I have used the Stubby II and both of the Baycos. I really like the 912T. The switch is easy to use and you can get a little bit more power if you want it. I generally hunt with one bulb and just switch on the second when I see a "hey what is that" type object.
I recently bought a rechargeable Bayco stubby-like light at Home Depot. It supposedly only lasts for 100 minutes, but I used it in Florida and it lasted quite a bit longer than that. It recharges quickly (less than an hour) in the 12V socket of my truck.
The best part is there is no cord, and no stinking lead acid 12V battery to lunk around. It weighs about the same as a maglite.
You could buy two of these and never be without light and save the herniated disk from lugging batteries around.
Or just walk for two hours, drive a while to recharge, walk, drive, etc. I don't know about the longevity of the batteries (how many recharges it will take).
It will be my wand of choice this year. Of course, I will have my 912T as a backup.
