I realize this is a long shot…
I have an older Lowrance iFinder H2OC. Good unit, finds satellites, reads my Lakemaster chip just fine. What I’d like is a chip that has topo map information in it. This would come in handy when I was hunting or walking along a trout stream. I did some searching and couldn’t find much, probably due to the age of this unit.
Any ideas?
