Bowens' Pulsar Radio Trigger System
Work Wirelessly...On Location And In The Studio Page 2
Pulsars operate at 3v so they are a perfect match for sensitive digital cameras that can have their systems fried with sync current that's too hot. They not only worked perfectly with the Canon EOS digital SLRs that I use but also with a borrowed Fujifilm FinePix S1. Unlike infrared flash sync devices that can't shoot through walls or around corners and can occasionally be unreliable, Pulsars use radio frequencies that allow them to function up to 100 meters (333 ft sounds longer), which should be enough for most photographers.
Bowens says you can "expect to enjoy over 200 hours of continuous use from your Pulsar." That may be true if you remember to turn the transmitter/receivers off after you use them. When I forgot to do that, the two AAA batteries were toast when I wanted to use them for my next photo session. AAA batteries are not as readily available as the ubiquitous AAs, but I was able to find four at a nearby 7-Eleven and now make sure to have back-ups.
So waddaya gonna do with these puppies, just toss 'em in your lighting bag? On the contrary, these are precision instruments so I placed them inside one of Norazza's (www.norazza.com) Ape Cases for digital cameras. The case holds two transmitter/receivers with antennas up, as well as having outside pockets for cables, phone plug adapter, and that cord that clamps the receiver to your flash head or light stand. Then I tossed the Ape Case in my lighting bag.
Other than when I forgot to turn
off the Pulsars and wiped out the batteries, they performed flawlessly in all
kinds of mixed environments. They were really put to the test inside a large,
metal-framed factory that was sure to wreck havoc with radio signals, but the
trusty Pulsars never missed a beat. I was able to use them to shoot in large
atriums where I placed a monolight in a loft area but stayed on the ground.
I got wide angle portraits that were well lit because the lights were tucked
out of sight--one story up.
The Bowens Pulsar Radio Trigger frees your creative mind from one last detail: You don't have to worry about flash sync any more. I never want to use cables again.
