Does the TURTLE work with any underwater housing?

Basically only the camera and underwater strobe setup matters. If the underwater housing has any bulkhead to control the strobe or a connector for fiber optic cable it should work properly with the TURTLE SMART or TURTLE MANUAL trigger.

How to install the TURTLE trigger?

First of all, you should check the space in the housing. You have to measure the distance between the connector to the adapter and order a special cable. After the products arrive you just put the controller in the hot shoe, setup that from PC software, turn it on using the main switch, and connect the special cable to the device.

You can find the USB setup manual in the webshop (right side menu).

How the TURTLE is made?

TURTLE triggers are made from special SMD technologies parts to ensure it can be as small as possible. The TURTLE triggers' case is made of ABS molded plastic, so they are light but durable.

The hot shoe was made from PCB with special spring-loaded pins to ensure the optimal connection with the camera. All triggers have a LIPO 120 mAh rechargeable battery. To recharge you can use a micro USB cable. (From May of 2020 we add a charging cable to the TURTLE triggers.)
