Warranty Information

Shearwater has a 2 year warranty on all products. The warranty lives with the unit, not with the original purchaser. This means that whether you buy your unit from our dealer network or second-hand the warranty will still be effective. Once the warranty period has passed computers should be serviced every 2 years at your nearest service center. It is unnecessary to register your unit upon purchase. Every Shearwater unit is tracked with a unique serial number.
