TOPIC: Navionics and sonarphone

I have navionics on my phone and tablet. I find the charts are accurate, and it nice having 3 sets of chasrts to compare.

Now I see they have a sonar device that can interface with your phone.

Does anyone use sonarphone? If so do you like it?

I have a lenovo tablet with a kickstand. Would fit well on the dash and spitnscreen would give me sonar, charts, speed, and location all together.
