Precision Pro
Learning from their past mistakes, Microsoft introduced the SideWinder Precision Pro in 1995, correcting the ergonomic issues, fixing some of the electrical issues, and adding new features.
The Precision Pro introduced a new stick that was far more ergonomic than the "geometric" design of the 3D Pro. Microsoft also gave the rest of the Precision Pro a more rounded design, replacing the rectangular base buttons with more rounded versions at the top of the base, the slider-based throttle with a wheel-based throttle, and the base itself was made more rounded. The Precision Pro also added a shift button to the base, doubling the number of possible button combinations.
Signatures can be seen inside the joystick, on the base coverplate. Fred Iyc and Edie Adams (User Experience Manager, Microsoft: http://www.affectivedesign.org/archives/151) are among the 17 people who have signed it.
For its electronics, the Precision Pro featured a refined hybrid system, resolving some of the hardware compatibility issues with the 3D Pro. However, with the widespread introduction of USB in consumer computers shortly after the Precision Pro was released, Microsoft soon re-released the joystick in a USB-compatible form (joysticks labeled as Part No. X03-57540, Product I.D. 85791-...). The revised joystick still featured a gameport connector but had additional circuitry for interfacing with USB, and was bundled with a USB converter (a DIY converter project exists). Original Precision Pros remain incompatible with this converter, a user made converter exists though. The creation of the USB converter bypassed the problems with the analog gameport entirely, and as a result became the true solution to the electrical problems. However, due to a flaw in the design of the Precision Pro, in rare cases the stick would build up a static charge in its electronics and require either a complex process to discharge that was not always successful, or simply needed to stay unpowered for a number of hours to slowly discharge on its own. This is also one of the first joysticks to use light sensors instead of potentiometers so it required no calibration, and thus had no electronical moving parts. The only moving parts were mechanical on the throttle and joystick pivots which gave this joystick virtually unlimited lifetime. The Precision Pro 2 had reintroduced potentiometers to save money and thus their lifetime was limited to wear and tear of the potentiometers.
Thanks to the timing of the launch of the Precision Pro to coincide with the widespread launch of USB along the ergonomic corrections and rarity of the static charge problem, the Precision Pro saw a much higher sales volume and review scores than the earlier 3D Pro.

Famous quotes containing the words precision and/or pro:
“Some authorities hold that the young ought not to lie at all. That, of course, is putting it rather stronger than necessary; still, while I cannot go quite so far as that, I do maintain, and I believe I am right, that the young ought to be temperate in the use of this great art until practice and experience shall give them that confidence, elegance and precision which alone can make the accomplishment graceful and profitable.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“The upbeat lawyer/negotiator of preadolescence has become a real pro by now—cynical, shrewd, a tough cookie. You’re constantly embroiled in a match of wits. You’re exhausted.”
—Ron Taffel (20th century)
