Themost durable, portable and affordable underwater trigger. Ever made.

More information

The basic uTrigger system includes everything you need to get started on your remote release project.

How does it work?
On the inside there is a sensor connected to the camera which can detect a triggering signal of the transmitter through any type of housing wall up to 20mm thick (Aluminium, Plexiglass, Stainless steel etc.). It works underwater and above water.

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.

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.

•it is universal which means you don't need to buy a new device when you change your camera or housing
•it can operate for more than 4000 triggers and up to 3000 seconds of bulb time on a single battery
•it features a bulb and lock option for long exposures and to avoid accidental triggers
•it can be supplied with a three stage voltage meter to test the batteries
•it works in manual and autofocus mode

Depending on the thickness of your housing you will find out at which voltage the batteries need to be replaced.
