For me things are simply….results matter, and results in my field of work means summits. There is no doubt that The Altitude Centre can give you a critical head start in the acclimatisation game for expeditions. Having seen the system work this last expedition to Manaslu (world’s 8th highest mountain), I now see the benefits of training with a hypoxic generator. The advantages for High Altitude Climbing is obvious, I will be using the system before leaving for any expedition in future. Put simply….IT WORKS. There is no doubt that the Altitude Centre can give you a critical head start in the acclimatisation game for expeditions. People don’t go to sea level to 5000m in 3 days but with an Altitude Centre hypoxic generator that’s exactly what we saw on our Manaslu expedition this year. The chance of Summit success can be improved on certain mountains by using the Altitude Centre. I recommend it to anyone thinking of climbing a high altitude mountain.
