Ihave a Vello Freewave Plus 2.4ghz radio remote purchased New on eBay from a reputable seller seller for $32 including shipping! Unit works GREAT !!..No issues good for up to 300 ft, and doesn't need to be line of site to activate. Nikon's top models have done away with the ML-L3 infrared system on their newer dslrs.
That's the one I use with both my D500 and D850. Good unit.
