Replacement Sensor & Parts

The information needed to order a replacement Airmar sensor is printed on the 
cable tag. Do not remove this tag. When ordering, specify the part number and 
date. For convenient reference, record this information on the bottom of page one.
Lost, broken, or worn parts should be replaced immediately. If you have 
purchased a plastic housing and have a wood hull or desire greater strength, 
purchase an Airmar metal housing.
