Why did I wait so long‽

For my style of landscape and wildlife photography, leveling with a bowl and half ball is the only way to go. I can’t believe I waited so long to purchase something that completely streamlined and simplified my setup. The ability to stabilize the tripod however I need to, and also be able to throw it up fast if the light is changing without worrying about getting each leg exactly right is a game changer. Let your sticks (mine are TR343 since I am short) be as wonky as they want to be, and still be perfectly level in seconds with this leveling head! Currently being used to watch a nest of wren eggs in our garden.

Thank you sending me the leveling head with the updated one!

I ordered this leveling head for my TR344. I didn't expect you'd send me the one with leveling spirit. It's a surprise gift to me. Thanks!!

Where have you been all my life?

I recently got the leveling ball for my tripod. Prior to receiving it, I would have to achieve level by lowering a leg or two, in increments, which is not ideal. Now, all I have to do is get close to level with the legs and finish off with the leveling ball. What a time saver! This device is a life saver when trying to achieve level with the Katana Jr. The Jr. has a nice big leveling bubble that is easy to look down on so the leveling ball is a cinch to adjust with. No more wonky horizons when panning. The picture of the eagle that is attached was taken with the Katana Jr. And the leveling ball. I snapped off 10-15 frames before the eagle disappeared and I think at least 3/4 were sharp. I owe a lot to the Katana Jr. and now, also, to the leveling ball.
Thanks for another great product ProMediaGear.
P. S. I have reviewed a number of ProMediaGear products but ProMediaGear does not sponsor me nor have they provided any demo units. I purchased and own the PMG gear I have. All opinions are mine, accurate and honest. So far, every product I have purchased from PMG has met or exceeded my expectations for quality and performance.

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... :)
