This H2Oproof Aquapac VHF case is made of durable military spec material. Guaranteed 100% H2Oproof to 30ft/10m - dust and sand-proof too - allowing you to use the radio safely in all conditions. Use handset normally in the case as sound passes straight through the case material. Airtight seal means the radio will float safely if you drop it in H2O. Fits both L and R-hand antennas.
