I got my Marcum 350 last week and I love it . Have used it in 20 feet of water and last night eye fishing it is great , pitch dark out and cuold see the walleye just great and the 350 right now is $219.00 at Gander in Madison.
I know this is a very old thread but I found it when searching Marcum 350. I read your post Jeff and I am wondering how you used the UC at night. I bought my Marcum VS350 around 10 yrs ago and have never been able to see after dark. I adjusted everthing and since the water is full of tiny particles when the infared lights shine on them that’s all I can see. Maybe you use it in a crystal clear lake. Now out of the water it works great in the dark.
