This only my two cents worth. I don’t have either one. This is for the ladies and gentlemen that can’t afford forward facing sonar!!! I was in my boat trying to learn how to fish deeper water. 10-15 feet. I fished by a boat. A nice boat loaded with all types of units plus forward facing sonar. In the heat of the summer on a lake. I said to the men. Man!!! You need one unit on that pretty boat. His reply was. If I had room I’d have more. I had two hummingbird 899 on my 16’ war eagle. I was fishing what I could find in 10-15 foot depth range. He was fishing shallow docks. My point is. The AVERAGE fisherman buys this stuff and doesn’t take the time to really learn it like we all should. So!!!My two cents worth. I’d say 60% can’t afford it like me. 30 percent buy it but obligate there time to it. Five percent try like heck to figure it out. The last 5 percent!!! Well there the ones that can afford it,and willing to grind to figure it out. Those are the guys that kick my azz every month 😂😂😂point is. Work with what you have 👍
