Swing speed analyzer

You are looking for a launch monitor if want those metrics, not a swing speed analyzer).

I will recommend three; For a budget option, the PRGR Portable Launch Monitor, the Foresight Sports GCQuad would be my suggestion if you were not concerned about budget, and the Garmin Approach R10 is probably the best value.

All can be found new, on e-bay and facebook marketplace because plenty of people buy them and realize they're not worth the hype. Find an indoor place like Loft 18, log in a couple sessions, get the data and go back once every few months to compare OR invest in golf lessons where you can get the same info AND the benefit of improving your swing and game rather than just feedback on the results of your swing.

PRGR, stack radar or shotscope are all good options around $200
