Yeah this is the cheapest one currently available as I wanted to move to a watch for running/cycling and don't need it to be *that* accurate since I just want to track progress over time and I'm not going to be setting records. Being able to toggle the GPS on/off for cycling is a nuisance but I can live with it for the budget

If you're stationary and the GPS is enabled and locked, I could see that doing really strange things. I never had an issue with my 510, but it usually couldn't acquire satellites indoors.
That's pretty interesting; so in theory using both on a run outside should give me a better calibrated speed sensor to use indoors too? The speed sensor was set up using the app and the ETRO number on the side so may be a bit off. I might just leave it on and see what happens then.
