I am almost certain that you will be safe. Permethrin is not particularly toxic to humans, and exposures of notably higher concentrations than what you used for the clothing treatment have been found to not be a significant issue. In fact, there are treatments for head lice using 1% Permethrin, applied directly to the scalp, so I wouldn't worry too much ...

Water. The American Red Cross Wilderness First Aid courses in 2021 recommend irrigating wounds with at least a liter of potable water, using an irrigation syringe. If you don't have enough potable water, washing with non-potable water is acceptable and you should finish off with potable water. The stronger antiseptic chemicals are indeed antiseptic, but ...

All GPS navigators on the market work as you’ve described. Two way communication is very battery intensive and costs money, so it’s only included in PLB beacons or devices like Spot, not your average GPS device. Some of them let you connect to WiFi or add a SIM card to download map or traffic updates but this is completely optional. So get the cheapest GPS ...

You are probably best looking at older and cheaper models to achieve this lack of functionality. Therefore you should look for models that don't advertise bluetooth connectivity, app integration or wireless connectivity. A curent example is the Garmin eTrex 10 which seems only to receive GPS signals, not to send or receive other data wirelessly. In this case ...

Y'all are way overthinking this. Get an old and/or cheap smart phone. Don't put a SIM card in it. Install some basic GPS app and then tell it to forget the WiFi network (and turn off WiFi). If you don't need maps, you're done. If you do, I wouldn't be surprised if there are apps (probably OSM based) that let you side-load offline maps from an SD card; you ...

When someone is so badly injured that they need immediate professional medical treatment, and you are able to get them that treatment within a day, then wound disinfection isn't a priority. Infections take days to set in, and modern antibiotics administered at the hospital can prevent that from happening. According to several first aid courses I did, trying ...

There are two factors to care about here: a static rope and a rope that is slightly too thick. Static ropes are usually less flexible than dynamic rope, which would explain the stubborn feeling. 0.5mm of thickness is generally nothing to worry about. The main concerns with the manufacturer-approved ranges of rope thickness are safety and "user ...

drugs.com notes the Usual Adult Dose for Scabies is a Permethrin topical 5% cream, applied by thorough massage into the skin. 30 grams. That's essentially 1,5 grams pure permethrin applied to the skin directly. I don't recommend doing so unless it's required, but if your spray is 0,5% and you've applied twice what is recommended, it would seem you're still ...

Having perused my well read copy of NOLS Wilderness Medicine (available e.g. through NOLS), there is no mention of hydrogen peroxide use at all. The only two things mentioned for wound cleaning are (1) water, and (2) water with povidone-iodine. Use of a syringe to irrigate the wound is strongly suggested. If you have limited clean water, rinse with untreated ...

Answering the updated question: Get a device that uses an external memory - i.e. (micro) SD card for the maps. You will never connect the device to a computer and may still have the actual maps on the SD card, just use a card reader. You can always sanitize the SD card prior to accessing it with the device's software (up to and including a complete ...

While maybe not as "extreme"/"gadgety" of a help as what you are looking for, you'll often see pink lenses marketed for whiteout conditions in snowsports as it helps to increase the contrast. I've been unable to find a totally definitive answer as to the physics/biology behind why this is the case, but the best I could find is the ...

If unable to change fuel, as others have mentioned... as a youth I would spread dish soap (like dawn) over the outside of the pot (where the flames would hit). Then heat up my water/cook on a wood fire which would get the outside of the pot covered in soot. However, because of the dish soap, it came off easily during cleanup; and I would discover any spots I ...

Knowing the model and seller for this backpack was the key. From their website, I found this info about the buckles: BUCKLES (COMPONENTS) We use aluminium buckles on all our Maverick bags. These are tough enough to withstand an average force of around 122 kgf (kilogram force). The aluminium is anodized, which provides a weather resistant surface without ...

Double-back your buckles as on a climbing harness? If you can weave the strap around the bars in the buckle differently, you can change the level of friction at the expense of convenience. Here's a common 4-bar buckle: You can add some friction by tucking the loose end upwards under the top bar (double-back): Or you could rethread it a couple ways (These ...

Nails will be extremely useful at a Bug Out Location (BOL), not so much in the Bug Out Bag (BOB) or even the Bug Out Vehicle (BOV). That is why I keep an extensive cache at the BOL, which includes woodworking tools and a large assortment of stainless steel nails. Most of what I cache in terms of woodworking/construction were extras and duplicates of other ...

I learned this tip from a former Navy Seal. Dip your finger in rubber cement and rub it on the full length and width of web straps. Both sides. Let it dry, then rub off whatever comes off. It adds a tremendous amount of "stay power" to your straps.

I added a bit of velcro to my shoulder straps with hot glue and it's worked perfectly. Get velcro at any fabric or craft store. These are for my shoulder straps, which often slipped when I took big steps down on a descent. I added a small (1.5") piece of the "hooks" velcro to the end of the strap and then several inches of "loops" ...

What you're looking at is a carbide lamp, and it looks to be a Petzl Aceto. What you can't see in this photo is the generator, which is a round canister with two parts. The upper part contains water, which drips into the lower part containing small lumps of calcium carbide. The reaction releases acetylene gas, which travels via a tube to the actual lamp. ...

This is common with Trangias. I used to find the same in the UK when I used them. My miniature alcohol stove does the same. I've never found a way to prevent it occurring, though it can be made easier to clean off. Like you, I've never found a dishwasher to do anything to it, though any that doesn't come off with a cloth won't come off easily. A few ...

Another low-tech solution for dealing with a severe whiteout is to throw something ahead of you that is highly visible. This generally takes the form of a small, brightly colored stuff-sack (filled with snow or similar) attached to the end of ~5--10m of brightly colored cord or thin rope. Throwing the stuff-sack in the direction you wish to head and ...

The Wikipedia article on pearl hunting includes a photo of a diver with no mask in the water. So certainly some diving was done with bare eyes into the 20th century. However this article on Japanese and Korean pearl divers (Scientific American 1967) mentions a century of goggle/mask use. (Note, the article contains uncritical discussion of ...

I wish there was a solution that's both practical and 100% data secure, but I don't know of one. An open source phone, as suggested by Matthew, is probably the closest, but with that you unfortunately still need to expect to run into reliability problems – not something I would risk in the outdoors. Also, open source phones are probably among the products ...

Actually, having looked at the manual online it makes more sense than I remembered. Having the active rope pass through the broad end provides more friction than if it is inserted through the thin end.

The design benefit of these emitters is that the brightness comes from a much smaller area. This means that the optics can focus the light into a smaller spot. There doesn't, at the moment, seem to be an efficiency benefit over the best LEDs, except perhaps in low power modes. This is partly because current designs are optimised for maximum brightness. ...

The article linked in the answer you linked What is the best way to re-waterproof a nylon tarp? says it won't work as well for tent floors when compared to PU: http://jwbasecamp.com/Articles/Silnylon1/index.html For the tent uppers and fly canopies, it could work well. Silicone is good for repelling and shedding water, but not for being an actual water ...

According to their FAQ: Does the SPOT X turn off if it's idle? No, the device does not need to turn off to save battery. The SPOT X uses technology which allows it to use very little power when not actively sending messages or navigating. So there is no "sleep" mode on Spot X.
