RuralMT I ended up going with the Garmin Striker 5 Ice Bundle after finding it on Amazon for $50 off MSRP and can say I haven't been happier with the purchase. While I never had the standard boat transducer, I have had zero problems with the iceducer you can get for the unit. I'm more of a graph guy anyways and have not experienced any type of lag or issues picking up small perch jigs with the iceducer in 50+fow. I can actually pick up the spikes hanging off my jigs when hunting for perch. I've also used it with buddies who have had the gamut of flashers (Marcum, Humminbird, Vexilar) and the one thing I've found is I don't have any issues canceling out the noise from their units. I've also kept competitive with these guys on fish through the ice. I'm not sure about the Striker 4, but if it has the chirp sonar paired up with the iceducer I don't see how you can't be happy with it. I would recommend this to anyone and have been extremely impressed with Garmin.
