The Polaris at Altitude
After reading a few dozen reviews, I decided, rather than hunting down parts to fix my Svea123 and spend $90+, I'd give the Polaris system a try. I found a smokin' deal for less than the Svea kit and put the system to the test. I hiked up to a nearby peak at 13600', screwed on the isobutane cartridge, filled the 1 ltr pot and started the timer. At that altitude on a clear day, you can expect water to boil at 187⁰F. Water was roiling in 1m26s. Next, I twisted on the neat little adapter and tested cold water with a 1# canister of straight propane--1m38s. The system is incredibly efficient, and I suspect it consumes much less fuel by weight, even considering the canister tares. Someone with more patience than I would have to do that test. In short, I LOVE IT!!
