riverridge2198344's Bio

I like to be outside----mountains, deserts, rivers.

Trying to enjoy the Rockies and get in some exotic mountains every now and then.

So far: two long trips to Nepal, one to Peru, and one to Argentina since 2005.

The best 4-Season canister stove!
5 5

Familiarity: I've used it several times

We have been doing some winter testing of the Vega. Below 30 degrees F, you need to invert the gas canister for great performance (4-season-mode). At 4 degrees F. it boiled a pint of water in 2 minutes 30 seconds.

At 17 degrees F. with no wind, I tested the Vega in 4-season mode with a nearly empty 4 oz. Optimus fuel canister.
Boil time of 1 pint of water was 2 minute 42 seconds.

I then used the same canister on a conventional up-right canister stove (Optimus Crux). The flame barely burned and when it went out 5 minutes later, the water was only 100 degrees F..

Groups I've been with have pumped around 100 gallons of back country water through my Vario in the last year. For clean water we've used the Faster Flow option and can pump at 3 quarts a minute-----I've actually timed pumping a quart at 17 seconds.

For dirty water we use mostly the longer life setting and pumping slows to about 2 qts a minute. I have clogged the ceramic filter within 3 quarts in very dirty irrigation ditch water in Peru-----but it cleans up quickly.

I love the Vario, but you have to read the instructions and plan on some maintainance, if you are going to pump a lot of water. I recommend it for group trips, and I still day hike with the slower, but smaller and lighter, Katadyn Hiker------now that filter is idiot-proof.

The EPA (Enviromental Protective Agency) required Katadyn to submit to some very tough tests at University of Arizona Dept. of Microbiology before they would issue a registration number for Micropur in 2002.

Every word on the package was negotiated with and eventually approved by the EPA.

The news for those that don't like to wait 4 hours is: Micropur uses the most effective chemical registered by the EPA---Chlorine Dioxide at 4 PPM(parts per million) for killing all disease causing micro-organisms in water. In the EPA's cold dirty water test it took Micropur 4 hours to kill Cryptosporium Protozoa Cysts (eggs).

Cryptosporidium causes a two week bout of diarhea and other ugly symptoms, and is just as common as Giardia in water worldwide. A 1992 CDC (Center for Disease Control) study found Cryptosporidium, or Giardia, or both, in 97% of the streams sampled in the U.S.

If you are just worried about Protozoa and bacteria in your backcountry water: use any of the fine micro-filters from Katadyn or MSR to filter those out-----and have cold fresh, non-chemical water immediately.

I use Micropur as a back-up in case I lose,break or clog my microfilter. However, in trips to Nepal & S. America my group first pumped the water through a Katadyn Microfilter to remove the hard to kill with chemicals Protozoa (and bacteria as well): then added a single tablet of Micropur to each Liter of Water.

Virus that may cause incurable and deadly types of hepatitis are common in polluted water in those continents. Virus are much more susceptible to chemicals, and the EPA testing shows that even in cold dirty water all the virus are killed within 15 minutes: 1 tablet of Micropur per 1 Liter of water.

If in doubt: microfilter first, then add Micropur: wait 15 minutes and drink clear, safe, good-tasting water.
