@amisuraca Club Champion charges $350 for a 3.5 hour full bag fit. That should be a pretty good ballpark figure for you.
In many instances, you can get fitted at a golf center for $200-$300. In many instances, if you purchase the new clubs from the golf center, they will reduce the cost to $100-$150. For my last fitting, it ended up costing me $150 for the fittings because I purchased the new set from the person who fit me.
There was one in particular in the central Florida area I was going to use, but due to a scheduling issue I settled for a Golf store chain to do the fitting. I wish I had waited. This fitter was one of Golf Digest top 100 fitters in the US. A full bag was $400, but that was broken up into 2 or 3 sessions on diffeerent days. The reasoning was after 4 or 5 hours, fatique would be a big factor and effect the results. Do your homework. Good luck.
I paid $100 at the Callaway Performance Center in Carlsbad. And not only that I got $100 off when I bought the clubs--They were really great and worked through everything with me and I am really excited with the purchases...
