About uTrigger

The uTrigger is universal trigger which means you don’t need to buy a new device when you change your camera or housing. Simply replace the connector and sensor cord and assemble them in your new camera kit.

How does it work?

On the inside of the housing, there is a receiver connected to the camera which can be remotely triggered via a wireless signal from an external trigger.

Signal between the transmitter and the sensor can travel underwater through a maximum of 20 mm of aluminum.

How do I focus?

The uTrigger uses a one stage triggering method which works with manual and autofocus settings.

with the camera in autofocus mode and the focus priority turned on, the camera will start to focus when the button is pressed:

• Once the camera is in focus it will be triggered automatically
• If the camera is in manual focus mode it is triggered when the button is pressed.

Bulb and lock

The uTrigger is equipped with bulb and lock functions which allow the photographer to make long exposures. When not in use the uTrigger can be locked to avoid accidental triggers and using the battery.

Advantages

The uTrigger can be connected at any time during the dive thanks to it’s short range wireless technology. When not connected the uTrigger can be mounted to your BCD via the mounting rope.
