Jon,

water temperature was 4 deg Celsius. 
The motor compartment is sealed from the battery compartment, but still easy to
vent and dissemble.

Buoyancy is neutral at the surface, so it is swimming on the surface. Upon
starting the dive, it starts to get just a touch negative on buoyancy and the
scooter stays below the diver. That is really a nice feature this way. 
I bet you are wondering how this is done. >gr<

The trim can be adjusted. I got it in a slight nose up position, which may be an
advantage going through restrictions. But I like it better in a perfect
horizontal positon, and have set it so presently.

You should take a look at George's videos, where you can see how these scooters
are used and how good the maneuverability is. 

Regards, Reinhard
