What are people saying about the Garmin Striker 4 Fish Finder?
Great unit, would recommend!
The Garmin Striker 4 is a great fish finder and GPS that I would highly recommend for boaters who travel. I recently used it for the first time on a 10 mile canoe trip, and I couldn’t be happier with its performance. I was able to plot my course on a paper map to get the coordinates of each leg, and then add all the waypoint coordinates into the unit the night before creating a route.
The next day on the water, the GPS unit kept track of where I was, how long it would take to get to the next waypoint, and how long it would take to get to the final destination. It also told us our speed, which is very valuable for trip planning.
I have two boats I use, one is a rowboat for fishing where I mounted the transducer on the electric motor propeller, and a canoe where I mounted the sensor in the hull using a foam mounting piece. In both cases, the fish finder worked well, and I love that I can swap the unit between the two. Note that I use velcro to make the group swappable between the boats, but permanently mounting it would not be hard at all. The base is very friendly, and you can adjust it to face any direction.
During our trip, we were rained on, and the Garmin had no problems in the rain. It held up very well.
If you just need a fish finder for local lakes and you’re not traveling in your boat, and you don’t need to use waypoints, this is probably overkilling. But if you’re looking for a great GPS and fishfinder in one, this is a fantastic unit, and I highly recommend it.
A quick note about my setup, I built a battery box to power my charger, but I know there are nice little battery boxes premade available that might be more hardy and compact than the one I built. You will need to explore power options and be able to wire the unit to whatever power source you choose. I like that flexibility.

Compact Design!
I got this for my Kayak.
It is the easiest to use the electronic device I have bought in a long time.
The menu and scroll are simple to navigate the display is easy to see (I am old with bad eyes) and the screen is big enough to see.
I mounted it about 3 feet in front of me and had no problem wit vision sound or changing features even in the wind and currents.
It is also waterproof if you grease the Battery compartment door, The screws on the Battery door are captive so you won’t lose them.
Battery life seems good as I only had it out for 1 day and used under 1/2 life and that includes the time playing with it when it got here.

What are people saying about this LUCKY Fish Finder?
Glad I found this product!
This is actually a really cool thing to have when your fishing off the bank or dock. I was throwing lures left and right and wasn’t catching anything. Put the castable wireless monitor on my line and cast it out in several areas only to realize there wasn’t a fish to be found. Good to know so you can find a new fishing spot!
The range seems more than reasonable and picks up fish as far as I could cast my line. I love knowing the depth information, water temp, and whether the fish are on the bottom or upper water columns. I plan on using the wired version for my kayak.
The portable display is much nicer than using my phone. I don’t want to kill my phone battery and the portable screen lasts way longer on a single charge than I even need to use it for. If your looking for a decent fish finder, that can also be cast, then look no further. This is well worth the investment.

Handheld, Portable Fish Finder FAQs
How Does a Portable Fish Finder Work?
Portable fish finders use sonar technology to detect fish. The transducer emits sound waves and if there’s an object in their way, the waves will hit it and bounce back. When those waves reach the transducer, the software calculates how far away the object is. It does this by analyzing how many seconds it took for the waves to bounce back from the obstacle. The beauty of some of these fish finders is that you can cast the transducer when fishing from shore.
Luckily, you don’t have to worry about doing any math. The fish scanner does that for you. On the screen, you’ll see how deep the fish are based on the readings the transducer did. If there are quite a lot of obstacles in the way of the device, you can pretty much deduce it’s the right spot for fishing.
Do Portable Fish Finders Work?
Yes, portable fish finders do work. The higher-end models can detect small fish with a lot of precision. They can also tell a rock or bank of sand from a school of fish, so you’re never induced in error. The cheaper models will still accurately tell you where fish are. Yet, they’re not as sensitive as other items and will only be able to detect medium-sized fish (larger than 10 centimeters).
Who Should Get a Fish Finder?
Anglers and fishing fans can benefit a lot from getting one of these devices. For starters, fish finders lead you to the right fishing spots. Pick an area of the lake or shore that’s home to a more significant amount of fish—no more waiting for hours for something to bite.
How Do You Use a Portable Fish Finder?
Technology can be a bit daunting, but in this particular case, it doesn’t have to be. All models are different and give you the readings in different ways. Despite that, to use most fish scanners what you have to do is:
- Turn on the scanner and, if it applies, pair it with your smartphone.
- Adjust the settings to your preferences.
- Cast the fishing line into the water with the transducer attached.
- Keep an eye on the screen and wait for fish to show on the screen.
Step four is where the models diverge. Some will show red-and-yellow botches to tell you there are fish nearby. Others will only show the icon of a fish at the depth they’re at. That’s why it’s useful to read the instructions manual when you get your gadget. All in all, the screen shouldn’t be hard to read.
Where Can You Use a Handheld, Portable Fish Finder?
You can use a portable fish finder pretty much anywhere you can fish. Lakes, off a quiet beach, slow streams, you name it. Just beware of waves and suspended particles. These will throw off the readings and make them inaccurate.
Ice Fishing
You can go ice fishing with a portable fish scanner. After all, wouldn’t it be great if the hole you drill in the ice sheet is near a school of fish?
There are two ways you can go about using the scanner. The first is by cutting a separate hole for the fish finder and checking to see if it’s in a good area. If it is, go ahead and drill another hole next to it for your fishing line. The second way is by clearing snow piled on top of the ice sheet, making sure there are no cracks or bubbles in the ice, and placing the scanner here. If your sonar tells you that’s a good place to cut a hole, go ahead and do that. While the readings may not be as accurate with some models in this situation, it’s the most hassle-free way of scouring for a good fishing spot.
Kayak Fishing
This is one of the most popular uses for portable scanners. Yet, it can get a little tricky with installation—and not all devices will work on a kayak.
First, make sure your fish scanner uses either rechargeable or disposable batteries. If so, great! Some models need to be plugged into a 12-volt battery, like that of a boat or car. With those, you won’t be able to go kayak fishing.
Second, find a way to mount the scanner on the kayak. Larger, clunkier models may come with suction cups at the bottom that you can attach to the front of the kayak. You could also find a spot on the floor of the kayak to set up your fishfinder. Alternatively, if you’re using a scanner that sends the readings to your phone, you could attach your phone to the fishing pole. There are ways of making this less precarious. For instance, you could get a phone mount and fix it securely in place on the pole.
Sea Fishing
An obvious use for these portable scanners is sea fishing. When you go out on a boat, there’s plenty of room to set up the scanner: on the side of the boat, on one of the seats, on the floor—get creative. You’ll just have to watch out for waves. These interfere with the accuracy of the transducer readings, leaving you with a bad reading. But if the sea is calm, it’s a great place to use your new device.
Saltwater Fishing
You may be concerned about how accurate your sonar’s readings are in saltwater. Don’t be. Most portable fish finders are adapted for both freshwater and saltwater fishing.
Underwater Fishing
Portable fish finders are used to get a clear picture of what’s happening below the surface. They’re your second pair of eyes, only adapted to seeing underwater. As useful and handy as they are, they’re no good for underwater fishing. After all, you would be using your own eyes to find your next catch.
