About 6 weeks ago I saw something at Carter Motorsports that caught my eye. It was a little squeegee blade on a velcro strap, to be mounted on your clutch hand index finger. You use it for wiping your visor clean of mist or moisture. It's called the SeeBlade and costs around $7.
Now that I've had the chance to use it in varying conditions, I thought I'd post up my observations.
Overall it does a good job, particularly in drizzle and fog. It's easy to mount on the index finger of your left hand. Wiping your visor is like giving yourself a few slaps across the cheeks The squeegee blade cleans the visor nicely.
The SeeBlade works well in light rain and fog, but once the rain picks up you have to be wiping like mad all the time to keep up with the flow of water. That's not a fault of the SeeBlade; the rain is just coming too fast!
Also note that the water you wipe needs someplace to go: usually it collects on the finger with the SeeBlade. You better have good waterproof gloves or your finger (and soon your hand) will be wet and cold!
Anway, I think it's worth the $7 or so. Throw it in your jacket pocket for those times you need it.
