Hey all,<div><br></div><div>Just like to check with you if there are additional experiences with loggers worth to take into consideration for inclusion in a hot hardware kit to be deployed in projects.<br>Curious about how the first two devices compare to the kind of res you get from garmin etrex legend hcx we have been mostly using in our work.<br>

</div>It's really cheap. However, my experiences with cheap devices is, that<br>
you can't rely on their results. One day, you get a good recording,<br>
and the other day you get complete crap. They use cheap chipsets,<br>
and - what's worse - cheap antennas.<br></blockquote></div><div><br>I see. Which means that it should supply HDOP values for it to be possible to assess the quality of the track.<br> <br></div><div class="im"><blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
If satellite positions or sky view is suboptimal, they start recording<br>
fantasy-coordinates. And you cannot tell the difference (you cross a<br>
mountain, one one side the track is accurate, on the other side it has<br>
up to a few hundred meters offset).<br></blockquote></div><div><br>Must say though, that my track didn't have any points diverging anywhere near more than 50 m, but I haven't really tested it much.<br> <br></div>
