# Thread: Core vs. Vector - vertical speed

1. ## Core vs. Vector - vertical speed

Hello everybody,

I would appreciate your help - i would like to buy a watch for my husband's birthday and i am deciding between core and vector. As far as the design i prefer the CORE, cause i thing he won't be wearing it only in outdoors. But the thing is that it doesn't have the vertical speed function, apparently so i am wodering whether CORE has something to compensate it, e.g. if the logbook shows you the speed in real time as you are going up/down the mountain? I think this function is very useful

BTW are there any other reason why should i choose vector over core or vice versa?

Thank you very much

The logbook in the Core does tell you the vertical speed in meters or feet per minute. You can't see that in real time though, as far as I know; it's only after saving the log.

I was also choosing between a Vector and a Core when I got my Core. The reasons why I chose Core were the alti/baro lock, sunrise/sunset listings and the baro graph function.

The Core is way more advanced than the Vector in every way. The Core has many more features, better display and updated hard and software. The Vector is a solid watch but is a dinosaur compared to the Core.

Eh?

Alti/Baro lock:

The altimeter is a barometric one so it measures altitude and altitude differences by means of pressure changes. This have the disadvantage that changes in weather (air pressure) will affect the altitude value, this is known as altitude drift. The same is also true when it comes to the barometer and its weather readings. Changes in altitude will affect the weather reading (the weather trend). So this means if you are moving up pressure will go down and the watch will think the weather are getting bad, or the other way around when moving down that the weather is improving. Or if there is weather changes going on the watch might think your altitude is changing when it is not.

Suunto have solved, to some extent this issue by incorporating a Alti/Baro lock function. The way it works is that the Core has different profiles. You use the altimeter profile when you want to record the altitude and are moving up or down. The watch will then interpret any pressure changes as altitude change rather then weather change. Or if you are stationary you use the barometer profile and any changes in pressure are interpreted as weather change rather then altitude change. There is also a automatic profile where the watch by itself detects if you start moving upwards/downwards and automatically change between the altimeter and barometer profile.

This do not solve the problem entirely tough because if you are moving in altitude and weather is changing then there will of course be some altimeter drift. So it is always best to write down some known altitude reference points prior to leaving for the trip. For instance topo maps or Google Earth can be used. Then during your trip if you see at a known reference point that your watch are showing a value that is a little off then you just re-calibrate it so that it will be on track again.

Greetings to our brethren country.

So, what you are saying is I should manually change between alti and baro from whether I'll be stationary or not? Cause I have it in auto now, and that is whats giving me trouble.

Was thinking maybe if I could set a sea level reference that might help the computer, as opposed to any alti reference?
Dunno why I think so, it just seems plausible. I.e. go to lowest point, sea level and have a base reference.

situation: I'm on a hike in the mountians so I will use the altimeter, but I also want to be updated on the weather! Is this possible, or not! It seems hard to believe that the watch can give accurate readings about pressure when you're also moving higher or lower in the mountians!
