-- GPS For Hiking? (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=5587)

Looks like the HnadyGPS won't do for hiking. I would just like to set a "origin" point, and wander until I got bored, and then be able to escort myself back from there. I can do this already with a compass, but I'm looking for a GPS partly for novelty.

The driving/mapping software would help immensely as well, but I really would like a hiker's GPS with it.

I don't have a HandyGPS (yet) but couldn't you just make your starting point as a waypoint, and then when you are ready to turn around, set the waypoint as your goal?

(I played with the HandyGPS software)

Granted the map won't work too well, since it is based on streets, but I assume as long as the area you are hiking in is on one of the maps you install, it would work.

I may be wrong.....anyone else?

Yup. It'd work for that.

It's got a waypoint setting/tracking mode that'd be perfect for that.

I would concur with Steve Latchers remark. It would work perfectly for what you want to do.

When you start the GPS unit, and it syncs up with the satellites, you then press the pushpin icon which lets you set your current position as a waypoint that you name. In the nav screen, you can then select this as a goal, and the unit will keep track of your current position in relation to this waypoint that you set, with bearings and distance (as the crow flies) information. It will also paint your track on the screen which you can record.

The Geode will be better for hikers when it's out since you'll be able to download topo maps to the Visor which will especially help those that don't want to just back-track on their return hike.

In most situations, the value of topos can not be overstated. However, no matter what, you will probably need to carry good old paper (or treated paper) topos. After all, what would you do if you break your Visor's screen, and can't access your electronic map? For this reason I'd suggest that the Geode is preferable, but the HandyGPS is still an OK investment for hiking.

However, the best is still a stand-alone weatherized GPS unit. You need GPS most when the clouds descend, and you can't make out landmarks. A device that tolerates rain, while remaining operable, is the ideal. This latter point is a problem with the Visor as there are no weatherproof carriers that accomodate oversize modules and allow you to operate the Visor at the same time.

agree totally - I have the Garmin GPS III+ as well as the Nexian HandyGPS. The Nexian does not compare. I'll say that again - the Nexian does not compare. It is, however, one third the price (excluding Visor...). Intrigued by the Geode when that comes out...

Care to give us a short synopsis on the differences? I am curious more than anything else.

Why not just use an existing case like one from Rhinoskin, and then place that inside of a loose fitting plastic ziplog bag? Ruggedized, weatherproof, and you can operate the Visor at the same time, even in the rain.

or try the aquapac...

Ziploc bags are neither rugged nor sufficiently weatherproof. Sadly, this based on multiple instances of bag failure while in the field . . .

Aquapac doesn't look like it will contain a Visor with GPS module. But, if someone else wants to try it, and report back to us . . . Well. More power to 'em!

This doesn't mean that I won't be taking my Visor along. It just means that it will be safely ensconced in my backpack, inside a Rhinopack, and inside a ziplock bag. Location in pack? Top of main compartment, and up against my the back. That should protect it from getting banged around, and out of any potential in pack puddles.

yucca, aquapacs come in several sizes. the ones made for palms/visors are obviously too small for a visor AND a module that sticks out, like the handygps, but the aquapacs for things like cameras are the perfect size.

and if you want ultimate protection, just get a large otterbox.

I guess I shoudl re-phrase my statements/question. I don't want a GPS that is primarily highway/road based navigation. I want something that has a good feel for a hiker, not an adaptation of the HandyGPS.

I don't want to cough up the change for the Garmin's, but I might if a nice Visor GPS doesn't come my way soon.

The only GPS Springboard module that looks like it will meet your needs is the Geode. However, I have to question if topos with a scale suitable for hiking will actually be available. If such topos are not available for the Geode, then any GPS Springboard that outputs appropriate coordiantes for use on a conventional paper topo will do.

BTW, some of the larger aquapacs do indeed look like they would get the job done (the medium size case for GPS units looks promising - http://www.aquapac.net/homeframe.html ). Has anyone actually tried one? How well does graffiti work through one of these? Is it similar to the Aquaman PP10? If so, then James' review of the PP10 answers the question re: graffiti . . .

Certainly. Let's start with the physical stuff first:

1. The garmin can be used with one hand - all buttons, no stylus
2. The garmin is truly waterproof - no need for aquapacks, etc.
3. You can hang it around your neck

Then there's the maps. Granted, you need to pay Garmin an outrageous sum for these things. I bought the US Roads and Recreation, the US Topo and the UK R&R, coming to a total of around $500, so we're not talking cheap! The maps are, however, just totally superior. What I should do is stick a few pictures up for comparison, but I haven't done that yet. The best bit is that the maps can be used on the PC to keep track of waypoints and so forth.

Then there's the fact that the Garmin has a serial output which can be used to drive PC-based mapping programs, such as Streets and Trips 2000, giving you really useful navigational stuff for your car.

Finally, there's the display options. For some reason, the HandyGPS uses what appear to be two programs to provide its functionality - one for GPS and one for mapping. This makes it hard to get an all-inclusive display as you're on the move. Not so with the Garmin - you even get to choose which fields you can see.

Of course, you've got to bear in mind that my total investment in Garmin to date is around $1000, compared to $150 for the handyGPS.

Hope this helps

One more thing - accuracy. I just did an empircal test around the parking lots here. The Garmin found way more satellites (like about 8) and also gives its view on its own accuracy - I got to 18ft in one case. The location displayed by each device was slightly different - the handyGPS was between 15 and 30 seconds different from the Garmin in both Long and Lat. I tend to trust the Garmin more.

Question

Adam,
I have a question about your comparison of a standalone GPS (Garmin GPS III+) vs. the HandyGPS. I just received my HandyGPS a few days ago and have started to try it out. The very first try in fact was a trip to Wilmington, NC, from Chapel Hill this weekend. Besides some other problems related to battery power in the Visor, I experienced only a few minutes when I had satellite "lock" and could observe my position. Now I am a total GPS newbe so I was just holding the whole unit in my lap while my wife was driving, i.e. it was no where near the windshield and we have a metal topped vehicle. With your apparent experience is this the kind of signal I can expect from any GPS unit? If not, is the HandyGPS just not powerful enough (this does not really make sense to me because I thought that it was just receiving the satellite signals)? I guess the bottom line question is will I get better signal and route coverage with a separate GPS attached with a serial cable?

What I really want to do is take the unit on long mountain bike trips, so signal in a car is not crucial, but the lack of performance disturbed me. I.E. how will the signal be with trees around?

On a separate note, regarding the Geode discussion above, I am not sure how many of you are involved in their beta test, but after looking at their beta software and the HandyGPS software, I question when the Geode will actually be ready to ship. There are a lot of features that were missing (relative to what Nexian has - which I will also say is not THAT much) in the version I tested, and there are not that many more days before the "end of summer" release date. I figure even if it does make it out in the next 3 months don't hold your breath for topo maps. There seems to be a lot of fundamental functionality missing to be thinking about perks like topo maps.

Thanks for any light you can shed on these questions,
Ryan

Ryan,

First, an external antenna on a car will unequivocaly work better than the HandyGPS inside a car. The Garmin allows you to plug in an external antenna, but my car already has a navigation system and external GPS antenna, so I haven't tried it.

I guess that, like you, I am confused by the handyGPS performance - it is, as you say, 'just' a receiver, but it seems to have far more trouble receiving than either of the other two GPS units I have (the car and the Garmin).

I'm also on the Geode test - hard to know what to expect yet, of course!

So, bottom line, if you know you want to use a GPS system for in-car navigation, get one which can take an external, or at least dash-mounted, antenna, and make sure it (or your PC) can do routing - preferably dynamic. It all comes to down to how much you pay in the end, I guess.

Thanks for the info Adam. I do appreciate your experienced opinion. I have done some more testing with the HandyGPS and I am going to contact Nexian today about getting a replacement. I can stand out in my parking lot, with a very clear view of the sky and the tracking will come in and out, just standing there! I also took it on a walk around the neighborhood and with the unit in my pocket it NEVER tracked my position (~ 3 mile walk). So based on the generally okay performance that others seem to be getting I am assuming that mine is one of the units affected by the faulty components (or whatever their problem was). If I find out this is status-quo operation for the HandyGPS than I am going to return it, and probably just wait for something better to show up.
