I Have to say i am a BIG fan of the Crusader cup, canteen, and cooker combo.
that old phrase is whistling through the air again.......what was it.....
"Horses for courses"
if you like the 58 bottle and cup, you'll have a Crusader cup canteen(metal mug).
the cooker is the ideal partner to it, tough and simple.
before we moan about the heat, you have to look at it's design.....
it is designed to make drinks or heat boil in the bag rations(that don't need thorough cooking).
it is not designed for fully cooked meals that require simmering or more than 5 minutes cooking.
i use it for making hot drinks, from being in my army pouch i usually have a hot drink and packed away again within about five minutes!
but that's what it's designed for!
it is not a system i would use up a mountain or for normal camping as it isn't up to the job. my MSR petrol stove steps in here or my trangia.
i take it with me whilst teaching bushcraft just because it's really hand first thing in the morning whilst in bed, or in torrential rain when the campfire has died.
i use a mini coke can meths stove design, it is the same height as the lip of the burner dish, it's quite adequate.
my system is probably more efficient as i have made a metal lid for my mug, also having everything black(non-stick) everything heats up alot quicker.
another advantage to the system is it is not fuel specific.
i use as i said a meths stove but because of the crucible(burner cup),
i could also use just meths on it's own,
Hexamine
Fire gell
or simular burnables (glue, wax, parafin, petrol, oil, vodka or whatever....)
try doing that with a hexi cooker
for me it comes down to these few things:
it's tough, non-stick, easy to use, multitasking, little if any risk of fire spreading, compact, you can use a messtin or other pans on it(with less effect), it fits into my pouch and makes a neat package with the rest of the set, you won't mark the ground, good wind resistance, far safer to use the flames are centralised as oposed to a hexi cooker.
(
and it's all black and looks cool!
)
i love it, but i understand why others don't, same with anything know it's limitations and you woun't go wrong!
