Now the ball GH100, I admit that I am rather disappointed, it is not very practical, plunged against the impossible, to unlock the ball must be an iron fist, which causes a lack of precision. My partner can not, she is forced to unlock the rear wheel which is not very practical, the level is under the sole housing fixing. This gives the impression of having been designed for the look and laboratory, without having actually field tested with a photographer.
I wanted to use the GH100 ball on my monopod Vanguard Tracker AP-284 a, it is unusable, I had to order a Vanguard SBH 100 ball, and just happiness, but it lengthens the bill.
You still have to know at Vanguard fixing soles are not compatible different ball of their range?
No need to try to Vanguard contacted by email, about it he does not answer?
In conclusion: For Alta Pro 263AT foot I fully agree this is really a great product.
To handle GH100 I advise you to try it before, the look is nice, but for me to use it does not seduced me, I also resell account.
Despite its name, Vanguard a Chinese product, and I confess that side finish nothing was wrong, by against a mode of employing more detailed'd be handy.
