Great product, excellent quality, well designed and easy to install. It works perfectly with the TR424 tripod.

This is the absolute perfect addition to my Pro Stix 424 tripod. So glad you have modified the twist grip with the oversized rubber knob, which is a dream to use.

Works famtsicalky! Well made and appreciate the smoothness when panning. When on target and the system locks exactly there it’s aimed with a slight twist. We use this system for precision rifle comp. and it works flawlessly with our 17 pound shooting system.

Turely a must have for the GKJr or it’s big brother GK. Speed and ease of set up is a no brainer. Quality machined product, I expect nothing less from PMG. Good job boys! Only drawback we lost the bag hook... :)

I got this half ball leveling head along with Pro Media Gear's 75mm video bowl to use with my PMG TR344 tripod. They work great together, and the leveling head turns out to be portable to any other tripod with a 75mm bowl. I really like the build quality, the grippy adjusting knob, and the overall smooth operation. One thing I'd like to see PMG make (hint) is an accessory arca swiss clamp to use with the leveler that would allow quick attach/detach of ball heads, gimbals, etc. to and from the leveler. I'm extremely satisfied with this leveling base. Great job PMG!

I've been using this TRBU75 Pro-Stix 75mm Half Ball Leveling Head in conjunction with the TRB75 Pro-Stix 75mm Bowl Adapter on my TR424L PMG Pro Stix 77 inch Carbon Fiber Tripod and I highly recommend this combo. It is very well constructed, operates smoothly, and once locked into place it stays put with absolutely no slippage whatsoever.

The TRBU75 Pro-Stix 75mm Half Ball and the TRB3475 Pro-Stix 75mm Bowl set, is an excellent addition to the ProMediaGear tripods, making it easy to adjust the tripod without moving its legs, in an easy and fast way, extremely important in wildlife photography

When your tripod leaves the studio you'll want to have this (along with the cup) on your rig. Makes leveling a breeze. No more twisting and adjusting your tripod legs trying to find level. This makes it a 5 second exercise. Well build and very high quality. At first I thought it would be nice if it had a hook to hold additional weight but Pro Media Tripods are so stout it became obvious that a hook wasn't necessary. The Half Ball Leveling Head is worth every penny!

the half ball leveling head works great even with large prime lenses and super telephoto lens, easy to use lock in tight and you can still get the tripod to lay out close to the ground like all there equipment it is built to last a life time and the people who work there are great to deal with keep up the great work guys

Purchased with my 424L tripod and happy I did works so smoothly. Makes leveling a breeze instead of always trying to make leg adjustments. Machining and finish is outstanding.

I really appreciate how smooth the movement of this leveling head is. I'm going to try it as a limited range gimbal. I love the quick head change out on my 424L with this leveling head.

Very nicely built and works great in conjunction with my TRB75 bowl adapter and TR424L tripod. Very smooth action and easy locking. I will, however, be keeping an eye on the plasticized tension knob to see how well it holds up over time, but I don't suspect that I will be worrying too much about that.

When i bought my tripod i figured that this would be a good idea to buy this. I'm very happy with it it works great. It makes getting your camera level super east. Like the rest of Promedia gear stuff it's build very well top of the line gear.

Definitely a must have for fine tuning the leveling of the camera. At first I was concerned about no level incorporated into the plate but the one in the camera works just fine.

Very well made (as we have come to expect from PMG).

This item is very well built. Works perfectly.
