So regarding the map, I am being very serious. I don't ski off piste with one.
However I suspect my definition of off piste is different to you guys who carry a map! Mine will be (or has been so far) lift served, where I am within 5-30mins ski from a lift or piste. If I have gone further afield I have taken a guide. |
30-minutes is a relatively long distance for lift served off-piste, so I would very definitely suggest taking a map. |
Not if there is only one way out via a road, which you will hit whatever way you go down.....

One interesting point the bloke who sold me my new snowpulse made is that if you are competely buried with that deployed -it is partially permeable and filled with compressed air - effectively increasing your air space by 150L. Whether this is proven is another matter.

Interesting... I wonder if there might be a way, in the even of a burial, to use the air in an airbag to increase how much air you have to breath before it gets too CO2 tainted? What gas do they use in the airbags? |
compressed air.

For purposes of establishing exact position in an emergency, a map is highly recommended.

I think the ABS model uses nitrogen.

Well that would make sense 
I was sure I read somewhere something about one of the systems using compressed CO2?

clarky999, the snowpulse is compressed air and I believe it does allow some diffusion of air out and Co2 in. I believe the ABS is nitrogen.
That and the lack of pyrotechnic charge is one reason I chose snowpulse.

Abs uses compressed nitrogen. The reasoning behind this and the pyrotechnics is that it minimises the possibility of the line freezing up. As I understand it at least. Physics isn't my strong suit.

There should be no moisture in the Snowpulse system because they use dry air.

kitenski, no wish to be patronising but:
What if you break a binding and have to walk out? 5 minutes skiing could take hours to walk in deep snow.
What if you have to give a position in an emergency?
What if you just get it wrong and have to figure-out a new route?
What if there is indeed a road at the bottom of the route, but some lines would take you over a cliff in bad weather?
At about a fiver, a map isn't much of an investment. I'm a map geek anyway and I love poring over them in the evenings.

stevomcd, yeh interesting points and you (+others) have made me think, any suggested places to get them from? need one for Zinal PDQ and one for Stuben not so PDQ....
cheers,

And love to help out and answer questions and of course, read each other's snow reports.

You can always pick them up in resort. Go for the best 1:25,000 one you can find.

Sounds like you want the Anniviers freeride map ?
http://www.freeride-map.com/index.php?lid=2&cid=200
Thought the swiss topo is just as good. (get the S, ski tourers, variant).
Maps are essential - they help you find the best skiing and snow

Local shop probably, maybe in Grimentz or if you're driving there's a ski touring shop in Sion called Snow and Rock that will definitely have them, I can give you a link on google maps if you want. Certainly there were a few shops in Nendaz that had them for various local areas. Get the blue one rather than the yellow one and it'll have the ski tours marked rather than summer paths. In the UK Stanfords are normally pretty good at getting hold of them.

Me too, also a good way to work out how to access that line you spotted from across the valley.

kitenski, there is definitely a shop on the main street in Zinal which sells the skiing maps
online, themapshop.co.uk has pretty much everything you can think of

Only thing about the skitour map is it's 1:50000, there is (obv) quite a bit more detail on the 1:25000.
kitenski, not like you won't be with people with maps.

Personal preference but in busy areas I prefer 1:50000 as I find the map less cluttered with small objects e.g. boulders that may or may not be covered in snow. I also find 20 (or 25, Italy I'm looking at you) m contours can be more misleading on a 1:25000 map, this might just be me though.
|
|

and then you get a map that shows both France & Italy (eg. Mont Blanc) and the contour interval changes at the border on the same map !

I like the freeride maps, the swiss ones are based on the 1:25000 SwissTopos.
You should be able to get them in the resort in a good gear shop or maybe in a newsagent or bookshop. You can order them online but they take a few days to get to the UK.
The ski tour maps are also a good idea, but as others have said they are only available in the 1:50000 scale. For planning a trip this is fine, but for tricky route finding and locating yourself if you get lost the 1:25000 is better for me.
Another thing to look out for is that the standard SwissTopo maps are pretty small if you are used to British OS or French IGN maps. However, for some areas they publish composite maps which cover a much bigger area. Not sure about the Anniviers, but they certainly do one for Zermatt for example.
