    it is something we train in technical diving, however if you see rapid and erratic movement from a flashlight your natural reaction is to assume that someone is in trouble...

    Hello again,

    So in I went for 2 dives in 32 / 0 degree water, against a steady, 2 knot. current - what a blast! These scooters are definitely a fun ride! This river I have searched many, many times, yet the scooter gave me a whole new perspective on the bottom topography. My first dive was about :90, typical for this dive plan, but I got considerably colder than usual, as I wasn't doing much work! A few more layers will fix that.

    Attempted to blow away sand only once and found that I'll need to think through some rigging to allow me to remain stationary, as the thrust was pushing me up / back.

    Using 12Ah batteries, I found the scooter trim to be slightly negative, which was perfect. I did find the scooter would occasionally stop, and a line of dashes would march along the bottom of the view-screen for a few seconds, then the battery life symbol would appear and I could motor-on once again. This would occur at speeds of 4 & up to 6 and I assumed the combination of current speed & diver drag would cause the motor to get too hot, resulting in a temporary shutdown - is that assumption correct?
