whats up guys i was just wondering about bottle heaters. how long does it usally take to get the bottle up to pressure.when it reach's its optimal temp how long will the bottle stay at optimal temp for on say a 60 degree day?

 

getting up to temp depends on how much n2o is in the tank. More n2o, takes longer. ambient temps are an obvious variable.
keeping it at temp depends on how much/often you're shooting. As you shoot, it 1) reduces the amount in the tank and 2) chills the tank because of the moving gas.

Doesn't help much, does it.
