I'd record to the INT HD to create more heat but I'd forgo the hand 
warmers. I've left my 744T out numerous times for 16+ hours in 
sub-zero temps inside a rip-stop nylon fanny pack with the zipper 
left open about two inches for ventilation. I suppose if you left the 
recorder case exposed to the air, the internal temperature would drop 
low enough to cause problems. but surrounded by one, fairly air-tight 
layer, controlling the temp is a matter of adjusting venting. There's 
plenty of heat generated. Summer creates greater concerns for me. Rob
