LUCKY’s hand-held portable fish finder offers many features for the inflatable pontoon boat fisherman. One caution, however, is that this is the only device on this list that doesn’t appear to have any compatible device manufactured to mount it to your boat.

Though it has among the smallest screens on this list, it does include a fish finder but with a TFT LCD color display.

It can display underwater contour, depth, and even water temperature and fish. Unlike other units, however, it simply puts a few cartoon fish on your screen rather than a SONAR image of what the fish may actually look like.

This model works well for any type of fishing, from ice fishing to deep-sea fishing, to fishing from the shore or an inflatable pontoon boat.

Inflatable Pontoon Boat Fish Finder Buying Considerations

Whether you decide to buy a pontoon boat or not, a fish finder is beneficial for any type of fisher, though because of how much they cost, you have to get it right. The experienced inflatable pontoon boat fisherman should consider a number of factors before purchasing any of the models on this list.

Type of Water

First and foremost, you must consider the type of water you are fishing in. If you are fishing in open seas, you definitely want a model with much deeper SONAR depth than some of those offered on this list. If you fish in shallow rivers or lakes, you may wish to sacrifice depth for detailed display.


Remember, too, that there are vast differences between the details offered on these displays. Some actually show you the contours of the fish under the water. Some, however do not. They just put a cartoon fish on the screen and you have to hope that the SONAR really spotted a fish and not a floating shoe.


You’ll also want to consider how important route mapping, GPS, and marking spots and saving them for another trip are to you. Two of these models offer all of that. Some offer only GPS. If you want to remember exactly where your favorite fishing hole is and have your fish finder take you there, then you may need to consider one of the Garmin models with their proprietary technology.

Water Rated

Interestingly, only a few of these devices actually tell you, the inflatable pontoon boat fisherman to what degree the devices are water rated. Remember that the better the water-rating, the more waste-resistant the device is. If you frequently take your inflatable pontoon boat in the surf or for deep-sea fishing, that water rating is far more important than if you are in a typically still lake.


Consider, too, whether or not the device you are purchasing has a warranty. For an inflatable pontoon boat fisherman, a fish finder is a serious investment.

Make sure that your investment is protected. If the manufacturer doesn’t offer a warranty, you may want to consider whether your boat insurance will cover the device, or if you can buy a third-party warranty.


A high-quality fish finder will make the difference between a fish fry after your day on your inflatable pontoon boat and eating at the nearest fast-food restaurant, so choose wisely.

Too, remember to make sure you are selecting the very best model that fits the places and manner in which you fish. Don’t be wowed by proprietary technologies or big displays if you feel another model can best suit your needs.
