/ Altimeter queries - barometric vs GPS
Thanks in advance!
Yeah those pesky atoms are nightmare out on the hill. ;-)
have a look at the suunto ambit.
its altimeter is baro based but gps fluenced when you turn the gps function on. apparently.
its quite smart and can sort of tell differences between height gain pressure changes. and it gives altitudinal changes in units of 3m (plus storm warnings and all that jazz).
got a HR monitor too.
Not quite related...just got a foretrex 401. Wrist GPS with altimeter and electronic compass. Has options to display vertical ascent/descent m/min, barometer, amb pressure, sunrise, sunset, and a tonne of other things. It has some wireless ability and I here there's a cadence sensor addon, not sure about HR. Oh, and can show a graph of your change in vertical, either over time or distance.
Pretty popular in military circles it seems. Got it it new on eBay for a very pleasing price :)
The foretrex 401 is not really a watch though.... How big are your arms?
Fair call....It sure aint small.
I personally prefer to have a somewhat imprecise tool, but that doesn't get mad when the weather changes.
If you have a lot of experience with them, barometric altimeters are fine I suppose.
The best elevation tool is a map and when combined with the GS its very powerful. most gps' will give you data on your progress. HR maybe a limit, Iíve never looked for one
the map is a good weather indicator too - when the winds picking up it flaps around more and when its snowing it goes white </joke
The old Suunto X6 had the best altimeter so far.
From reading through the thread it sounds like the GPS function of these watches can be turned off, leaving just the barometric altimeter. Is that right, or have I misunderstood it? Is it only some models that allow that?
If the GPS can be turned off to save batteries when not needed, but when it is needed it provides a useful grid reference, then I might start thinking more seriously about them! I only really want an altimeter, but the GPS might be a nice-to-have sometimes in a whiteout on the plateu... I'm not really interested in anything else like HR monitors and compasses - any recommendations that would fit my description? Thanks!
Have a look at the suunto ambit. You can turn on/ off the GPS option and it does everything it says brilliantly- you need a reasonably sized wrist for it to look good tho.
GPS and map is probably the right answer since there are fewer unpredictable variables.
GPS altitude is subject to considerable problems. It is highly dependent upon the amount of sky you can see and the position of the satellites in the sky. Some devices give you information that might help you in making an assessment about this but it's a bit sketchy. It will be affected by constellation reconfiguration much more than a GPS position.
Barometric is clearly subject to the atmospheric changes detailed above.
On a ridge on a nice day, both will probably give excellent service with proper service (settings/batteries) and intelligent interpretation.
Bad stuff doesn't usually happen when the sun is shining.
Have a look at the Casio Pro Trek.
They are solar powered also.
Tbh ,I now question the need for even having these gimmicky watches.
Shiny toy syndrome.
Still going to get a pro trek though as it has the added bonus of being an everyday watch and not an overly fussy Star Trek type thing
Obviously a barometric one is ethically purer.
The Baro altimeter displays pressure when stationary or nearly so and height when moving.
It will give a grid ref for a number of different systems, UK, UTM etc.
Compass is significantly better than all the previous ones I have seen, you do not have to have it horizontal.
Garmin Fenix will be better for location / hiking than Suunto.
I got the Suunto for running as well as hiking, it is much better than the Garmin at this.
Brilliant.. nearly choked on my apple :o)

What is your impression of battery life of a GPS ?
I had mine on when I was driving around on holiday in the car, I forgot to switch it off one night and the next day, it was still working fine. I use rechargable batteries and I have never been able to walk long enough in a day to run out of power on the GPS starting with charged batteries.

But that is a weather indicator, not a weather forecaster.
Have a look at the Garmin Forerunner 410 (I have the older 405 version) good HR monitor, plus GPS tracking so will give you altitute too. baterry life is about 8 hours of GPS tracking, about a week whilst used just as a watch
