    Some Tennis Tutor machine models have so called 2-line feature, with two settings: narrow and wide. What do they do? The dial on the control board seems to indicate I can set the machine to:
    - oscillation off - I'm assuming it means it will deliver the ball to one place
    - oscillation random - does it mean it shoots the ball to random places both in terms of court-wide and drop shot -deep ball? Or is it random left to right only? Is there any way to adjust/tell it how random it is?
    - 2line narrow - does it mean it shoots the ball basically to fh and bh (of one player)
    - 2line wide - does it mean it shoots the ball basically to the left and right of the court so two players can practice?

    the models that have single oscillation setting - is it basically 'random oscillation' as described above?

    Also - is it possible to add 2 line functionality to a machine that has 'oscillation on/off' only (essentially I'm asking if the circuitry/mechanism is there and the dial is just not included but could be relatively easily wired.

    Yeah i believe two line is alternating shots from your forehand to your backhand side. So narrow will alternate from just to the right and left of the center line, whereas wide two line will be to the furthest right and left sides of the singles court so you will be doing alot more running.

    I used to own a Model 3 and Model 4 and the model 4 has a faster RPM motor oscillacion than the Model 3. So I don't think you can modify the circuitry unless you order a model 4 oscillacion motor and update the control panel to a model 4 control panel that has the 2line bottons. I think too expensive to do that.

    Good question on the "random" oscillation as to whether it will also toss "short" balls - which is often called "vertical" (depth) oscillation. If you want the short balls, make sure to verify whether the machine your interested in can in fact deliver them. More common, and for less money, is the "random" horizontal oscillation - which will toss balls to random horizontal (side to side) positions, but always at the same depth.

    2 line, as was mentioned earlier, is something entirely different. On Silent Partner machines, this is where the ball will alternate, either narrow or wide, to your forehand and backhand ALWAYS AT THE SAME DEPTH. The question I think your asking and wondering about, is the same one that concerned me. And that is whether and/or how to get the short balls. My guess is that most, or at least the more expensive S.P. machines, should mix in some short balls on their "random" oscillation mode.

    Can anyone verify how random S.P.'s random oscillation mode is?

    Sorry - I replaced "Tennis Tutor" with "Silent Partner" machines. I've got S.P. on my brain lately. The same questions and concerns are valid for ANY & ALL machines however. Make sure to verify and differentiate horizontal vs vertical oscillation.

    if you don't mind - what is Model 3? I'm assuming Model 4 is the one with top/under spin, and 2 line oscillation, but I've never heard about model 3.
