GPS for training
I believe this has been covered before, but just a quick note saying that I've
been using my GPS as a hiking odometer and I like it. I can go off trail, up and down steep hills taking whatever sized step suits the terrain and not worry about it throwing my distance off. Can also be used biking, skiing, blading, paddling, etc. I put it in a fanny pack and forget about it, works great. Can also be used for Geocache hunting! (why I have it in the first place). That's all. jw milwaukee |

which GPS unit do you use? Does it take HR input too? Does it upload to a
computer for storage and analysis? Does it overlay your track on a map? Bob "J999w" wrote in message ...

Garmin eTrex ... bottom of the barrel, dirt cheap, basic unit. Doesn't read
palms or read biorhythms. I've seen it as low as $49.95 but can be had right now for $83 according to Froogle. jw |

You could immediately see when you got in/out of wind, current, deep water, etc. I did notice that the elevation differed by about 75-80ft paddling across a lake:-) Probably not going to rely on it to map the birkie...

Which is why you'd really want a GPS with built-in barometer if you do any kind of activity where a 3D track log is useful. All the higher-end Garmins (with an S for Sensor suffix) have this. Using this together with OziExplorer allows me to get really nice elevation plots from trips I make. Terje PS. The real use for a GPS is Degree Confluencing, not that upstart GeoCaching stuff. :-) http://www.confluence.org/ Terje (Scandinavian regional coordinator) -- - "almost all programming can be viewed as an exercise in caching" |

Marsh New Brighton, MN great test on a lake! no wondering if you 'think it is level.' i've always been suspicious of the altitude feature of my garmont/timex unit. people who really care about elevation use an altimeter. some units come with a 'barometric' altimeter built in. however, on one circuit hike of afton state park, a unit with an altimeter placed the parking lot at some 50(?) feet higher than when we had started. we wondered if the approaching storm was enough to lower the pressure that much . . . jim -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

I've raced on ski courses like that. The finish is right beside the start, but you feel like you have done twice as much climbing as you did downhills. Scott |

Barometric pressure varies about .1" per 100ft (Not exact, but close enough for eyeballing stuff). A fast moving front can raise or lower the barometric pressure by several tenths in a very short time period. I'm still curious about the update period for the barometric units. I wonder if they can be accurate enough to handle the short, quick transitions at somewhere like the Birkie at ski speeds. Hiking, they certainly should. In any case, they are all cool toys. I'm still not sure I'll take it to the BWCA next week, though. Marsh |

The barometer is used together with the GPS signals to compute a new 3D position every second, but as you note, it is possible that a very short/quick dump might be skipped entirely. At the same time as the barometer is used for short-term altitude differences, the GPS altitude is used to calibrate the barometer, with a time constant of about 3 hours.

All you US GPS'ers out there should check out endlesspursuit.com and
topofusion.com. Pretty incredible stuff - calculates everything you could possibly be interested even average power output, total calories burned, and you can get some mind-blowing maps. Endlesspursuit is focused more on athletic accomplishments, while topofusion is a little more map-oriented with some incredible 3-d features that I used for mapping some trails that we built this summer. I wore my GPS in a few races this year and posted them on the web site. Check out the Owl Creek Chase from Snowmass to Aspen: Go to www.endlesspursuit.com Select "Community", then "Search for a trek". enter Owl Creek Chase in the text field, "natrons" in the author field. Once you get there, click on analysis and you can see all the info they calculate. 1450 calories in 1:10. No wonder I'm hungry all the time. -Nathan "Terje Mathisen" wrote in message ...
