I ordered a Garmin ECHOMAP UHD 73sv with LakeVu G3 yesterday. Small compared to many, but definitely big boy for a kayak. GPSstore on line had it for $499 ($200 off). The funny thing is I don't need it for Crappie, hoping to use the sideview to locate deep gills beds in the spring. In clear water I've found many as deep as 8 feet.
