The way I see it, for the fisherman like us I can’t justify it. I have checked my GPS speed and it’s close enough for my needs. There’s a lot more fishing stuff I could buy with that amount of money like a better fish finder or downriggers, etc. Pros or charters could justify it because it’s their paychecks are on the line. 3 man limits for us in a few hours of fishing is fine for me. Your fish finder is the critical piece you need. Hope this helps you out.
