Compare the Flex-Connect Ball Joint Adapter and YS Adapter to choose the right mount for your underwater lights and accessories.
Quick Answer
Choose the Ball Joint Adapter for Flex-Connect if your light or accessory uses a standard 1-inch ball joint; choose the YS Adapter for Flex-Connect if your light or flash uses a YS mount. Each adapter ensures a secure fit with your Flex-Connect arms and trays.
Understanding the Mounting Standards
Underwater lights and accessories come with different mounting systems. The two most common are the 1-inch ball joint and the YS mount. Knowing which one your gear uses is the first step in selecting the right adapter for your Flex-Connect rig.
The Ball Joint Adapter for Flex-Connect is designed for any brand of underwater light or accessory that uses a standard 1-inch (25mm) ball joint. This includes many popular video lights and arms. The YS Adapter, on the other hand, is made for lights and flashes that use a YS mount, which is common in strobes and some older light models.
Durability and Build Considerations
Both adapters are built to withstand the underwater environment, but the Ball Joint Adapter is described as heavy duty and built for maximum durability. If you plan to use larger or heavier lights, this might be a more reassuring choice.
The YS Adapter offers a different kind of flexibility: it rotates left and right on its base and allows up and down directional control by angling the light on the mount. This can be handy for adjusting your light beam without moving the entire arm.
Trade-offs at a Glance
- Ball Joint Adapter: Use this if your light or accessory has a standard 1-inch ball joint. It offers a heavy-duty build and works with a wide range of brands. Check your light's mount type before purchasing.
- YS Adapter: Use this if your light or flash uses a YS mount. It provides left-right rotation and up-down angling, but it is specific to YS-mount gear. Ensure your light uses a YS mount, not a ball joint.
- Compatibility Check: Before buying, verify the mounting system on your light or accessory. If you have both types, you may need both adapters. Consider your entire lighting setup to avoid purchasing the wrong adapter.
