Geocaching/flying

Any pilot who's also into ground geocaching? I'm thinking about buying a new
GPS receiver to use for that purpose, but also wonder if these hikers' GPSes
can also be used for aviation, perhaps as a backup navigation instrument. (I
use an older Trimble for flying.)

I use a Magellan 330 Map gps for hiking (at OSH), driving and flying. Get
the mapping software and the PC connection cable to upload and download
waypoints, tracks and routes. It has airports in its database but I put the
local ones in by their identifiers. I also put in the tall antennas in the
area as obstructions. It works well for my use. (YMMV!)

I just bought a panel mount Trimble from eBay, should arrive today. I'm not
sure how soon I'll get that installed in my plane.

Henry,

I am not into Geocaching. However, your could Geocache with an aviation GPS
or you could navigate your airplane with a non-aviation GPS. It all depends
on what compromises you want to make between size, price, and aviation
functions.

Especially for VFR use, a non-aviation GPS makes a great tool. For all
practical purposes, you will have to load aviation waypoints as user
waypoints. Many receivers will hold 1000 points, some will hold 500 and
some will hole more. You can upload get these coordinates from a source
such as www.navaid.com and use a free program such as G7toWin to load them.

I personally prefer Garmin receivers. I especially like the ability to edit
the route directly on the map by essentially dragging and dropping the route
line. I also think the best navigation interface is the map display for
situational awareness and the data fields for precision. The Magellan units
only offer two data fields.

Some of the units that you might start looking with are the Garmin GPSMap76,
60C, 76C, 176, or 276.

This is what I did, to save money by buying a Garmin III+ instead of
the pilot version. The "datachunk" cost me $4.

A while ago I was trying to find a waypoint in rough air, and I
decided that I just plain had too many waypoints for my own good. So I
downloaded them to my computer (I use EasyGPS software) and saved the
file as allwaypoints. Then I deleted those in Massachusetts and any
over 100 miles away, named the result localwaypoints, and uploaded the
shorter file to my Garmin. This has been a great improvement.

I don't find the Garmin very intuitive. It's a great help to be able
to massage the data on the computer.

I have a Magellan 315 with aviation database that I use for flying and
geocaching. Works well for both.

I use a mid-level Garmin. Haven't used it myself for air navigation yet,
but I've had my wife take it along and do things like turn it on to see if
it disrupts anything (nope) and see how well it works.

The short answer is, it works great except the altitude data can be pretty
erratic. Other models may have better alt determination, but I sure
wouldn't trust the altitude data on them.

Beyond that, it's great. We carry it and a digital camera everywhere we fly
now.

Then you should know about oziphototool-- works with oziexplorer to
automatically mark on a map where your pictures were taken, by examining the
timestamps of your pictures and the track from your gps!

That's very interesting! Thanks.

We do too. Have a camera case that the camera and GPS both fit in
nicely. Our camera has a 10x optical zoom which will take some decent
pics from the air. http://pad39a.com/gene/house.html

I had an Airmap 100 I used in my airplane, but I bought a Garmin Geko 201
because it has much better track logging capability. Since I have an IFR
panel GPS (KLN-94), I don't use the Geko for navigation. But when I fly IFR
IMC I set it to nav to some airport anyway. The nav features are quite
rudimentary (e.g. just heading, bearing, speed, distance), but in a complete
electrical failure it might be helpful.

And the Geko works fine for geocaching. It doesn't have any basemap but
that's just not really needed for geocaching. I did learn pretty early on
that a good pocket compass is a very helpful supplement, though!
