### 3/5 — Give us more!

*2026-04-18, version 1.6*

I really want this to be my wilderness canoe fishing solution. It’s close, but not quite there. 

Some things I miss from my Striker 4 CV:

-travel speed. This is a gps dependent calculation. Why not add that layer to this device output?

-split map and sonar. This seems like a simple app update. 

-easy marker placement from any screen.
