Buying Guide: How to Pick the Right GPS Handheld for Fishing and Boating
I spend a lot of time on the water, and I can tell you that a good handheld GPS is as essential as a life jacket. It’s not just about knowing where you are; it’s about finding your way back to that secret fishing spot or navigating safely through fog. With so many options for GPS handhelds for fishing and boating, choosing one can feel overwhelming. Let me break down what I look for.
First, consider the display. You’re going to be using this in bright sunlight, so you need a screen that is easy to read. I always look for a high-resolution, sunlight-readable display. Touchscreens are great for quick navigation, but physical buttons are a lifesaver when your hands are wet or you’re wearing gloves. Think about the conditions you’ll face most often.
Next up is battery life. This is a big one. There’s nothing worse than your unit dying halfway through a long day. Some models use standard AA batteries, which is great because you can pack spares. Others have built-in rechargeable batteries. I prefer units that offer both options, giving me flexibility. Look for a device that promises at least 16 hours of continuous use, but remember, using backlights and tracking lots of data will drain it faster.
For anglers, preloaded maps are a game-changer. You want a device that comes with detailed charts, including depth contours, navigational aids, and maybe even satellite imagery. Being able to mark waypoints for productive spots is a core feature. Some advanced units even support LakeMaster or BlueChart maps, which provide incredibly detailed bathymetric data. For boaters, having accurate coastal charts and tide information is non-negotiable for safety.
Durability is another critical factor. Your gear gets knocked around on a boat. I only consider units that are waterproof, not just water-resistant. The IPX7 rating is a good standard, meaning it can survive being submerged in a meter of water for 30 minutes. A rugged, rubberized body that can handle a drop is also important.
Finally, think about the extra features. Bluetooth connectivity can be handy for receiving smartphone notifications or connecting to an autopilot system. A built-in altimeter and barometer can help you keep an eye on the weather. Some even include a camera to geo-tag your photos. While these are nice, I always prioritize a bright screen, long battery life, and accurate GPS reception above all else. Getting these basics right will ensure your device is a trusted companion on the water.
FAQ
What makes a fishing GPS different from a regular handheld GPS?
A regular handheld GPS is great for telling you your latitude and longitude on a trail. A fishing-specific model is built for the water. It usually comes preloaded with detailed marine charts that show water depths, underwater structures, and navigation markers. It also allows you to easily mark waypoints for fishing holes and often has features for tracking trolling paths. When you’re looking at GPS handhelds for fishing and boating, you’re getting a tool designed specifically for aquatic environments, not just land.
How important is waterproofing for a handheld GPS unit?
In my opinion, it’s absolutely essential. You’re on a boat, near water constantly. Splashes, rain, and the occasional wave are inevitable. I would not take a unit onto my boat that isn’t rated as waterproof. Look for an IPX7 or IPX8 rating. This means the device can be submerged in water for a period of time without being damaged. Water-resistant is not enough; you need the peace of mind that comes with a truly waterproof device.
Can I use my smartphone’s GPS app instead of a dedicated unit?
You can, but I don’t recommend relying on it as your primary navigation tool. Phone GPS apps are fantastic for casual use, but they drain your phone’s battery incredibly fast. Your phone also isn’t built to be waterproof or withstand harsh marine conditions. Most importantly, cellular service is often non-existent offshore or on large lakes. A dedicated handheld GPS uses satellite signals, so it works anywhere, has a much longer battery life, and is built to be rugged.
What does “preloaded maps” mean, and do I need them?
Preloaded maps mean the device comes with detailed maps already installed on its internal memory. For boating and fishing, this is a huge time-saver and a feature I always look for. Instead of seeing a blank screen with a dot showing your location, you see a full chart with coastlines, depths, buoys, and points of interest. Without preloaded maps, you’d have to buy and download them separately, which can be a hassle. It’s worth paying a little more upfront to have them ready to go out of the box.
How long does the battery typically last on these devices?
Battery life varies a lot depending on the model and how you use it. With the screen brightness on high and tracking enabled, you might get 10-12 hours. Under more conservative settings, some units can last over 20 hours. Many models use standard AA batteries, which I prefer because I can always carry a spare set. If it has a built-in battery, I make sure it’s fully charged before every trip and consider a portable power bank as a backup.
