Garmin echomap 73 sv plus units. With extra bases. I fish alone 90+% of the time. Can put both on the bow or console.
Once the Q1 update is released, they will share sonar and waypoint, when Ethernet connected.
I've only had them out once, I'm more than happy.
With active Captain app, you can view your maps on phone. To get a plan together, before you leave.
They come preloaded with 17000 lakes, 13000 of which have 1' contours.
If you need a better mapping, you only need one card for the whole country.
1 micro SD card slot.
If mapping isn't required, get the striker series. Same ducer and images as echomap. Has a basemap that's waypoint capable. No sd card slot.
Both above are quickdraw capable.
Drinkin coffee, missin fish.
