Our ultra efficient LIGHTNING SENSOR V4 trigger has been especially designed for Daytime, twilight, and night-time lightning capture !

Coupled to the wired remote release port, it will trigger your camera as soon as a lightning is detected.

The LIGHTNING SENSOR V4 is the fastest trigger ever made, with a lagtime of only 1.6 µs !

Unlike other compteting triggers that wait for the bright return stroke to give the trigger order, the LIGHTNING SENSOR V4 responds as soon as the first stepped leader appears !

Ultra sensitive, the sensor is able to detect, as an example, an invisible intercloud lightning, and that, even in broad daylight !

It has a "PF" function which, once activated, significantly decreases your camera's lagtime.

PF function is offered as a manually switching because is it the ONLY SINGLE WAY to really decrease your camera's lagtime before a lightning appears (unlike an automatic activation which would be totally innefficient since activated after the lightning detection)

The whole device is dust and rain splashes waterproof (IP56 Standard).

The LIGHTNING SENSOR V4 mounts onto your camera's flash shoe (ISO518 Standard) and connects to your camera via the supplied release cable.

Power supply is done with a standard 9V Duracel alkaline battery (supplied) and consumption is very weak (Battery life of several months).

100% made in France, with a solid, conscientious design, the LIGHTNING SENSOR V4 is compatible with all cameras having a wired remote release port (Canon, Nikon, Pentax, Sony, Leica, Fuji, etc), as well as ultra high speed movie cameras (via BNC cable, by request).
