Yep the perfect Pulsar system - for no reason seems to be acting up.
If one fires the camera, I can get a misfire or even a series of misfires.
Really depressed, I was so pleased with these. Even the one time I forgot to plug in the mini aerial I only got 2 misfires in 530 images.
Now for no reason over the last 3 shoots ( say average 400 images each) I can get 10 to 20 misfires, really makes one look so unprofessional. If one had bought £50 YN's fair enough but at £99 for then TX and £72 for the receiver card I am hacked off to be honest.

Weird thing is, if it fails to fire a couple of times, and I revert to triggering it with the "Test Fire" button on top of the little TX transmitter, it seems to fire and then continues to fire. But if one does not do this, then you can get 4 or 5 misfires.

Initially I thought dirty head-shoe connection, cleaned it but no improvement. Then I thought must be a head-shoe to Transmitter faulty connection, which it could be, as the Test Fire button does seem to work every-time. So the TX can trigger the Monolight in these circumstances, i.e. if you push the Test Fire button on top of the TX transmitter.
If my logic is right that means to me that the transmitter unit is able to send a fire signal to the receiver card, and that is able to fire the Mono-light. So logically is it just a headshoe to transmetter connection issue?

I tried my 430EX II and a friend's 600 EX RT, Never seen a misfire, unless it obviously was a definite 'no line of sight' failure - NB running optically. Therefore I assume the 8 month old 7D is fine. Apart from these 2 New Canon Speedlights, used in this Test, nothing else was put in the 7Ds shoe-head. So I ruled out the 7D as the problem.

On the last shoot the group setting seemed to get messed up. I.e. it seemed to be triggering only when the transmitter was set to 3. But the receiver card was set to any group.
Now this could have been me panicking, when it went down, and pressing the wrong buttons.

Any ideas before I speak to the Manufacturer on Monday.? Much appreciated
I had heard Bowen's had some problems about camera's Orientation stopping it fire with the original Pulsar triggers. But I also heard they had solved that with the new generation TX .

Feeling low as these were real expensive and only triggered the Bowen's kit, and did not not trigger my speed-lights. Joke laid out for then to be sure my studio would be rock solid! Could have had radio triggers for both, for less than half the cost with Yongnuo. YN 622s.
