ELECTRONIC MARINE BAROMETER (Weems & Plath #4003)

This electronic marine barometer is specifically designed 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 for 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.
