Rite in the Rain Tactical Field Book

Rite in the Rain Tactical Field Book

10+ years

Rite in the Rain's Tactical Field Book uses a patented all-weather paper that sheds water while accepting pencil, all-weather pen, and even standard ballpoint in dry conditions. The paper won't disintegrate in rain, mud, snow, or sweat. The tactical version features a reference card system in the cover with conversion tables, map scales, and reporting formats.

What owners say: Owners in field research, military, forestry, and SAR rely on these in conditions that destroy standard notebooks. Notes taken in a downpour are still legible when dry. The paper accepts pencil marks even when soaking wet. Many owners have field books from decades ago still perfectly readable.

Watch for: Standard ballpoint pens smear on wet all-weather paper โ€” use pencil or an all-weather pen (Fisher Space Pen, Rite in the Rain pen). The paper has a slight waxy feel that some people find unusual. Printing is slightly less crisp than on standard paper. Costs more than regular notebooks but lasts indefinitely.

Alternatives Worth Considering
Rite in the Rain Top Spiral Notebook
Also Great

Rite in the Rain

Top Spiral Notebook

The Top Spiral format is more conventional for everyday field notes. Same all-weather paper with a spiral binding that folds flat. Available in pocket, field, and universal sizes. The most versatile Rite in the Rain format for general outdoor use.

Field Notes Expedition Edition
Value Pick

Field Notes

Expedition Edition

Field Notes Expedition Edition uses Yupo synthetic paper that is waterproof, tear-proof, and stain-proof. Not cellulose-based paper at all โ€” it's a thin plastic sheet. Virtually indestructible but only accepts certain pens (not pencil). The most durable notebook paper available.

Electronic Flare

โ†‘
ACR ResQFlare Electronic Flare & Flag

ACR ResQFlare Electronic Flare & Flag

5-10 years

The ACR ResQFlare replaces traditional pyrotechnic flares with a USCG-approved LED distress signal that runs for 20+ hours on a single battery set. No fire risk, no expiration concerns, no hazardous materials disposal. The included SOS flag meets day signal requirements. One device replaces a full set of pyrotechnic flares and lasts years instead of 42 months.

What owners say: Owners on boats appreciate eliminating the fire risk and disposal headaches of pyrotechnic flares. The LED is visible for 10+ nautical miles at night. The flag satisfies daytime distress signal requirements. Coast Guard-approved means it's legal as your only flare kit.

Watch for: Batteries need periodic replacement โ€” check annually. LED visibility in bright daylight is less than a burning flare at close range. Keep the lens clean. Not all electronic flares are USCG-approved; verify before relying on one as your only distress signal.

Alternatives Worth Considering
Sirius Signal C-1003 SOS Distress Signal
Also Great

Sirius Signal

C-1003 SOS Distress Signal

The Sirius Signal C-1003 is a compact, one-handed electronic distress signal with automatic SOS pattern. USCG approved for day and night use. The smallest form factor in the approved electronic flare category. Lithium battery lasts 6+ years in storage.

Orion Electronic SOS Flare
Value Pick

Orion

Electronic SOS Flare

The Orion Electronic SOS Flare is an affordable LED distress signal with both SOS and steady-on modes. Not USCG-approved as a sole replacement for pyrotechnics, but legal as a supplement. Good for inland water, camping, and vehicle emergency kits.

Faraday Bag

โ†‘
SLNT Faraday Dry Bag

SLNT Faraday Dry Bag

Lifetime

In an emergency context, the SLNT Faraday Dry Bag serves a different purpose than in data backup โ€” here it's about signal security and EMP protection for critical electronics. Store your emergency radio, GPS, and charged phone inside to protect them from electromagnetic pulse events. The waterproof roll-top closure also protects gear from flood and storm damage.

What owners say: Owners in emergency preparedness communities keep charged backup phones, radios, and batteries inside Faraday bags as part of their EMP-resilient kit. The waterproof feature adds practical value for storm and flood scenarios where electronics need moisture protection.

Watch for: Test your bag periodically by placing a phone inside and calling it. The roll-top must fold at least 3 times for proper shielding. Don't store devices while powered on โ€” they generate heat in a sealed bag. Keep desiccant packs inside to prevent condensation.

Alternatives Worth Considering
Mission Darkness T10
Also Great

Mission Darkness

T10

Mission Darkness T10 offers dual-layer RF shielding tested to military specifications. The larger size fits laptops and tablets. Heat-sealed seams prevent signal leakage. Preferred by law enforcement for evidence preservation.

Edec OffGrid Faraday Bag
Value Pick

Edec

OffGrid Faraday Bag

The Edec OffGrid is the most affordable Faraday bag option. Single-layer shielding blocks common frequencies. Best for casual EMP preparedness and phone privacy. The velcro closure is easier to open/close than roll-top designs.

Fire Starter

โ†‘
Ferro rod (Bayite 1/2

Ferro rod (Bayite 1/2" Drilled)

Lifetime

A ferrocerium rod produces 5,500ยฐF sparks by scraping a steel striker along its surface โ€” hot enough to ignite natural tinder, char cloth, and commercial fire starters in any weather. The Bayite 1/2-inch rod is thick enough for thousands of strikes and drilled for a lanyard. No fuel to evaporate, no flint to crack, no mechanism to fail. This is the most reliable fire-starting method that exists.

What owners say: Owners in bushcraft and emergency preparedness consider a ferro rod the ultimate backup fire starter. The 1/2-inch diameter provides enough material for 10,000+ strikes. The bright shower of sparks works in wind, rain, and snow when lighters and matches fail.

Watch for: Technique matters โ€” practice before you need it. Scrape away the black coating before first use. Keep the rod and striker dry between uses to prevent oxidation. A ferro rod requires good tinder preparation; it won't light damp wood directly. Carry dry tinder or commercial fire starters as companion materials.

Alternatives Worth Considering
Exotac nanoSTRIKER XL
Also Great

Exotac

nanoSTRIKER XL

The Exotac nanoSTRIKER XL is a machined aluminum ferro rod tool with a built-in striker and replaceable rod. The precision design makes it easier to use than a bare rod. The aluminum body is waterproof for storing tinder inside. Premium price for premium execution.

UCO Stormproof Match Kit
Value Pick

UCO

Stormproof Match Kit

UCO Stormproof Matches burn for 15 seconds each in wind, rain, and even after being submerged in water. The waterproof case holds 25 matches. Not a ferro rod but arguably easier to use in an emergency when fine motor skills are compromised by cold or stress.

Personal Locator Beacon

โ†‘
ACR ResQLink 400 PLB

ACR ResQLink 400 PLB

5-10 years

The ACR ResQLink 400 is a Personal Locator Beacon that transmits your GPS position to the global COSPAS-SARSAT satellite system on 406 MHz โ€” the same system used by aviation and maritime distress. One button press alerts rescue services worldwide. No subscription fee, ever. The 406 MHz signal is monitored by every rescue coordination center on Earth.

What owners say: Owners in mountaineering, offshore sailing, and remote fieldwork carry PLBs as the absolute last-resort emergency tool. The confidence of knowing rescue services receive your exact GPS coordinates within minutes is unmatched. No cell coverage or satellite subscription needed.

Watch for: PLBs are one-way devices โ€” you can't receive confirmation that help is coming. Battery must be replaced by the manufacturer every 5 years. Register your PLB with NOAA before carrying it. Test monthly using the built-in self-test (does not transmit). A PLB is not a communication device โ€” it's a rescue beacon.

Alternatives Worth Considering
Ocean Signal RescueME PLB3
Also Great

Ocean Signal

RescueME PLB3

The Ocean Signal RescueME PLB3 is the world's smallest PLB โ€” lighter and more compact than the ACR with the same 406 MHz COSPAS-SARSAT capability. The PLB3 adds a return link service that confirms rescue has been initiated. Ideal for ultralight packs.

ACR ResQLink View PLB
Value Pick

ACR

ResQLink View PLB

The ACR ResQLink View adds a small screen that displays GPS coordinates, battery status, and transmission confirmation. Same 406 MHz PLB functionality with the added reassurance of visual feedback that the beacon is transmitting. Slightly larger than the standard ResQLink.

Signal Mirror

โ†‘
Adventure Medical Rescue Flash Mirror

Adventure Medical Rescue Flash Mirror

Lifetime

A signal mirror is visible up to 25 miles in direct sunlight โ€” farther than any flashlight, flare, or smoke signal. The Adventure Medical Rescue Flash uses a retro-reflective aiming grid that makes targeting aircraft and search parties intuitive. No batteries, no expiration date, weighs one ounce. This is the ultimate zero-infrastructure signaling device.

What owners say: Owners in backcountry SAR and military service call signal mirrors the most underrated survival tool. The aiming grid eliminates the guesswork of traditional mirror signaling. The polycarbonate construction is virtually unbreakable. Practice the aiming technique before you need it.

Watch for: Only works in direct sunlight โ€” useless at night, in heavy cloud cover, or dense forest canopy. Keep the reflective surface clean and unscratched. Store in the included pouch. Practice aiming at a target before relying on it in an emergency.

Alternatives Worth Considering
Coghlan's Sight-Grid Signal Mirror
Also Great

Coghlan's

Sight-Grid Signal Mirror

Coghlan's Sight-Grid mirror offers a larger aiming grid pattern for easier targeting. Glass construction provides a brighter flash than polycarbonate. Heavier but optically superior. A solid choice if weight isn't the primary concern.

UST StarFlash Mirror
Value Pick

UST

StarFlash Mirror

The UST StarFlash is a compact, lightweight mirror with a built-in aiming star. Floats in water and comes with a lanyard. The most packable option for ultralight kits and lifejacket pockets.

Waterproof Pen

โ†‘
Fisher Space Pen Bullet

Fisher Space Pen Bullet

Lifetime

The Fisher Space Pen Bullet uses a pressurized ink cartridge that writes in any orientation โ€” upside down, in zero gravity, underwater, in extreme cold (-30ยฐF) and extreme heat (250ยฐF), and on wet or greasy surfaces. The sealed cartridge prevents ink from drying out for decades. The compact bullet form factor is smaller than a closed pen, expanding to full size when posted.

What owners say: Owners report carrying the same Space Pen for 10+ years. The pressurized cartridge never dries out, even after months of non-use. The brass construction develops a patina over time. Refills are widely available and last for approximately 12,000 feet of writing.

Watch for: The compact size is easy to lose โ€” attach a lanyard or keep it in a dedicated pocket. The pressurized cartridge produces a slightly thicker line than standard ballpoints. The chrome finish shows scratches quickly; the matte black version hides wear better.

Alternatives Worth Considering
Rite in the Rain All-Weather Pen
Also Great

Rite in the Rain

All-Weather Pen

Rite in the Rain's dedicated all-weather pen is optimized for their paper โ€” the ink formula is designed to resist water smearing on all-weather paper specifically. Click-action mechanism, pocket clip, and a bold black line. The purpose-built companion to Rite in the Rain notebooks.

Zebra F-701 Stainless Steel
Value Pick

Zebra

F-701 Stainless Steel

The Zebra F-701 is an all-stainless-steel ballpoint pen with a knurled grip that writes reliably in most conditions. Not pressurized like the Fisher, but the stainless construction is nearly indestructible. The most durable everyday pen at under $10.
