<div class="moz-cite-prefix">Hi Andy,<br>
<br>
Thank you. It was helpful. <br>
<br>
It is definitely better than a smartphone, mostly to the battery
(14-16 hours) & EGNOS correction. I learned how to install the
OSM map on the device, - basically export/copy/paste the .img
file.<br>
<br>
I also acquired an accessory, - a big aluminum clip to attach the
device to a backpack. It is quite convenient to keep it outside,
well visible to satellites.<br>
<br>
Best regards,<br>
O.<br>

<p>Whilst it's great that Garmin are offering the convenience

, and these might be an easier place to start reading than the

</p>
<p>I do have a GPSMap64s with preinstalled Garmin maps* that
aren't OSM-based. One problem with those is that they contain
lots of old, inaccurate non-OSM POIs that it's impossible to
turn off without removing the SD card - hopefully your OSM-based
maps from Garmin won't share this problem.<br>
</p>
<p>Re EGNOS on an Etrex 35, assuming it's similar to an Etrex 30x,
it's noticeably more accurate (within a few meters as opposed to
a few tens of meters) when you're somewhere with WAAS/EGNOS
coverage compared to when you're not (in my case it was Europe
with and Australia without, but that was a while ago - don't
know if the Australian situation has changed).</p>
<p>Barometric altimeter (on both Etrex30x and GPSMap64s) tend to
be accurate to within 10m at the top of the hill if you've
calibrated them at the bottom, but not if you haven't (apologies
for being Captain Obvious there!).</p>
<p>Battery use on both Etrex30x and GPSMap64s are something like
"one pair of rechargeable AA batteries every day and a half" (if
it's on all day).<br>
</p>
<p>Re the new 66s my understanding is that it can use 2 of
GPS/Glonass/Galileo at the same time. Personally I'd wait to
see a "review involving OSM-based map use" before getting one,
but I'm sure they'll appear fairly soon.</p>
<p>Other non-Garmin options for "something to last all day" might
be an old phone with GPS in it and user-removable batteries. An
old Blackberry might be an option (they still work after you
manage to drop them on the floor, and you might find the
keyboard more usable than a touchscreen when it's cold).<br>
</p>
<p>Best Regards,</p>
<p>Andy</p>
<p>* at the time this was essentially "free" due to availability
and what stock the various discounters carried - in theory its
about £60 extra, and probably isn't worth that.<br>

I also received an email message with an advice to acquire
Garmin eTrex. I've ordered the Garmin eTrex 35 Touch with the
pre-installed «TopoActive» Karte Europa, which is based on the
OSM data, as I understood:<br>

<br>
It supports the EGNOS, European Geostationary Navigation
Overlay Service, which is supposed to correct the GPS signal.
I have no idea how it works in reality. It also has got the
GPS and barometric altimeters.<br>

<p class="MsoNormal"><span lang="EN-GB">To answer Oleksiy’s
question, I record with OSMand on a Moto G4 smartphone,
that works like a charm. Off course there is fluctuation
due to accuracy errors, I guess 10-15 m is achievable
most of the time, but close to near vertical mountains
it becomes much worse. <o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">It however does

when <15% battery charge and Android automatically

set battery saving mode to off. <o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-GB">Also OSMand does not
drain the battery much. Usually I do take a lot of notes
which OSMand attaches to the gpx and loads perfectly
into JOSM. Recently I also used the voice recorder of
OSMand, which really speeds up the note taking while on
the go in comparison to typing. These also load into
JOSM via the gpx, but some fiddling with the location of
the audio is required. Taking notes on the phone does
have an effect on the battery life off course. A 20 km
hike in the mountains easily takes 6-8h, which my phone
reaches most of the time on one charge in flight mode. I
do have a power-bank as back-up, and for multi-day hikes
though.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">Altitude

I guess the raw elevation data from gps fluctuates quite
a lot, and the data processing did not do a good job
filtering errors from actual elevation change. After a
hike with 1000m elevation gain according to the map,
OSMand often showed I did 5000m... The graph of the
track you can generate in OSMand also showed a lot of
spikes with instant ascents of >200m. Recently that
seems to have changed and the measurements seem to
better represent the actual situation.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black" lang="EN-GB">Hi
_dikkeknodel,<br>
<br>
I have a question - how do you record a GPX trace during
20 km walk? It should be about 4 hours. <br>
<br>
I also record GPS traces but usually for 15-20 minutes.
I use a phone with the OSMTracker app for Android with
mixed results. Sometimes it records a path well,
sometimes it turns the second part of the walk into a
long direct line. Such a trace I usually discard.<br>
<br>
Besides it empties the phone battery rather quickly. I
usually take a power-bank with me, but still it is not a
good solution to get a phone battery empty in mountains.<br>
<br>
I am thinking of getting a dedicated device which can
record the GPX files, on the OSM map, and also measure
and altitude more or less correctly. The question is -
what device, what model.<br>
<br>
Best regards,<br>
Oleksiy<br>
