Cartography - gps, garmin


Before buying this new Venture HC, I had spent many hours trekking with several of the original eTrex models over the years. I think it's fair to say that while the concept of the original eTrex was great, the execution was frequently disappointing.



It disappoints no more. The Venture HC is the eTrex perfected. It remedies almost every shortcoming that plagued the original models. The new high-sensitivity receiver is amazingly effective. Countless times I've stood in wide open spaces cursing my old eTrex because it wouldn't acquire a single satellite. Last night I turned on the Venture HC on the bottom floor of my two story house, and it locked onto 8 satellites...through the roof and the upper floor! No more "need a clear view of the sky" messages. Amazing.



The old monochrome display has become color, and the user interface is now substantially more intuitive, while adding even more functionality. The cable, which was serial on previous models, has been upgraded to USB, another welcome improvement. The case is somewhat wider than before, but the design bears a strong resemblance to the original eTrex.



A basemap is included but it's just that - basic. It shows the largest highways, bodies of water, and has some limited capability to display highway exit services. If you need turn-by-turn street directions, an eTrex is not for you. This is a GPS receiver true to Garmin's outdoor GPS heritage.



Promised battery life (14 hours) is near the bottom of the range when compared to the existing eTrex models, but is still perfectly adequate and has posed no problems.



One weakness that remains is Garmin's waypoint manager PC software. It has the feel and functionality of a software product released circa 1994. Garmin could certainly develop a better PC interface. For $49 you can buy ExpertGPS from Topografix, or download the free version (EasyGPS)from their website. Either is far more functional than the Garmin OEM software.



Still, the software criticism is a quibble. The Venture HC itself is great. It is a market changing product that renders all previous eTrex models (and many competitors) obsolete. Finally, an affordable outdoor GPS receiver that I can wholeheartedly recommend. Garmin eTrex Venture HC GPS Receiver

I was totally chessed off at Magellan when my Explorist 100 died under warranty and they refused to support or repair it (this was a new unit!). So I only considered Garmin based on liking my car unit.



Mac Users:

It's a bit tricky, but I am able to use the USB cable and the 'send to Garmin' to automatically load waypoints from geocaching.com. One warning is that they have a Mac firmware web updater and it's very new and froze on my attempt to use it, which blanked my unit. [...]. I did the update for this unit on a friends PC and it went fine.



There are some Mac caching software, but none of them are working for me with this unit. So keep that in mind if you really want to go beyond the web waypoint downloads. That's a bummer, since Maccaching and GeoJournal look like they'd be great.



The included software does not work on a Mac, so ignore that CD. From the Garmin site, you can download the plugin for Mac to make Safari aware of the unit so you can do the "send to Garmin' trick. They also have the Mac version of their WebUpdater (the one that hosed my first unit) on their site. Finally, you don't need any USB drivers for Tiger or Leopard OSX, so don't worry about them only being for Windows on the Garmin site.



Usage:

Crazy fast turn on and acquiring satellites. We are thrilled that we can turn it on in the car and it will start to pick up satellites right away. Our Magellin (an cheap 100 unit) would take awhile even outside in cloudcover.



It also seems to save all the time, as the shutdown is very fast, with no 'saving' note like our Magellin made us wait for.



I guess our only complaint is that we like to use the backlight a lot and that sucks batteries. It's winter now, and so many days and locations are dim, and without the backlight, the unit can be pretty dim to read. It takes 2 AA's. It also has a system pref for the type of battery you use (Alkaline, NiMH or LiOn), why? Maybe to only USB charge when they are NiMH's?? But remember to set that to the correct type.



We really love auto loading the coordinates. And even with the free account on Geocaching.com, we get the cache name, GC# and coordinates. That saves tons of time and mistakes. We find ourselves loading up any cache that interests us, just in case.



Accuracy:

The unit seems right on. Our other unit would usually be more like 20-30 feet accurate in the woods, and this one led us right to the cache and showed 16' accuracy at that point under normal tree cover. It also refreshes more often than our old unit, so it feels more responsive. No more going 20 feet and then seeing that the arrow just didn't update to show we were going the wrong way, or overshot.



Build:

It seems solid and took our last rainy hike well. The back has a bit of a gap, but the seal must lock in fine. It uses the 'D' lock, so just half a twist to lock and unlock, which is fast and appreciated on a cold cache while changing batteries. We always had to dig to get the Magellin's ring out and turning to pop the back.



Thumb toggle:

If you've used the old Garmin's with button input, the toggle on the front is really welcomed. We zip through data entry and you push the toggle in to accept an entry. It's also a shortcut to Mark your current location (holding down the toggle button). Another tip is that holding down the lower left button brings up the 'Find' menu quickly.



Speed:

One thing I noted was that when I went just one setting more on 'detail' for the maps, it really cut the redraw speed (which is a tad slow to begin with), so that was disappointing.



Hope that helps someone and happy caching!
