I haven't tried the "save for post processing" button attached to the accept as yet. I will today if I get a chance. I always have the same profile set in my stake screen as I do in my collect screen so I'd have my PPK set for 15 minutes.
I know not many do a lot of "collect" while in "stake" screen but we do that quite a bit and I think Nate does as well.
The reason I can use this feature is we almost always have design points we are staking to and let's say I've translated and rotated a batch of 20 points on an existing survey from a known local surveyor who's work is typically very good to follow. After I get a few points, I'm consistently tying into his points within very reasonable tolerances. Then I get to one down in a deep dark hole, that's where I like to be in the stake action screen instead of collect. If my first couple of epochs gives me a DTT of 3.5', I'm pretty sure that's wrong. Then a couple more come in and my DTT changes to 6.4' - still not it. Finally after a few minutes I might get a bucket of 3,110,2 and my DTT will change to 0.13' or something similar. I immediately know that is the correct coordinate. This just gives us immediate feedback in the field - both of how "tight" the survey we're trying to follow is and if we already know it's good, it gives us more confidence quicker when the shot is harder to acquire. If that shot ends up taking 15 minutes, then I wanted the ability to store that raw data as a PPK point. The LS was already collecting it - I just couldn't use it until the feature was changed.
Another situation where we use this is staking to line. Sometimes those shots as well may take a long time and I like to store the coordinates of the stakes I set and the same thing applied. Before, I couldn't use/store any of the raw data collected while in stake mode - now we can.
This is what's so fantastic about this equipment, not everyone uses it exactly the same. There's definitely more than one way to skin a cat with the LS!
