Fishfinder on the ice?

  That's what Iv'e done for yrs. when ever I venture out without any problems. You can get creative on the mounting hardwarefor the transducer.

I use my ice flasher on my kayak come open water, yet I never thought of using my portable finder on the ice haha. I might have to try that when we eat ice back.

I've been using a portable Eagle for about 10 years.  I attached my transducer to an old-school tip-up frame, and it works great.  I taped the cable to the vertical piece of the frame.  I don't like it as much as the Vex my Dad uses, but it's good for depth, and it shows fish and lure/bait well.  I turn off the fish I.D. and turn up the sensitivity.  I feel blind without it.
