Cut to the chase, I got my long non-working Garmin 840 back. (FYI Garmin sent me a refurbed one, I''m assuming it's not the exact one I sent in but I didn't check the serial numbers) (they did get it back to me quickly)

But I digress,

Back to the fun, I got the 840 out today to see if it was indeed working. I couldn't find crappie so I went perch fishing. I was using a spoon with 3 flys (small flys, one inch, 2 inches) I tied above them.
THe 840 was showing the spoon and 3 flys above clearly as I jigged it. Very cool. very clear with the chirp ducer.
Will it help me catch fish? I don't know but if I can't it's my fault, not the Garmin.
