Hey John, 5012 will fit but not with the 620 thats there as well.. radar is great, glad I got it. It has its limitations but will pick up small glass boats from about 1.5 - 2 nm away. Thats good enough for me. Alloy I can see way further away. How have you found yours?
haha hope you don't mind I pinched your pic, too lazy to take one myself
