Jim Coleman Water Wizard 1.0 and 2.0 Count Wheel

The first picture (white motor) is from a Water Wizard 1.
The second picture (black bag) is from a Water Wizard 2.

I am not familiar with the WW 2.0 but it appears from the pictures that the 2.0 has 2 sensors where the WW 1.0 has 1 sensor…. For counting.

Also just as a note: The WW 1.0 wheel is supposally a 5.5×1.5 plastic lawnmower wheel
I actually purchased an extra…. It is somewhere! 🙂
