I bought the Standart Horizion HX 870 from MEC. Found it on sale last year at Steve stone marine and MEC price matched. It’s GPS enabled. It has a rechargeable battery as well as ability to power with 5 AAA batteries…which might come in handy on long trips.
Taking the radio course April 26th with the port moody power squadron. You can also buy material online and then arrange to take test with one of the squadrons.
