How do I know if my WaterRower model is Upgrade Package compatible?
The Ergatta Upgrade Package is only compatible with wooden frame WaterRowers that have an S4 monitor. Please note, that to be fully compatible you need to have the most current version of the S4 monitor (known as the S4 v2). The current S4 has a micro USB port in the back of it.
The WaterRower Model Identification hub can help you determine your exact model.
