Frequently Asked Questions
Does the SeaLife 1/4-20 Adapter work with all GoPro cameras?
It is designed to be compatible with GoPro cameras, attaching with the thumb knob and bolt from the original GoPro camera mount. This lets you add a standard 1/4-20 tripod mount to your GoPro for use with trays, lighting, and other accessories without needing a different mounting system.
Can I use this adapter to attach my GoPro to a Sea Dragon light or AquaPod?
Yes. The adapter's included 1/4-20 mounting stud allows attachment to accessory bases such as the AquaPod and Flex-Connect Handle, and it integrates with SeaLife's Flex-Connect system used to expand Sea Dragon lighting setups with grips, arms, and trays.
What is the difference between SeaLife SL9817 and SL9818?
SL9817 is the 1/4-20 Adapter for GoPro cameras covered here, designed to add a tripod mount for trays and accessories. SL9818 is a separate SeaLife Action Camera Mount intended for SeaLife's Micro-Series and ReefMaster cameras, not for GoPro cameras, so the two are not interchangeable.
Are the mounting stud and acorn nut included with this adapter?
Yes. The SeaLife 1/4-20 Adapter ships with a 1/4-20 mounting stud and an acorn nut included, in addition to the adapter itself, so you have the hardware needed to attach it to compatible camera bases and Flex-Connect accessories.
