Your GPS device is your trusted guide, whether you’re conquering a muddy trail, navigating whitewater rapids, or just caught in a surprise downpour. But water is the kryptonite of electronics. A single dunk or persistent drizzle can turn your high-tech navigator into a very expensive paperweight.
Fear not, adventurer! Protecting your device isn’t as hard as you might think. It boils down to knowing your device’s limits and using the right gear. Let’s dive into the how-to of keeping your GPS high and dry.
Step 1: Know Your Enemy (and Your Armor) – Understanding IP Ratings
Before you do anything, you need to know what you’re working with. That little “IP67” or “IPX8” on the spec sheet is your best friend. It’s called an Ingress Protection (IP) Code, and it tells you exactly how well your device is sealed against solids (like dust) and liquids (like water).
The IP rating system was developed by the International Electrotechnical Commission (IEC) and is standardized under IEC 60529, first published in 1976. This international standard provides users with more detailed information than vague marketing terms such as “waterproof” or “water-resistant.” The IP code consists of two digits: the first indicates protection against solid particles (rated 0-6), and the second indicates protection against liquids (rated 0-9).
Understanding the Second Digit: Your Water Protection Guide
The second digit is the one we care about for waterproofing:
IPX4: Basic splash protection. The device can withstand water splashing from any direction for at least 5 minutes. Perfect for light rain or accidental splashes, but don’t push your luck.
IPX5: Protected against low-pressure water jets (6.3mm nozzle) from any direction. Testing involves projecting 12.5 liters of water per minute for at least 15 minutes at 30 kPa pressure from 3 meters away. Suitable for moderate rain and water spray.
IPX6: Protected against high-pressure water jets (12.5mm nozzle). Testing requires 100 liters per minute at 100 kPa pressure from 3 meters for at least 3 minutes. However, it’s crucial to note that passing an immersion test (IPX7/8) does not automatically mean the product also passes jet-spray tests unless both ratings are declared (e.g., IP66/IP68).
IPX7: The workhorse of water resistance. A device with this rating can be submerged in up to 1 meter (about 3.3 feet) of water for up to 30 minutes. Perfect for rain, splashes, and accidental drops in a puddle. GPS trackers rated IPX7 are fine for cars, bikes, and pets exposed to rain and puddles.
IPX8: A step up from IPX7. It can handle being submerged deeper than 1 meter, but the exact depth and time are set by the manufacturer (e.g., 2 meters for 60 minutes). This is what you want for kayaking, fishing, or serious water sports. The IP68 rating has an important caveat: it doesn’t specify exactly how long or at which depth an enclosure must keep water out—only that the conditions must be agreed upon by the manufacturer and buyer. Some devices with IP68 ratings can be submerged up to 1.5 meters for 30 minutes, while others may withstand greater depths.
IP68: The gold standard. The “6” means it’s completely dust-tight (no dust ingress whatsoever), and the “8” means it’s protected against prolonged immersion beyond 1 meter. You’ll see this on high-end handhelds and smartphones. According to recent testing data, IP68-rated devices are deemed “dust-tight” and can typically be submerged in more than one meter of water for a certain period, usually 30 minutes, though manufacturer specifications vary.
IP69/IP69K: The ultimate protection level. Originally developed for road vehicles requiring intensive cleaning (dump trucks, concrete mixers), IP69K represents the highest protection against dust and high-pressure water jets. The test involves 80°C (176°F) water at 8-10 MPa (80-100 bar; 1,200-1,500 psi) with a flow rate of 14-16 liters per minute. The nozzle is held 10-15 cm from the device at angles of 0°, 30°, 60°, and 90° for 30 seconds each. This rating is common in food processing, agriculture, automotive, and industrial manufacturing industries.
The Reality Check: What IP Ratings Don’t Tell You
These ratings are for static, fresh water under controlled laboratory conditions. They don’t account for several critical factors:
- High-pressure water jets: Like from a power washer or aggressive car wash systems
- Saltwater corrosion: Marine environments are significantly more corrosive than the fresh water used in testing
- Wear and tear over time: An old device with a great IP rating might not be as resilient as it once was. Factors such as drops, exposure to chemicals like chlorine or sunscreen, and UV radiation can gradually degrade seals and materials
- Temperature extremes: Testing is typically conducted at moderate temperatures
- Movement at high speeds: Such as being strapped to a speeding jet ski or motorcycle
- Chemical exposure: Pool chlorine, cleaning agents, or saltwater can be more damaging than plain water
It’s essential to consider that IP ratings apply only to fresh water. Saltwater and chlorinated pool water require thorough cleaning after exposure to prevent seal degradation.
Step 2: The First Line of Defense – Proactive Protection
You don’t have to rely on the factory seal alone. A few simple habits can dramatically increase your device’s lifespan and maintain the integrity of its waterproof protection.
Seal the Ports: Your Device’s Achilles’ Heel
The charging/data port is the biggest vulnerability in any GPS device. Always, always make sure the rubber sealing flap is completely closed and free of dirt, sand, or lint. A tiny grain of sand can prevent a perfect seal and compromise the entire waterproof system. Before each outdoor adventure, perform a quick inspection:
- Check for debris around the seal
- Ensure the rubber flap sits flush against the device
- Press gently to confirm it’s completely closed
- Look for any signs of wear, cracking, or deformation in the rubber
Keep it Clean: Maintenance is Prevention
After exposure to saltwater or sand, rinse your device with fresh, clean water and dry it thoroughly with a soft cloth. This simple step is crucial because:
- Salt is highly corrosive and can degrade seals over time, even on IP68-rated devices
- Sand particles can lodge in seal grooves and create tiny gaps
- Chlorine from swimming pools can damage rubber gaskets
- Dirt accumulation can prevent proper seal closure
Professional divers and marine equipment users follow a strict cleaning protocol: rinse immediately after use, dry with a lint-free cloth, and inspect seals before storage.
Avoid Extreme Temperatures: Heat is the Enemy
Don’t leave your GPS on your dashboard in blazing heat. High temperatures can cause the internal components to expand and contract, potentially compromising the waterproof seals. Similarly:
- Rapid temperature changes (hot to cold) can cause condensation inside the device
- Extreme cold can make rubber seals brittle and less pliable
- Most devices have an operational temperature range of -4°F to 176°F (-20°C to 80°C)
- Store devices in moderate temperatures when not in use
Pressure is the Enemy: Understanding Immersion vs. Jets
Remember, IP ratings are for immersion, not for being blasted by a jet of water. The distinction is critical: a device rated IP67 (submersion to 1 meter) may fail when exposed to high-pressure jets. Avoid:
- Using high-pressure hoses or car wash systems directly on your device
- Submerging while moving at high speed (pressure increases with velocity)
- Exposing to aggressive water jets during cleaning
- Placing near outboard motor wash or jet ski spray
According to IEC 60529 testing standards, water ratings aren’t cumulative beyond IPX6. Passing an immersion test does not automatically mean the product also passes jet-spray tests unless both are declared.
Step 3: Gear Up! – Waterproof Cases and Bags
So, what if your GPS isn’t waterproof, or you’re heading into conditions that push the limits of its rating? This is where you bring in the reinforcements.

Step 4: The DIY “Insurance Policy” – Silicone Grease
For the tech-savvy and cautious, a tiny bit of silicone grease (the plumber’s kind, often used for scuba gear O-rings) can work wonders. This is an advanced tip, so proceed with caution.
How It Works: The Science of Seal Maintenance
Apply a very thin film of 100% silicone grease to the rubber sealing gasket of your device’s battery/port cover. This maintenance practice is standard in professional diving and underwater photography communities. Here’s why it works:
- Keeps rubber pliable: Prevents the rubber from drying out, cracking, or becoming brittle over time
- Creates a better seal: Reduces friction during installation and helps the O-ring seat properly
- Prevents degradation: Protects against atmospheric degradation and extends seal lifespan
- Water resistance: Provides additional water repellency and prevents moisture damage
Professional-Grade Products
Super Lube Silicone O-Ring Grease: Specially formulated non-curing silicone compound designed for lubricating, sealing, and conditioning O-rings. Features:
- Wide operating range: -40°F to 500°F (-40°C to 260°C)
- Excellent water and moisture protection
- PFAS-free formula
- Protects O-rings from damage by abrasion, pinching, or cutting
- NSF-61 certified for use in potable water systems
GEAR AID Silicone Grease: Food-grade (non-edible) silicone lubricant specially formulated to permeate rubber surfaces deeply. Used extensively by divers to maintain O-rings, valve systems, and regulator components on all dive gear, underwater cameras, waterproof dive lights, and pressure systems.
Critical Application Guidelines: A HUGE Warning
Less is more! You want a barely-there film—about the size of a grain of rice for the entire O-ring. Here’s the proper technique:
- Remove the O-ring from its groove: Always take it out to avoid silicone build-up inside the groove
- Inspect thoroughly: Check for debris, damage, cracks, or signs of wear before greasing
- Apply sparingly: Use a very small amount (grain of rice size)
- Spread evenly: Distribute across the entire surface until the O-ring becomes slightly glossy
- Wipe excess: Remove any excess that could attract debris
- Never contaminate contacts: Keep grease away from electrical contacts and charging ports
What Can Go Wrong:
- Too much grease attracts dirt and grime, which can break the seal
- Grease on electrical contacts can cause connection failures
- Using petroleum-based products instead of silicone can degrade rubber O-rings
- Excessive application can cause leaks rather than prevent them
Understanding Silicone Grease Limitations
It’s crucial to understand that silicone grease does not function as a sealant itself. This is a common misconception in the diving and waterproof equipment community. Rather, the primary purpose of silicone grease is to reduce friction during installation and use of O-rings.
Silicone grease cannot:
- Compensate for damaged or improperly installed O-rings
- Repair existing leaks or cracks
- Replace worn-out seals
- Provide waterproofing on its own
Regular inspection and maintenance of O-rings are paramount to ensure reliable performance. The grease is a maintenance tool, not a fix-it solution.
