Very secure locking mechanism.
I BOUGHT THE PIN TO LEVAL THE SPIDER PRO TO ALLOW ME TO SET MY CAMERA ON ITS BASE AND NOT FALL OVER, IT NOW SITS VERTICAL AND DON'T HAVE TO BE CONCERNED THE CAMERA IS GOING TO FALL OVER. IT IS MUST FOR PRO USER TO BUY SPIDER PRO WITH TWO PINS FOR BALANCE.
I’m extremely satisfied with this purchase for some reason I misplace they original one I’m just happy for this replacement it didn’t take long for me to receive it thanks spider
Not the item I thought it was. I need an extra pin that fits the camera plate. Guess you can't buy them stand alone.
