Thanks, but me, and anyone I ski with will be turning their phones off each and every time before heading off piste. As I said - turning your phone off simply removes any possibility off interference - it costs nothing and removes a degree of uncertainty however slight it may be. Additonally when time is at an absolute premium in a rescue situation fishing a phone out your pocket, fumbling for the off switch in gloves and turning it off (providing you actually remember to do so under duress) before starting the primary search is an unnecassary, time consuming task that wastes someones breathing time under the snow!

Some ok runs in La Rosiere, a nice long black off the right of the main resort run - the snowpark isn't up to much at all and it can get VERY windy - not only gets very cold when the wind kicks up but most of the snow simply blows away!

Last time I flew to Grenoble with skis they arrived with a big motorised trolley thing and just piled the skis up next to the carousel.

Looked decent enough to me, you've certainly got the basics of carving down ok there - you could probably commit to a bit more lean angle.

Try to transition a bit faster, rise out of previous carve more positively, pressure the edge of that outside ski early, commit to more lean angle sooner in the next turn and get cranked over a bit more at the apex of the turn and let the knees bend as you soak up the G's - then shift that weight over dynamically while rising positively into the next turn and repeat!

I did notice once or twice you lost a tiny bit of balance and momentarily turned your shoulders up the slope a smidge, thats something you don't wanna be doing.

Basically get the transition a bit snappier, more commitment to lean angle and never turn your shoulders up the hill to correct a wobble.

Keep it up fella!

People have mentioned raising the heel to allow some application of forward pressure, that will help to some degree but a more central binding position would help a lot too. What about moving the bindings to a more central position where applying forward pressure is less of an issue?

A fully symetrical park ski centrally mounted would be a lot easier for you to ski on - as your centre of gravity is already over the middle of the ski there would be less need to be pressuring the fronts of your boots - with a little heel lift you'd be able to achieve a relaxed knees bent stance and wouldn't have to worry about keeping your weight over the skis point of balance as your centre of gravity would already be over the POB without having to press forward into the boot at all.

A good tech who has tuned race skis could do a proper POB central mounting on a pair of park skis that would help you out a lot - that combined with a modest heel lift and you should be fine. I'd be a matter of finding how far back from central you would need to mount up to accommodate the heel lift you need for a comfortable stance - a heel lift will enable a better stance but will shift your weight forward a bit - you would need to mount slightly behind centre to allow for this - a good tech should be able to figure out exactly how far back would be right if you show him how much heel lift you're working with.

Essentially the central mounting would remove the need to get your weight forward - the heel lift would simply facilitate a comfortable skiing stance. You'd be 100% able to carve perfect arcs with really good style.

However it should be noted that the mobile phone should be OFF until needed. If you have a mobile and beacon that are both on at the same time the mobile interferes with the flux lines the beacon sends out and makes pinpointing you almost impossible.

Before heading off piste everyone in the part should not only check their beacon is transmitting - but also that their mobile phones are switched off too. Otherwsie you might as well not be wearing the beacon!

Actually, there's no evidence that a victim's mobile phone interferes with a searchers transceiver.

"All current avalanche beacons suffer from interference from portable telephones but this varies according to the mobile phone and beacon (PH found the same in tests). The interference is generally in a range of 10-50cm but sometimes as far as several meters. Analogue beacons can pick up phantom beeps and the LEDS can flash randomly. Digital beacons emit random beeps and the direction and distance readings are unstable. It is important to note that a transmitting beacon is unaffected so a mobile phone on a victim should not cause any problems.

It is important to note that when members of the rescue services make a search with an avalanche beacon they ask for what is called “radio silence”, that is all electrical equipment in the search area must be turned off.

Some advice from Patrollersupply.com...

"** Mobile phones should be switched off when searching **
Mobile phones can seriously disrupt the ability of an avalanche beacon
to receive a transmitting beacon's signal"

Something from Pieps' own website...

"Due to their nature, ALL of beacons are very sensitive against electrical and magnetical interference.
If a Ferrite-antenna is exposed to the field of an magnet (magnet of a speaker of a radio equipment in extremely close proximity, less than 5 cm), not only the signal strength (send AND receive) can be influenced significantly. Also the magnetic property of the Ferrite material is changed, due to the magnetic remanence – this can last a couple of minutes (up to 15 minutes)."

Personally I don't need an exhuastive study to prove the extent of inteference between each model of mobile and each model of beacon - its a lot safer to simply switch the mobile off when you leave the piste - who wants to field phonecalls while skiing powder anyway?

Hang on!

I've always been told that when carving on-piste, the majority of one's weight should be on the outside ski. Basically the inside ski is there primarily for balance - it should be on edge with a little pressure applied so it tracks in line with the ouside ski but by no means should you look to balance your weight evenly between both skis - the lion's share of edge pressure should be on the outside ski with just enough pressure on the inside ski to carve a matching arc. Only when carving turns in powder do you need to make more of an effore to distribute weight evenly.

Is this correct?
