build quality is pretty decent for both the trigger and receiver. It seems to be made of a decently hard plastic doesn't feel like it'll fall apart anytime soon. The transmitters are well packed in a box and do not seem like they would get easily crushed or damaged in shipping. Everything seems great on them so far! My opinion for this set... If you don't have enough to get PW's or Skyports, go for it! They're a great buy ($150 for a trigger and receiver)!
Now for the proof of the test...
from 5 - 30ft. - 3 fires on each distance - No misfires.
from 40 - 110ft. - 3 fires at each distance - No misfires.
from 120 - 182ft. (as far as I could go before falling down a hill lol) - 3 fires at each distance - no misfires.
For distance (tested only outside so far), I definitely rate the seculine triggers a 10 for the price (about $150). Unfortunately, the only downside that I've seen yet is that the TTL mode on flashes do not work with these triggers. Fortunately for me, I always shoot manual anyway! Just thought I'd help!
