The GPS antenna patch interference issue is obviously not exclusive to the Vision series. Call it anecdotal or what you want, the proof is in the pudding for me. I never have high satellite lock issues and lock in sats (7 or more) at about 30 secs unless performing to what Ianwood is referring to as a Cold Start, and that takes only a few seconds longer. Some who have tried this noticed little or no improvement. Many, like myself, noticed a great improvement. Kind of like treating cancer right? What might work for some, might not work for others. My suggestion is for people with GPS lock problems to try it and then they can decide for themselves wether this mod works or if it doesn't. If it works then you have a faster, cheap, easy fix without the need to solder anything done with household materials. If it doesn't then they can move onto the GPS Antenna fix or a newer copper shield. I agree with NO17RW that his method of testing is anecdotal. You wouldn't be able to tell much if you do not have any form telemetry sending that info back to you other than going off your lock in times and lights. I do. How accurate it all is is another argument.
Steve said it takes him MINUTES just to acquire 6 satellites and rarely sees 10. I had that exact problem. If I remove the foil then it goes right back to the way to was before. I personally wouldn't want to fly like that. Maybe it would benefit someone like himself and maybe it wouldn't. One way to find out. Definitely not through guessing, theories, or hearsay.
