built-in AIS 2 channel receiver is available now! In fact, I just ordered one a week ago through my favorite spplier, Defender. The unit is drop-shipped and expected to be here by sometime next week. The Watchmate does the same the Simrad AI50 does. Not in color but for half the money. Reading what you say about how you use or not use electronics, you may want to take another look at the Watchmate. Cheers, Ronald
