Jet skis can be some of the best watercraft for fishing, allowing you to get in tight places or shallow water. If you’ve already installed a fishing rack, then your next project should be a jet ski fish finder! If you already have one, then check out some other essential jet ski fishing accessories.
Jet skis typically do not come with fish finders (except this See Doo Fish Pro). More expensive jet ski models occasionally have GPS, but if you really want to make your jet ski a true fishing vessel, you will need to get your hands dirty and mount the transducer to the hull (or in it) yourself. Luckily, it can be pretty easy with the right tools.
When looking for a fish finder for waverunners, size is one of the most important factors. A typical fish finder for a boat will be too big to mount on your steering system. The 5 best jet ski fish finders with GPS are:
1. Lowrance HOOK2 5 Fish Finder
2. Garmin Striker 4
3. Lowrance HOOK2 4x GPS Fish Finder
4. Garmin Striker 4cv GPS Fishfinder
5. Garmin echoMAP CHIRP 53cv
We will tell you why these are the best waverunner fish finders later in this article!

How to Install a Jet Ski Fish Finder
To install a jet ski fish finder, you will need to install a transducer mount to the hull. You can then install a RAM mount to the dash or steering system. Depending on your model, you may be able to find holes to run the transducer cable, otherwise, you will likely have to drill a hole for the cable in the hull.
If you do not want/need water temperature readings, you can place the transducer inside the hull. This would prevent drilling into your hull. Some people also opt to use silicone caulk, but this is a less secure option.
Choosing The Right Fish Finder
When choosing a jet ski fish finder, you should keep your intentions in mind. Whether you plan on fishing in deep water or shallow water can make a huge difference! All fish finders use different technology designed for specific needs.
Low-frequency devices are best for deep water, as the sonar can travel further. High-frequency devices provide the best accuracy and picture quality, but they are best used in shallow water. If you are just fishing for fun, a high-frequency device is the best bet. It will still work in deep water, but the readings will not be as accurate as a low-frequency device. If you are a serious fisherman, a low-frequency device is your best bet if you plan on deepwater fishing.
Wattage also plays an important role for accurate readings. If you are a serious fisherman, then higher wattage is crucial for accurate readings in deep water. If you are fishing for fun mostly, then lower wattage devices will do the trick – it just might produce a fuzzier display.
