Samson 4-73010-7 Tripod (retails for $676) and Samson 4-72011-6 friction head (retails for $319) capable of holding large binoculars, movie camera, or some OTA's (those which have base and fork. This was made for movie cameras. I used it with my Nikon 20X120 fork mounted binoculars. That outfit weighed 55 to 60 lbs, and that was probably right at or a little over the limit for this mount. I would not recommend this mount for loads over 50 lbs, but below that should be just fine. Shown in photo with Nikon set up.
$450 plus shipping.
