I would like to take just a few minutes to pass along my observations of the Gitzo GH3750QR.
Before I begin, I will mention that the product mentioned here was purchased by me and not given or loaned. I used the product in the field for a number of weeks, or at least up until I switched to an Acratech GP-s Ballhead. Reason mentioned in this review. The Gitzo head now sits on my desk as a paper weight.
