Yup. And you can extract the feature vertices as points in ESRI or QGIS to get the points out. You can do point "nesting" in TerraFlex similar to TerraSync. It's a bit different though. While inside a feature/form, you can back out in the top left, hit the plus to collected your nested point, line, or polygon, then submit your nested feature and resume the line.

Oh, that's good to know re: line features - thanks! I do occasionally use lines instead of relying on the tracklog. The problem is remembering to start a new line after every point feature - in good habitat, I'm collecting several points on each transect, so it would be a lot of starting & stopping. And I suppose filling in many "forms" that we don't actually care about (we'd only need the date & maybe the time). When I've used lines in TerraSync before, it's just a little extra down-time every time I find something to 1) stop my line, 2) collect a point / fill in data, 3) start a new line, & 4) go back to Map view before I can start walking or flying parallel lines again. Minor, I know, but it adds up. (Especially when a helicopter pilot is trying to hover, waiting on me to start surveying again!)
Anyway, knowing the .csv files aren't going to eat up all of our memory is great - thanks. TerraFlex is still sounding easier, or at least more familiar, than the Field Maps option.

It is practical to use as a back-up but I would not necessarily lead with it. That being said, it's fairly consistent at 1 second. You should not worry about file size, as it's a CSV. You will find that you'll likely get several CSVs over a days worth of collection. The breadcrumbis not configurable but you can configure a line template to log at every X distance or X Time.

Hi, Zach, that video was really helpful - thanks for that.
Just wondering if anyone has used & exported the TerraFlex breadcrumb trail enough yet to have a sense of how practical it is to use & download (or at least sync) every day? Can we not set the logging interval to use distance vs. time? We track ourselves while conducting rare species surveys every field day and sometimes have to submit a shapefile of our transects as a project deliverable. This need for a tracklog has been one of the biggest reasons we have been clinging to our Geo 7Xs, TerraSync & Pathfinder Office for dear life - I'm just not convinced that any of the current options in TerraFlex or the "Mobile Workers" option in Field Maps are going to be as simple & reliable as just pressing "Play" in TerraSync & checking one box in PFO!
For any ground work we do, I have our Geo 7Xs set to log at a 1 second interval for any *features,* but the between-feature logging is set to 16 ft. (the highest option). A lot of my day is spent staring at potentially rare plants, barely moving through muck or dense shrubs, etc.; a point every second would make my .ssf files even more huge than they already are. (We change that interval to 1 second when doing surveys via helicopter.) If the only option for the TerraFlex breadcrumb trail is to log every second, what kind of file size does that result in, and can we pause it / uncheck the "Breadcrumb Logging" box when moving between survey areas, etc.?
Also, I'm sure there's an ESRI tool out there to connect the dots to make a line feature later, but if anyone already has a workflow for that, I would love to know that, too! We currently opt for "One line per group of Not in Feature positions" in PFO.
Thanks for any help.

Thanks Zach, that was the first video I watched and I couldn't figure out why my breadcrumb folder wasn't popping up. I thought it was supposed to appear after an export, but I think it is auto populated with a sync to Trimble Connect. Turns out that I need to move around a bit to get a breadcrumb trail.

Scott,
The breadcrumb CSV should show up in in TerraFlex on connect in a folder called "Breadcrumb Files." I believe it's 1 pt ever 2 seconds or .5hz? I would look closer, as I am still getting positions in the CSV from where I am standing still on control. Also, check out this video that we put out on the latest TerraFlex enhancements (breadcrumb files and auto-fields): https://youtu.be/ys4bT1g_S84.

I'm trying get breadcrumb trails working with our DA2 and Terraflex on iOS, but the system doesn't seem to be logging. I have both "Show Map Breadcrumb" and "Breadcrumb Logging" enabled. I'm using a point collection form as a starting point. Trimble Connect only has points after syncing and I can't see breadcrumb trail on the map in the Terraflex app. I'm not moving, just feeding the DA2 from an indoor GNSS relay from our rooftop antenna. I would expect to see a cluster of points scattered.Perhaps I need to be moving? Suggestions? Shouldn't there also be an option to configure 1Hz, 5Hz, and 10Hz positioning rates?
