The real good point here is battery life. With lithium ion you lose 1/8 of your charge per year, especially in winter conditions. It estimates it at max 8 hrs runtime. Likely, unless you're huddled in your hut next to the heater, it will be more like 4-6 from cold weather. Next year that's 3-5, and so on. You can hook it to an external source, so maybe a small battery pack plus micro camera would still be a lot less luggage than the big girl.
I really like the big one, but it is a heavy bulky sucker. No screen probs, I got the deluxe with the screencovers and the lcd you have full control of. On REAL sunny days you gotta stick your face right in there, otherwise it's good. Amazing in my portable hut, we call it "the video game" and really enjoy watching all the fish not bite our baits. Lol
