A bunch of replies, but no one replying to my original question
Travis, that yellow tank is an Airmar M260, to the best of my knowledge they don't make that tank in 1K wide angle, if they did I would install one.
I have a B260 now.
Awesome for deep water as both the M260 & B260 are narrow beam, 6 degrees @ 200 & 19 degrees @ 19 degrees.
Not so great for shallow water
I'm planning to add a 2nd ducer but wide angle which is much better for shallow water.
My options as told to me my a girl @ Airmar a SS270w which is a wide angle (25 degrees @ both 50 & 200) or go down to a 600 watt instead of a 1K
Back to my original question, how will it effect the boat having 2 of those big blue fairing blocks hanging below the boat, 1 stb & 1 port ?
