Hi Bros and Sis's, I am taking a trip to Canada in the spring to fish at a fly in camp. Unfortunately, the boats that are provided have no fish finders on them. The lake is big, and I'm sure I'm going to need all the help I can get to find dinner! What is a good (not great) fish finder that I could take with me? Weight is a slight issue, I can only take 100lbs of total equipment with me on the float plane. I was going to just go out and buy whatever I could find, but it's always good to get some educated info from my Bros and Sis's! Thanks for your help!
