Do you allow 4 peak altitude altimeters in one rocket? The readings of the 4 altimeters will be estimated to get the average altitude. Then the readings will have +-10 ft margin of error. Or how about one PA altimeter and another logging altimeter? And will be estimated as well. And how about manual calculation?
I asked these questions because my country does not have any available altimeters in store. I do not want to buy online (too much hassle)
Cheers

A water rocket is a type of model rocket using water as its reaction mass. The pressure vessel (the engine of the rocket) is constructed from thin plastic or other non metallic materials (usually a used plastic soft drink bottle) weighing 1,500 grams or less. The water is forced out by compressed air. It is an example of Newton's third law of motion.
