TripleGage

Many may perhaps not realize, but this is a more than highly useful tool! The US military used to issue similar to those stationed in cold weather environments (Northern Europe/ Asia, and Arctic...). It can assist in many ways with both ambient temperature approximation as well as with additional wind chill with the wind chill chart on the back! Thus one can ascertain, roughly, weather hazards that may impact activities and or level of dress in areas where a simple training exercise or outdoor cross-country ski- hunting-snowshoe- snowmobile-outing can in fact potentially turn into a survival situation very rapidly! The magnifying glass, in addition to being utilized to read a map or fine print, could potentially also be used to start a fire with sunlight if needed. The compass, although not precision, is good enough for cardinal directions, which can be more than useful in a "whiteout" situation or dense fog-limited visibility and as a backup should one loose their primary compass or means of land navigation, as well as other essential equipment! This is perfect addition to the M-65 Field Jacket and liner as well as M-65 Filed Pants and line (at amazon.com https://www.amazon.com/Rothco-M-65-Field-Jacket-Olive/dp/B00026LI58/ref=sr_1_2?crid=EX4BKULGN2LF&keywords=rothco%2Bm-65%2Bfield%2Bjacket&qid=1547875710&sprefix=rotcho%2Bm-65%2Caps%2C162&sr=8-2&th=1 AND https://www.amazon.com/Rothco-Vintage-M-65-Field-Pants/dp/B002PQVJUC/ref=sr_1_1?keywords=rothco+m-65+field+pants&qid=1547875772&sr=8-1 AND https://www.amazon.com/Military-Field-Liner-Weather-Trousers/dp/B00F3G8H74/ref=sr_1_1?keywords=m-65+field+pants+liner&qid=1547875826&sr=8-1 in order) that have good strong brass zipper systems that can be handled with gloves on (i.e. not flimsily cloth pull tab on small light-duty plastic zipper), or other such easily adaptable and rugged outerwear! This item can also be utilized as a small straight edge and would have bee great had a small distance measurement scale been added. Small but highly useful tool, one should have in extreme cold weather environments as both a quick weather-direction approximation tool and as a backup survival tool!

If it's an analog zipper pull that you've always wanted, this is the one. Solid; thermometer is accurate (I calibrated it. ) Compass is damped by liquid. Good item.

Contemplated giving the zipper pull triple gauge a 3 stars, but I decided on 4 as it is constructed very well. And here is why: Pro: 1.) As a zipper pull, it performs as stated. 2.) Lens is clear and w/o defect. 3.) Compass verified against navigational compass, reasonable enough if one understands what it is. 4.) Thermometer within 2F of calibrated unit. SO, the above is the reason for 4 stars. Now the negative. I shall explain. 1.) Wind chill chart on reverse begins at 5F. Flesh is already in the caution to danger zone long before. Perhaps this is of value for northern part of states bordering Canada or Alaska. I have older Sun zipper pull units that are sooooo old, the chart is severely worn off. Those older Sun units started at 45F, and charted colder temps. Very useful. In my opinion, the chart that was used had the most useful portion inadvertently removed to fit the new design. Had the most frigid aspect of the chart been removed instead, I would give this Sun version a 5+ rating. This would be a five star item if the chill chart placed on this started at 45 like earlier version and reduced in increments of say 10. Of great quick reference, having the caution zone in yellow background, then danger zone in red background would have been an awesome EDC device. SSgt. Dave

The backplate wasn't glued or pressed in correctly so it fell off within a week and is gone. It is smaller than the front plate so the key ring doesn't go through it. I had a campmor version of this for 20 years and missed it. I am debating to be fooled twice. The compass maybe was a good addition bc it is still considered an essential and I have been in situations were I needed a fire starter, although not always sunny. Adding whistle etc is getting dorky. A smaller (1/2 size) sturdier thermometer only would be better with the ring going through both sides or having a single side for durability.

I have one of these on every laptop bag. I never leave home without one. Imagine you are visiting a new city. You arrive at the airport, take the train into the city, get off at the station your business contact said to use. He also said, walk two blocks north and you'll find his office. But it's overcast and you don't know which way is north. But with this on your bag, you do. You can also use the built-in magnifier to find that splinter in your finger and take it out with your tweezers. (You do have a Swiss army knife, right?) And when you arrive at your hotel and the room is freezing or boiling, you can tell the front desk that it's frigging so many degrees in here.

Poor construction. The red alcohol tube is turned slightly sideways, so the temperature can’t be read with a straight-on view. Very irritating.

I don't know why some people are complaining about the compass. Mine works very well indeed, it's fluid in movement and points to north accurately. Perhaps some received a defective product or their compass got demagnitized. Temperature is also accurate, and magnifying glass is very useful. Three items in an ultralight weight package saves me extra weight in my backpack. Recommendation: Add Celsius scale too, which is more helpful is cold temperatures.

For some reason I like to know if the temperature is to blame for how hot or cold I feel. The thermomer is roughly acccurate +-5 degrees and for its little size is perfect. Sometimes hard to read in the sun but doable. Mine had a tiny red mark on the inside of the plastic housing which apears to be how the thermometer was adjusted during manufacturing but the red mark doesn't bother me. The compass works ok and the plastic housing hasn't cracked.

温度計やコンパスのことは判りません。要は耐久性です。前に使っていたものは気度計の裏がすぐに剥がれてしまって、気がついたら気度計が無くなっていました。これはその心配がないつくりになっています。防水性を考えてのことなんでしょうね。ただ、がっちりとカバーされているので気度計は不正確かもしれませんね。わかりませんけど。

this product does not have celcius on it.

まだ開封していませんが、パッケージも綺麗なので、そのまま飾ったままです。 他商品と違ってレンズ機能がある分、アドバンテージがあると思う反面、サイズはやや大きめです。

キーホルダー程度の大きさ(写真を見ればその通りなのですが)で、びっくりしましたが、まあ、かわいい感じで気に入ってます。

小さくて衝撃にも強くて、温度、方位を知る事ができて大変便利なミニEDCサーモメーターです。
