Confused on Silent Partner Jive Electronic Tensioner description

4) Are all electronic machines based on the same technology?

Important differences distinguish the technologies used in various electronic machines. There are four types of technologies. The first consists of electronics for direct torque control of a motor so that the motor cannot pull more than the desired tension. Silent Partner holds a patent for this technology (US Patent #6,162,139) and offers it exclusively on the e.Stringer, the e.Stringer CL and the e.Stringer FL, as well as in retrofit tensioners for other brands of machines. The second type of electronic technology consists of a motor control linked mechanically to a pre-loaded spring. Tension adjustment is effected by turning a knob that compresses the spring to the desired tension so that a limit switch is tripped and the motor is stopped when the tension is reached. This type of control, which is identified by a tension control knob located to the right of the machine (see picture), does not provide constant pull because tension has to drop by more than 15 lbs for the limit switch to turn the motor on again, and this does not normally happen during stringing. Quality pre-loaded spring machines such as the Jive offer a string pre-stretch feature that achieves tension stability in the string similar to that achieved by constant pull machines. The third type of electronic technology is relies on a potentiometer monitored by a microprocessor. This technology offers the potential for many keypad controlled features as well as constant pull. This is the technology used in the e.Stringer DG. The fourth and most sophisticated technology uses a load cell and microprocessor. This is the technology used in the Silent Partner Aria and the new Silent Partner Opus.

I don't fully get it. Is it supposed to be like a lockout machine but with a electronic motor doing the work? And what are they saying about the pre stretch function? Like is it always supposed to be used?

Pre-stretch is an entirely optional function. Some people request it, so it's there. The value of a pre-stretch function on any machine, JIVE or otherwise, is debatable.

They ARE saying that the JIVE is an electric lock-out.

I see. I wonder how fast it is.

I dislike rotational grippers, and I really don't trust the robustness of an electric motor at this price point. When you talk about speed, what do you wish to compare it to? With the rotational machines I've used, they are faster than a drop weight but not much faster that a crank when I string.

I meant compared to a crank. I see, I probably wouldn't get the Jive then because w/o constant pull, I could get a better crank for cheaper with less bells and whistles to go wrong (i.e the motor, rotational gripper, etc)

Without true CP, I would have also chosen a crank. As you know, I passed on the MP Atlas 9600 because it is a lockout system. For lockout, I think the crank makes so much more sense. BTW, ordered my starting clamp from GSS and already received USPS shipping confirmation -- Tim works fast!
