"Being watertight and shock-proof the Digital Camera Module can comfortably be used in adverse weather conditions...."

Is the DCM unit weather proof?
It is watertight.

How long the battery can last?
I am afraid it is "using pattern" depended.

Is the image viewable?
Personally, I am using NEX 5N with EVF in digiscoping. I can not view the LCD screen under strong sun light, but somebody can do.

Dear Kenny,

I'm just a small potato, not Dr.

I have never played with this, I think that a 2” LCD screen is too small for pure bird observation purpose, it is better to say a viewfinder rather than a monitor.

I can not find detail specifications/information mentioning the power consumption/battery capacity on their website for my calculation, but I think it can last for 2hrs. I recommend using DIY external battery pack after you bought it.
