The extra ounces and annoying Dualist windscreen attachment design (as tested) don’t make up for the impressive performance of the GSI Pinnacle Canister stove when compared to the simplicity and stand-alone performance of the Soto Windmaster or Kovea Power Nano.
The GSI Pinnacle Canister stove is very efficient and boils water at the top end of the category when the Dualist windscreen is included. It’s faster than the Soto Windmaster. Without the companion windscreen, the Pinnacle Canister is an ordinary, mid-level performer.
Both the stove and windscreen components fit neatly into the GSI Pinnacle Dualist integrated cooking system for a complete backcountry kitchen.
The GSI Pinnacle Canister stove boiled two cups of cold tap water ten times at an average of 2:21 in sunny, calm conditions at 6,600 feet. This is faster than the Soto Windmaster. This test was split between Jetboil’s Jetpower fuel and MSR’s IsoPro.
The stove averaged 3:10 to boil two cups of cold tap water in consistent winds of 14.5 mph with frequent gusts above 25 mph.
Users of the Pinnacle Canister stove can expect to boil an average of 14 two-cup pots of cold water on 3.5 ounces of fuel. The efficiency test used Jetboil’s Jetpower.
The stove simmers fairly well for an upright and allowed me to cook a number of simple backpacking meals on various fuel types like soups and pastas in conjunction with GSI’s Pinnacle Dualist pot. Drawback: the circumference of the windscreen limits use of some larger, third-party pots.
Alone, the GSI Pinnacle Canister stove is 2.4 ounces. The Pinnacle windscreen adds 2.7 ounces for a total of 5.1 ounces. Total weight makes it heavier than the MSR Superfly.
