I am now in need of a sub-meter accuracy GPS, and have been doing a great deal of research. If I had not had such a terrible experience with their cheapest device, I would consider getting their $600 surveyor model, because it has adequate precision for my needs. But instead, I'm going to pay hundreds of dollars to rent a real GNSS device, because there's no way I'm rolling the dice on another Bad Elf product. I know they didn't care about my experience because I was just some Shmoe who bought their loss-leader model, but a year later that experience is preventing me from even considering their high-end model.
When it works, it can get a slightly better fix than an iPhone GPS (about 1-3 meters better accuracy). It is really handy to have it recording constantly and it can record a ton of points per second. However, it regularly records wildly inaccurate locations (100s of meters off), or just records the point where I first turned it on, regardless of where I go. I've also found that the communication between the app and the unit isn't reliable, which may be the crux of the problem. I'll turn on tracking in the app, which will then show tracking enabled, but I'll later learn it was not actually enabled on the device. I've also found that tapping Save POI often does nothing, even though it looks like it did. I learned tapping it twice will typically get at least one POI recorded, or you can watch the face of the device to see if you see feedback--but half the value of the device is that supposedly, it can be in a backpack or resting on a survey monument within bluetooth range. To make matters worse, I only learned I didn't get good data after I download the recording which was after I'd left the field.
I contacted Bad Elf, had a brief email exchange where it became obvious that this wasn't a firmware bug but a hardware problem. Once it was obvious I needed a replacement unit, it was crickets. I've sent several emails to see if I can get any further response, but it seems clear that I'm stuck with a very expensive dud. So, all I can do is hope I save some other people from the same misfortune with this review.
The truly sad thing was that I was considering getting the Surveyor version of it to get greater accuracy until this experience helped me realized they won't stand behind their products.
My negatives are 1) accuracy. It rarely gets to the 2.5m (8’) accuracy even with a dozen satellite locks the norm is closer to 4.5m (15’) In fact, over my 9 years of using Bad Elf units the best I have ever seen was 9’ and that was only for a couple points. I took a sample of one million points and saw 12’ accuracy. None the less, far less than the 2.5m advertised. And the only way to improve that is to upgrade to the GNSS which advertises 1-2.5m which would mean spending 3X for an increase accuracy of 5 or so feet.
The second negative is you can only export data in the outdated KML or GPX formats. This takes some converting and cleaning before using in GIS
Even with the accuracy issues, this is the best unit I’ve ever used for for cost, size, and usability. It’s been my go to for almost 10 years and I will continue for many more.
I set the logging filter to 'walking' and the update rate to 5 seconds.
It was on *always*.
It used ~20% of the logging memory for the entire trip.
It never failed to operate for an entire day without charging.
It went two days without charging on two occasions.
It ran out of charge after ~36 hours without charging on one occasion.
It was able to maintain lock completely on most flights, intermittently on one (forget type), and not at all on the 787.
- Wish that it used micro USB.
- The battery indicator is not well-calibrated: it goes from all bars, to one bar down, to *off*.
- Would like to grab trips with Android devices rather than just iOS ones. Maybe they could publish the protocol so someone else (me?) could implement that...
In summary, this thing did what I needed with not much fuss.
1. No GLONASS: This is one of the few modern "GPS" units on the market that only use GPS and not a combination of GPS and GLONASS. This means that the acquisition time and tracking, while good, is not as good as it could have been. Bad Elf does produce another unit with GLONASS, but it is not easily available and it costs about 50% more, which is completely over-priced for such an ordinary feature.
2. Scratch-Sensitive Screen: The plastic clear display is not in anyway scratch resistant. It would be better if the protective sticker that came with it were completely transparent without inscriptions, such that users could leave it intact to protect the display. Or better yet, throw in a screen protector, or make the screen more scratch resistant.
3. Mini-USB not Micro-USB: The unit still uses the obsolete mini-USB adapter, which is almost unused nowadays. That means users have to always remember to carry an extra mini-USB cable on long trips, just for the GPS, rather than to share the micro-USB cable that we normally carry for all our other gadgets.
