Used my striker 4 today for the 1st time and was highly impressed by it. Had it setup in dual mode and seem to like that feature much better than the flasher which works good but is not my thing at this point. I would mark a fish, jig alittle and then it was fish on. Also I used the supplied transducer and didn't see a problem so it also works as intended and I didn't have to make any guide redneck engineered rig for the transducer just what was supplied by Garmin. So if your a budget minded person this will suit your needs you get an ice rig and a boat rig.
