  1. Eric, this was expalined to me by some one much smarter then me. There are two GPS signals sent from the satellites. The most commonly used is the positioning one to find where you are on the earth and you are correct it's not very accurate although I was told it can be within three feet. The second is a time/distance based signal which we use to control the actual speed. It's accurate but dosen't know where it is, just how far it has gone from the setpoint.

    The reason the beep is not always in the same spot is that the speed control uses the positioning signal to locate the course, and it is only accurate to at best the three feet mentioned above.

  2. First off, a -.09 is fast not slow so I'm assuming you meant +.09.

    Are you setting up the skier weight factor, Feather, Light, Nomal, XL befor you ski each person ? If its on no skier or too light it will show a slow first segment and then take off once it does the first calculation of speed.

    To set the factors press on/off & up keys together, use menue to move up and down the list. Press the up key to bring up the b1, b3 ans b4 to exit settings. Increase the numbers for a fasrter segment.

  3. The Response hull is quite slippery ( good fuel economy) but that make it harder for the speed control to maintain exact speeds.

    Coming in slow ? Do you mean below 55 at no load into the pregates ?

    My 95 Response was surging a little after ball ,1 so I set ball 1 to be .01 fast. Now I have no surge. Times usually come in -.01, +.01, -.02, -.01, +.01 at 16.95 so the last ball must be +.02. All at 32 to 35 off.

    Having a fast segment seems to slow down the next.

     

  4. @lff - sorry. No it's not a problem, a friend of mine is a chemical engineer he reminds me that pretty well all metals rust or corrode in some fashion. On a nibril prop, the corrosion just gets polished a little black due to the forces. Different water will accelerate this. If it was excessive cavitaion, thager has got it right (pitting on the prop also.)
