The electronic marine barometer is designed specifically for the mariner. Not only does it show current pressure on the large display, it also displays historical information on a much more expanded scale than most electronic barometers which makes it perfect in a situation where there is a change of watch and the new person on duty can see the changes that have occurred over the last 48 hours in 30 minute increments
