Ok, I am sold in squandering $1K on a Garmin Panoptix plus a Multi Function Display after a lot of research.
I see the difference between P21-TR vs, P21-TM as follows:
(1). trolling motor mount vs. Transom mount
(2). Power cable and Ethernet cable (13 feet vs. 30 feet)
(3). Beam width (45 degrees by 90 degrees vs. 20 degrees by 90 degrees)
(1) and (2) are obvious, but (3)??? can anyone help explain this please?
Q1: What are the 2 degrees?
Q2: Is 45 a wider angle cone than the 20? so 45 can cover more water than the 20?
Thanks.
