ABSTRACT:
A pocket tide calculator is described which predicts tide times and moon phases in a visual display which gives the semi-diurnal tide times in any given day of the month and can be readily set for the following month. This device automatically leaves out the high or low tide which is alternately missing every 7.5 days. This invention incorporates a compressed time scale when compared with a normal 24-hour clock face which enables a concise display of the semi-diurnal tide cycle.
