BadElf BE-GPS-2200 GPS with Display and Data Logger Bad Elf Pro

Product Information

I know what my choice would be, but obviously it’s a trade off of simplicity (and possible connectivity) versus GPS high performance and logging capabilities. iSailor not only opened up and imported log data from the Bad Elf app, but it also handled the whole 28,782 point GPX file, which is several megabytes big. Then it'll correct itself, but usually over-correct, so that if it was 50 meters to the left it will now be 70 meters to the right of the actual track followed.

Plus this Bluetooth Elf can do much more than simply feed position data to iPads, Touch iPods, and iPhones (up to five at once). Bad Elf is brewed by Peter Scholey, master brewer for the late and much-lamented Brakspear Brewery of Henley-on-Thames, England. However, the accuracy at best will be like 5m, while my Android phone, for instance, might get 3m accuracy. That’s last part of the automobile section overlaid on the chart above along with short drive I logged at 10 Hz yesterday (they match nearly perfectly). It won't maintain a fix for more than half a minute or so, and the accuracy will occasionally reach sub-1m for a second or two, but it doesn't seem to be logging any of the points I'm trying to record, and I wouldn't trust them even if it did since it regularly shows 0 of 0 satellites connected while reporting sub-10m accuracy.I did not realize the situation when I retrieved the anchor and a minute later we were drifting down on a fishing vessel anchored nearby unable to use the engine.

The only problem is the IPad needs a cell signal to download maps unless you have previously downloaded any charts you may need.I’m not saying that those accuracy figures seen on the Bad Elf GPS Pro are absolutely true — without a physical reference point, a GPS can only estimate its own positional precision, right? Baseline Equipment Company is a full line dealer of Land Surveying Equipment and Industrial Safety Supplies. Today I also asked Bad Elf about Android support, but I wasn’t very optimistic as iOS does Bluetooth differently and the Dual xGPS has a physical switch to go from iOS to other operating systems.
