Problem picking up club speed on woods but not on irons with GC3

[lavandlerh]

My GC 3 quite common misses to pick up club speed and AoA with my woods but never with my irons. Does anyone know why and how to fix it.
Have single dot on booth clubs

[stubious]

Can't speak to it personally, but have seen others suggest a) new dot and/or b) adjusting ball position relative to the unit.

I have done that and changes dot very often on woods and it works for some time but I never need to change any dot on my irons, they are almost 6 months old or more

Try using 4 dots per the GCQuad setup, see if that helps. Can you post a picture of the face of your driver? Reflectivity might be an issue.

It works better when adding 4 dots Thx

[lavandlerh]

Will try that and add picture on my drive
