Fly Fishing with Drones the New SwellPro Splash Drone 4

Drones are everywhere. They are being used for everything from surveillance to delivery and yes, they are even being used for fishing. The new SwellPro Splash Drone 4 is the most recent entry into the “fishing drone” market. Designed from the ground up as a true “fishing” drone and 100% waterproof. I thought we might take a look and see what’s new and how it compares to their SwellPro Splash Drone 3.

The popularity and number of drones continues to increase, with around 7 million units expected to be sold in the US this year. From flying for recreation to aerial photography, unmanned aerial systems (UAS) are increasing due to lower prices and improving technology. From a fishing standpoint, it’s not enough that drones have great camera power or fantastic range; they need to be waterproof and have the ability to fly in any weather. Currently the most popular and capable fishing drones are made by Gannett and SwellPro. I have reviewed the Gannett Pro Plus drone and the SwellPro Splash Drone 3 previously.

The new SwellPro Splash Drone 4 is a great fishing drone. Both the drone, and the controller, are 100% waterproof and saltwater/corrosion resistant. With a heavier payload capacity, multiple camera options, new SwellPro Navifly App, built in GPS, boat mode, and if it does end up in the water, self-righting feature make the SwellPro Splash Drone 4 not only a great fishing drone, but a complete multi-purpose drone. I give it an overall rating of 90 out of 100 with it being an expensive piece of equipment and payload capacity is limited to 2Kg.

“Fly” Fishing with Drones

Fishing with drones is a specialized sport. It takes some time to learn to fly the drones and some special rigging and fishing gear to adapt to “fly” fishing with a drone. One thing is for sure, you can reach waters that you never could hope to reach simply by casting your baits. The Land based shark fishing community is rapidly adapting to using drones for bait deployment over the more traditional kayak method. When selecting a fishing drone, there are some important features to consider.

1.) Is it really Waterproof? – Fishing involves water, and water and electronics don’t like each other. There is always a chance that your drone could end up going for a swim when fishing and you need one that can survive getting wet.

2.) Payload Capacity – You will be hauling baits, weights and tackle with your drone so you need to make sure the drone can handle the weight and still deploy your bait and return safely.

3.) Battery Life – Drones use batteries. Drones under a load use batteries at a faster rate. A fishing drone needs to have the battery life to deploy multiple baits offshore sometimes several hundreds of yards offshore. At the very least, you need good rechargeable batteries that are quick and easy to switch out.

Batteries are one of the most vital parts of any drone and knowing how much power they can store and use will determine how long you can operate them and how many baits you can deploy before you need to change or recharge your batteries. You need to consider that flying your drone in wet and or windy weather uses up power. Water can accumulate on propellers which is extra weight that uses energy and drains your battery at a faster rate. So, battery life, ease of recharging and switching are extremely important to consider when choosing a fishing drone.

Now, most fishing drones are marketed as waterproof. However, are they really waterproof, or just water-resistant drones? It makes a big difference, particularly if your drone goes for a swim. A water resistant drone may not do well and the manufacturer may not want to service it under warranty. Read the fine print and make sure you are using a 100% waterproof drone. Check the controller as well and make sure it is waterproof.

If you get caught in the rain, you don’t want to short circuit your controller. Another consideration is saltwater. Some drones are waterproof, but not corrosion resistant. Saltwater is very tough on gear in general, but metallic parts in particular. So, if you will be drone fishing in saltwater, check for saltwater resistant models. The SwellPro Splash drone 4 has been designed from the ground up as fishing drone that is 100% waterproof and saltwater resistant.

SwellPro has been making the only waterproof drones dedicated for fishing like the SplashDrone series since 2015. Integrated with an interference-free payload release mechanism, SwellPro’s fishing drones can easily and safely fly the line far out, then drop baits to fish-rich areas that are out of normal casting range in just a few minutes. The end benefit is drastically increasing the success of catching more fish or bigger monster based on the shore.

In 2013 Eric Hu, the founder of SwellPro, came up with the idea for a waterproof drone after witnessing a very expensive drone crash into the ocean while he was vacationing in the Caribbean. With his back ground in waterproof cameras and hobby planes, he threw himself into the brand new drone industry with passion. From this unfortunate accident, SwellPro was born to make waterproof drones a reality.

There were many technical challenges in the beginning. Just making the drone fuselage waterproof was not enough, as heat build up and the requirements of flight sensors had to be resolved. But, after much hard work, Swellpro is now proud to hold numerous patents related to the waterproof drone concept.

One of the earliest breakthroughs was the waterproof gimbal to carry a go pro camera. Today Swellpro makes a series of waterproof drones and accessories in their own manufacturing facilities.Swellpro’s in house research and development team continues to develop new products and technologies to bring innovative waterproof products to the industry. SwellPro’s fishing drones have been tested and trusted by over 10,000 anglers all over the world. Now introducing the all new SwellPro Splash Drone 4.

SwellPro Splash Drone 4 Final Verdict

The new SwellPro Splash Drone 4 is great piece of equipment. They have made numerous improvements from the Spash Drone 3. Including making the controller waterproof for true all weather operations. Increased payload capacity, and improvements in battery life and changing out batteries. At 2KG load capacity, it will still be limited for some of the larger shark bait applications, but for most of your fishing needs it will be more that adequate. I give it an overall rating of 96 out of 100. The only drawbacks, for me, are the load capacity and the price makes it on the higher end for fishing drones. It does come with a14-day money back guarantee and 1-year warranty.
