Below is an email I sent to PP tech support, but just thought I would also share it here in case anyone has had similar problems.
I have a Stargazer 8 system that I upgraded over the years to version 9.21 and have zbox.
On our lake we have 2 ski courses.
One runs West -- East, and the other runs NorthWest -- SouthEast.
Occasionally, just as the skier gets up, the GPS signal is lost and the boat runs away into the course at super speed!
The lost GPS signal seems to happen more often running the course into the West direction, and the NorthWest direction depending on which course I'm at.
The puck is installed flat in front of the dash, just behind the windshield and front speaker.
(2003 Malibu Sunsetter LXI)
Once we get to the end of the course and turn around, the signal locks in and works for the next pass going the other way.
Is there a better area to place the puck? Or any other options to try?
