Golf Aids Help Or Hinder

Not to long ago I posted a video about Vijay Singh and a device he uses for his swing tempo. Most if not all golf pros have some sort of gadget to help with their golf game. Hell most hacks like myself have a few as well. Have things gone to far. Bobby Jones never had a new fancy swing device to help with his swing nor did any golfer back then. The putting aids, swing gloves, talking watches, and swing helpers may actually help short term but long term if your swing sucks is a coach the only real help. Let me know what you think.
