Full marks to Johnny Appleseed for getting a replacement shipped and delivered just in time for the OLT nine day stroll having to wrangle Garmin Australia into gear. Sure I had to turn up at Startrax on Friday night and ask them to dumpster dive their recent delivery bins but they came through. In my dealings with Johnny Appleseed I have found them excellent and well worth the extra Australian price premium, which from me is the highest praise. Meant a very quick setup time with OSM maps copied on. So how did it perform?
Well my Fenix had a fellow gear freak that we meet on the walk for company and it was interesting to hear his views. He also owns a Suunto Ambit competitor to the Garmin Fenix but (unsurprisingly to me) found it a very poor performer with ridiculously short battery life and complex user interface. So the Fenix came with him. His is an early production model as well. On the last day it exhibited the typical lockup and reset to factory settings when the battery just collapsed. Plugged it into one of our battery packs and it came back to life, but minus all the data. In typical style until then the Fenix was winning his affection. Sadly the Fenix reliability issues is rather typical of Garmin's "sports" GPS range. Frustratingly Garmin with their "industrial" grade GPS such as the 62S and Rino 650 are simply bullet proof but their sports models are very poor. So Garmin get your act together and pluck up the courage to recall the first batches. Ok, that will not happen as Garmin is notorious for denying problems.
So how did the new "improved" model perform. Well not great. At Frog Flats the screen started to fog up on the inside but then cleared and did not reappear. This is exactly the way the first Fenix's problems started. So much for the improved seals. The buttons to lock the display proved to be as "sticky" as the first one but experience has taught me not to give up and lightly tape the buttons and they will respond. As the trip went on this problem started to disappear.
Ok, you have fallen for the UL bug and decided that a Fenix is for you. Well battery life on the new Fenix was much better with six hours of walking and tracking still having sixty percent of battery life left. But you still windup carrying a large amount of storage batteries plus the charging cable so the UL aspect is bit of a myth for a multi-day walk.
But the big issue was the satellite lock time. Much of my walking is down up in the north of Tasmania rather than southern troll territory and many of the valleys run south to north so get a reasonable view of the sky with satellites but down in Pine Valley the unit struggled. The attached screen shot shows in green (teal?) the Fenix track and the Garmin 62S and Rino 650 plots. The straight lines are due to the Fenix not locking onto satellites. Puzzling the unit once locked in performs quite well. Worthwhile mentioning that the basic Garmin Extrex 10 locked in within a minute, in fact much quicker. So if you are depending on the Fenix as your only GPS then in deep east/west valleys you will be in big trouble locking onto satellites on start up and be much better advised to carry a much cheaper Extrex 10 or another dedicated Garmin/insert your favorite brand GPS.

- Fenix start up satellite lock can be dismal. Note Garmin's maps placement of mountains. Yeap, Garmin does not give a toss for peak baggers.
But if you treat the Fenix as a toy rather than a tool then you are rewarded with a great gadget. I had the remote wireless temperature gauge connected and it was brilliant tracking the temperature changes as the fronts hit. Temp would drop from eight to five degrees then rain would turn to snow and the windchill start pushing the outer-shell making you appreciate it and a base layer that remains warm despite becoming wet.
Having ready reference to distance covered and time taken made planning ETA easy for a group with walkers new to the OLT. This was especially useful on the long legs in adverse weather. I need to work on OSM to get zoom levels better sorted as tracks disappeared once past 200 metres level.
In all the Fenix is a great toy but a useless tool. Here is how it compared to the other GPSs carried by me. Again notice the location of the lake, and no I do not walk on water.

- GPS tracks compared. Anyone wants to walk on water buy Garmin's maps.
Cheers
