Existing Bluetooth customers.
You can still use your existing Bluetooth Digital Gauge v3 gauge(s) with the new system but this system will replace the existing Hydrajaws Bluetooth Digital app that you have currently. 
Before the app updates, please ensure that you have saved any existing data (by emailing the finished reports) as all data will not transfer to the new system.
Any Bluetooth gauge fees that you have previously paid for in the last 12 months will be honoured.
