The Blue Hill UL series was originally designed to cook using Sterno or similar fuels while ice fishing but there are many more applications such as fishing, hiking, backpacking, bushcraft. Any outdoor activity where a cup of coffee or hot meal is desired. The options are only limited by the imagination.
The Blue Hill UL 2 stove ring can be used with tuna, cat food, and soup cans approx 3.25" in diameter along with small hobo stoves, small rocket stoves, etc. It can also be used on the Trangia Alcohol Stove when used upside down resting it on the threads. These options allow for the use of virtually any type of fuel.
