I’d be Leary about using an aftermarket gimble guard, the OEM one holds it the way intended. I wouldn’t risk damaging the gimble. I use aftermarket ND filters and just put the clear UV filter back on. Sorry to not be of help.
I have the PolarPro gimbal guard and can assure you it is far superior to the one that DJI builds. After cracking off the mount point on three or four stock DJI mounts and having an authorized DJI store tell me to not waste any more money buying that product, I’m sold.
Thanks for the responce. I did notice a few aftermarket ones after asking the question and have been leaning towards the polar pro. It may work with other nd filters as well. Thanks again for the response.
