Compasses & Barometers
A good selection of very useful compasses and barometers are available to purchase. To help predict and forecast the weather we have three barometers to accurately measure and determine atmospheric air pressure. The impressive GTD 1100 features a barometer, altimeter and thermometer. The array of compasses we supply will help with a variety of location based surveying tasks. All the compasses we have available are accurate; however for harsh working conditions we suggest the Silva A40 which is durable and made from scratch resistant plastic.
