A friend of mine just sold his GPX Pro 4 for like $280. If you can find a used one for a good price, it would be worth it still, but I wouldn't spend a lot of money on something that's not being made and supported anymore. However as JD pointed out, they've announced that the company is closing so I don't know that I'd want to buy a product that you can't get much or any support for. In my opinion, if it gets within +/- 2 meters, it's pretty damn good.Īs you probably saw in this thread, I've been an advocate for the XT Racing GPX Pro unit, because it really does work awesome, and I really like it. Keep in mind no GPS is perfectly precise. When overlaying it with satellite view of the track (via google maps) it would show that I went off track in some turns and it would do that a lot. The Starlane that I had before was way worse. For example this is about as bad as I've seen with mine and it took me some digging around in the last 10 minutes to find a few laps where there are imperfections like that. I haven't seen a unit yet that's perfectly accurate, but it's not bad. You're talking about the trajectory line that you see with the software after you analyze your data? If so, yes there will be some imperfections. That would've been a steal!!Īhh I think I know what you mean. It required a few tweaksto the speed conversion (set it to 0.65) and the lap time you need to set the se. If you can find a used one for a good price, it would be worth it still, but I wouldn't spend a lot of money on something that's not being made and supported anymore. I used the software RaceRender to apply the overlay. That's just for shits and giggles for you to look at when you want to compare multiple laps.Īs you probably saw in this thread, I've been an advocate for the XT Racing GPX Pro unit, because it really does work awesome, and I really like it. It doesn't matter what the trajectory looks like of the lap. So the only error you get is from the GPS error if it thinks you're a bit farther back or forward than you actually are when you're crossing the line. In my opinion, if it gets within +/- 2 meters, it's pretty damn good.īut as far as the actual lap times go, those are simply calculated from the time you cross to finish line, until you cross it again.
