I have a Humminbird Piranha Max 210 portable fish finder. It is wired for a 12 volt battery . (You can fish all week on a charge ) It is only used on summer holidays ,less than 3 weeks of use . Excellent condition . $90.00 Thanks
Yes it can be used for icefishing.
Either you can buy an icefishing transducer or rig up the one you got so that it hangs in the hole pointing straight down. Some put it on some type of stick but I did it this way.
Great idea Woodsman, now I think I can justify buying a portable. I spend more time on the ice than the water but it would be handy to have a portable for the boat and hut. Did you just bend a piece of flat bar for the transdoucer? It take it the foam is just a float.
