This AIS transponder has all the bells and whistles and performs very well. I typically track pleasure boats at 20 miles, commercial traffic at 30 miles, AToNs at 60 miles, and the record is a oil rig at 178 miles! It puts out a strong SOTDMA signal and have observed large ships alter course to avoid us when we were barely in visual range at night. I use the built-in GPS, have it mounted just below deck, and have not had any GPS issues. Installation was easy, the only issue is that there are multiple cables that plug into opposite ends of the unit, so finding a good mounting location was problematic. Also the wifi didn't work out of the box, I had to plug it into a laptop and use the utility program to re-enable it.
