For the lucky dudes who own this machine, is tension adjustable to 0.1 lb?

Pete, I'd be extremely surprised if it isn't. But, IMHO, the more important feature is its tension sensitivity when the constant pull is on. IOW, how much deviation would it tolerate before it re-pulls (e.g., 10%, 0.1 lb., 0.5 lb., etc.). Because even if you can adjust to 0.001 lb., but the mechanism is not sensitive enough to detect such a minute change, then the final resulting tension wouldn't be anywhere near what you set it to be.

Speaking of which how's the Wise Head holding up? Is it sensitive enough?

Gamma 8800 ELS
I read the tennis forum reviews but haven't found much about user reports about this machine. Have you heard anything in your area?

8500 & 7500 have load cells and re-pull around .5-1 lb drop.
8800 & 5800 are digital and have a spring and re-pull around .5-1.5 lb drop.
6500, X-Es & EsII+ are mechanical and have a spring and re-pull around 2-4 lb drop.
The 5800 & 8800 use a digital encoder that is attached to a "car" and pushes against a spring to sense the tension. It has been very good and I haven't heard any comments or complaints about it. The tension is also set electronically.
The 7500 & 8500 use a load cell to sense tension. The motor applies pressure to the LC and sends a voltage, the voltage corresponds to a tension. The load cells are a lot more sensitive to temperature & environment. It is harder to mount the LC. Tension is set electronically.

By the time I clamp on the indicated tension is usually within 0.2--0.4 lb. of the set tension. I tried asking Mr. Wise about this, but he didn't respond.
As for the new Gamma machine, no, I haven't heard any feedback about it. Considering Gamma's reputation it should be quite good. Although, I've read some comments about how it'd compete with the Babolat Star 5, which is "only" a couple of hundred dollars more.

Star 5 is only USD3,000 in the US .

I have the Babolat Star 5 presentation. It says the tensioner is accurate to 0.22 lb. Does that mean the tension sense slack and re-pull at 0.22 lb?

0.22 lb = 0.1 kg
Maybe it means you can set the tension in 0.1 kg intervals.
Maybe it means if you set a tension of 10kg you will get a tension
somewhere between 9.9 - 10.1 kg
