Using different recorders in harsh environments such as humidity, heat, cold

I started this thread over at the taperssection forum, as that's where I came up with the idea for it, but it's more suited here. You can find the other thread at:

My hope for this thread is to try to gather as much information and user experience as possible about using different models of recorders in less than ideal environments, instead of having such information spread out as a sidenote in many long threads about them individually. How do they do in extreme heat and cold, moisture, problems with dust/sand etc? Maybe also a discussion of different remedies such as heat or cooling packs. This can be a help for anyone choosing equipment for such occasions, or what to expect/be aware of with the equipment they have.

For instance, the DR-680 is documented to be quite susceptible to heat over the value of 40 degrees Celsius that is given by the specifications, especially if it's not given some air around it. In cold, the LCD-screen, as is true for all I think, slows down, and might get damaged if left in such temperatures for a long period of time.

I heard quite recently from an experienced film sound technician, who often records in extreme cold and rain, that the sound devices recorders does not stand up to moisture very well. Maybe not nearly as bad as lower priced alternatives, but they are not as fool-proof as I had been given the expression of. They are also not specified to be used them in sub-zero temperatures. The only recorder I know of that is built to endure in extreme cold and high moisture is the Aaton Cantar.

Maybe it's better to have something like a SD mixer that is documented to handle extreme temperatures and moisture quite well, and several cheaper recorders, than one more rugged expensive one? Or maybe the cheaper ones deteriorate that much faster that it's not an alternative?

From the examples, I don't want to give the impression that only the more professional recorders are in discussion here, but also the smaller like the DR-100, FR2-LE etc.

I would especially like to hear from long time users who have spent several days or weeks using them in these conditions and can give some information about the long term reliability.

The small contribution I can make myself, is that the school I'm attending have an R-4 Pro that is used mostly for short films. During the winter it gets between -15 and -25 degrees Celsius, and it sees about 1-3 days of recording in these conditions for about 2-3 projects every winter. It's been used for a few years (I'm not sure exactly how long, but at least three), and it has never shown any problems that I know of.

Most, if not all, hard disk recorders will have some difficulty in the extreme cold. It's not so much the recorder as it is the hard drive. Hard drives need to get spinning, and if you are in sub zero temperatures, you may need to get them going in a warm environment, let them warm up, and then take them out. I experienced this back with the Deva II, and then the Deva IV and V when they came out. Solid state recorders should not be as much of an issue. It really comes down to the quality of the components. Higher quality components can handle a wider temperature change than lower quality ones, which is one of the reasons the high end recorders like the Deva, Cantar, and Sound Devices machines are expensive. The only recorder that I've seen that can get rained on, snowed on, and dragged through the mud and still work is the Cantar. It's kind of like the AK-47 in terms of it just working, but the menu system has a steep learning curve that many are put off by, not to mention the price.
 
That's good information - solid state should be better in cold.

About the Cantar, no kidding it has a learning curve! A mixer I worked with used one so I thought I'd try to get familiar with it, but reading through the manual several times didn't help much. Another sound recordist I talked to said the same thing - even with the manual and the machine in front of him it took quite a while to figure out how it worked. Although very heavy, it seems to be an extremely capable and durable machine though.
 
Most all semi and pro rigs come with a stated temperature range their manufacturers say you should stay within.
Usually the guarantee is voided outside those limits.

It's wise to do some location tests beforehand but even they can be unreliable with fierce chill factors.

On very cold days here, we keep all the SD recorders in rain proof Porta-Brace bags with small hand warmers. Never had a problem.

Cheers.
