Can regular binoculars be left in a car in the summer and not get damaged from heat?

As long as the lens are made of glass and the frame is either metal or a very heat dense plastic that can handle intense temperatures.

Laws vary by jurisdiction. Generally, it is not a violation to "warm your car up in the morning," however, there many be a law about leaving your car running unattended.

Well, it's getting near summer. The weather is warming up. Don't you think your helmet will be too hot? How 'bout just your cap?

For car camping, I love my Pyromid. http://www.pyromid.net/ It can use charcoal, sterno, wood, etc or it can be set on top of a camp stove or BBQ grill. It is solid stainless steel. It folds up into a package about 12" x 12" x 1". (There are larger and smaller models too.) I can use it for grilling steaks, griddling pancakes, even baking a whole (small) chicken and a pan of biscuits.\n\nFor advice on a backpackers' stove, call REI.

For Justme any tool is OK to be used.  All tools and wheels must be in the pit box before the car can legally leave the pit box, they do not have to be behind the wall.

Just make sure you are swimming slightly b/c if you are not moving you will get a heat shield ora thing around you. Similar to that fume thing when you put gas in your car.

Not in any atmosphere you could survive in. It is possible that the picture may deteriorate or fail to function but it is the electronics going out of limits.

Depends of if the body temperature is the same as the surrounding, for example a snake that has been sunbathing for a few hours before dark will remain warmer than its surroundings for some time, so thermal immagery devices could have limited use. I'd say a flashlight or headlamp would probably be just as much use in most cases tough.

You can make a dew shield, which is basically an extension of the telescope tube, by rolling cardboard or a plastic camping mat into a tube shape and attaching it to the end of your telescope tube. Dew only collects on exposed surfaces so if the optics are far down a tube they are less likely to fog up. Many people keep a hair dryer nearby for drying off the telescope. There also commercial dew heaters that battery powered and attach to the telescope.

No real need to do much before you put them into storage, but the wax will dry out over the summer so they'll need a wax before you hit the snow next season.

Yeah, attached to wheels and calibrated according to size.\n\nWorks fine unless you are a skidder on the road, and cover a sizable portion of your journeys with the wheel locked. ;)

No.\nThe Sun may be visible for more than one day over the geographic North Pole during the Summer, but the day is still only about 24 hours long.

Sure they can be useful.  If you're camping where you don't have access to electricity, for instance.\n\nThere are problems of course.  A bright flashlight uses a lot of power and there isn't enough surface area for solar cells to capture much energy throughout the day.  So you get a few minutes of use from a whole day of charging.  The newer LED flashlights go a long way to fixing that, though.  And usually it's not a problem because you don't usually need flashlights every night for long periods of time.\n\nAlso you really would want to charge the flashlight outdoors because there isn't very much energy in indoor light.  Sure it's enough to charge a tiny calculator battery, but flashlights need a lot more.  But leaving it outdoors exposes it to the heat/cold/rain/snow/wind/thieves.\n\nDon't store it in the toolbox. :)

It has happened and far to often.  I read a story about a young father taking his two year old son to day care on his way to work because his wife was sick and the stress of the day he forgot to drop him at the daycare and left him asleep in the back of his car when he got to work.  The baby wasn't discover be for being dead for two hours.  The daycare tried to call the mother at home but she had taken the phone off the hook so she could rest and the father's work number was not listed with the daycare center.I think your concern is well placed and I believe there could be many ways to alert the drive of a child or animal left in the car.\n\nGeneral Motors Develops Device To Prevent Heat Stroke in Car Occupants.\n\nCOPYRIGHT 2001 The Washington Times \n\nByline: Tom Ramstack \n\nApr. 27--General Motors Corp. announced yesterday it is developing a radar technology to prevent heat stroke in children and animals left in automobiles on hot days. \n\nThe radar detects the presence of people or animals by their normal movements, such as eyelids blinking, mouths moving or chests inhaling and exhaling. A second device monitors temperature inside the vehicles. \n\nWhen the temperature rises too high while children or animals are inside, the device sounds three short blasts, or "chirps," of the automobile horn. \n\n"We have many parents who are unaware how quickly a vehicle heats up," said...

Here's an idea for you... you know how those with handicapped parking mirror hangers always have to do something with the signs (put in the glove box or just leave hanging there) so they can legally park in the handicapped parking spaces?  How about inventing a velcro patch that sticks the hanger to the car's ceiling?  This would make it safer for drivers when their views are unobstructed.  And it's simple to develop, too!  \n\nGood luck!

www.opticsplanet.com has decent section on birding binoculars, and what to look for them.  Bear in mind they are a retailer, looking to make a sale.\n\nI have purchased from them before, and they have a pretty good reputation.
