Visual Cue for Metal Detecting

Suggestion: I think it’d be awesome if we could add some sort of visual cue to Metal Detecting? Like the faint beep is a red light, the faster beep is yellow and the fastest one (where you’re SUPER close) is a green light. I’m hard of hearing and I enjoy metal detecting on the beach but it’s hard to do when you only have one ear that works better than the other.
How will it expand RP: This is just a suggestion for those who are hard of hearing to make it more accessible for all.
