Smart Fish Finder

Connected Catch

In the game of man vs. fish, man now has an incredible advantage. Deeper is a light, portable fish finder, ready to deliver details on the waters below straight to your smartphone or tablet.

Simply cast Deeper out on the water to get an instant diagram of the depth, waterbed contour, the size and location of fish, and the water
temperature, too. Merely the size of a tennis ball, Deeper works whether you’re fishing on a boat, on a bridge, or from shore. It even shows items like alligators, abandoned cars, or whatever else might be below.

Founders Aurelijus Liubinas and Rolandas Sereika are Lithuanian nationals who went on a fishing trip to Finland. They asked the locals for the best fishing spot, but couldn’t find it. Not wanting that to happen again, they took two years developing Deeper.

Rechargeable from a car or any USB port, Deeper is easy to bring anywhere. Easily connect it to iOS and Android devices via the free Deeper app, which is filled with features any angler will appreciate. With Deeper, the fisherman in your life will see the sport in a new, smarter light.

    Good Afternoon, I just returned from a fishing lunch and made it back just in time, so hopefully some of you would like to chat about the Deeper Fishfinder! Please let me know!

    @Ual How long is the battery life? How does it charge? USB?

    I was just wondering what happens if line breaks. Does it float

    @David If the line breaks, the Deeper floats! It hasn't happened yet, but when I'm bank fishing, I use a 30lb test on the line I'm using to cast the Deeper.

    @Ual Ross, the battery usually lasts up to four hours and recharges in about 30-45 minutes. You can recharge it using your car with the car charger that's included in the package.

    @David . It appears to float. I don't think it would as effective if it sank. There is a frame in the video that looks like it is floating.

    @Joseph Correct, it floats, and just as importantly, there are two attachable tackle attachments that I use to double rig my fishing line to it. I usually use an old fishing pole and 30lb test to cast the Deeper and keep it in the water for constant results. That way I can fish with my favorite pole and always know the fish activity where I'm fishing.

    Does the Deeper float on the surface of the water or does it sink to a specific depth? How is this different than a normal fish finder that can either be attached to a boat? What is the diameter of the Deeper field of vision?

    @Mike It floats on the surface and has sonar on the bottom of the deeper to scan down and in about a 30 yard radius around it. It's incredible.

    Hi. It looks like a really neat product. Would it work well trolling a coastline to get a more complete picture of a fishing area? How does it compare to a boat's traditional, permanently mounted fish finder? Do you use both in conjunction with each other, or would you recommend one over the other depending on the type of fishing you are doing? Thanks for your time. Good luck with your product.

    @Thomas Yes, one of my business partners, Juan, has a big boat and uses it to troll, as his boat fish finder only charts the area around the boat. No fish has eaten it yet! It works great for trolling, and I use it when I cast into areas where my canoe won't go. Down here in Miami, we have a lot of alligators and crocodiles, so I always keep watch they don't think the Deeper is food..

    @Ual How deep will it work? I fish in the ocean, where the depths can approach 100 feet. Will it work in water that deep?

    @John The Deeper works up to 150 feet underwater. It is very accurate

    How exciting!! I'll have to save for at least a year before I can buy one, but my brother & sister-in-law are avid fisherpeople -- they live in Hawaii and I think their worse fear would be that the marlin and other big fish would eat the gizzmo. I on the other hand, am a trout angler. I have tons of family in Minnesota where there are tons of lakes where my cousins fish too. As you can see, once I buy mine and take it with me to the streams & lakes, ALL of them will want one. I'm saving!! I'm saving!! ;-)

    @KL Hi KL, I do more freshwater than my business partner, who only does saltwater fishing, so I'm with you on the trout fishing. Up in Minnesota, they have some big freshwater fish! Hopefully you won't have to save all year before you can buy one, and you can feel free to call me to discuss. We're here to help. (786) 469-7109 is our office telephone and (800) 819-1757 toll free. And it's true, everyone that notices wherever I fish wants one too (you know everyone has their own private fishing spot and techniques, so it seems few want to share their favorite places or Deeper fish locations.

    It looks and sounds like a great idea,Now all that's needed is too make it inexpensive enough for the people to afford it! The people who really need it is not the guy with a big fancy boat,or money to burn,but the little guy,who is on a fixed income,who fishes for food for family,when he goes fishing,I believe it would help them most. Can a less expensive model be made. My $1200.oo a month disabilty $ only go so far,and I love to fish when I can.

    @Dennis Hi Dennis, I share your concern and we're working with Friday Lab to do just that. It's a new product with state-of-the-art sonar, so it's kind of like putting big boat sonar in a small smart device. We'll continue to work with Friday Lab to improve the product and make this new technology more affordable for everyone.

    Great looking product, very interested in getting one.

    You went on a fishing lunch, what did you catch ?

    Best regards

    @Michael Not a thing, Michael! I only had 45 minutes, but there's a huge lake about 10 minutes away that I haven't fished yet and I wanted to know if there were any prospects. I found a bunch right under the shifty dock where I wasn't thinking there were any fish! We have lots of largemouth bass here, but I'm a huge fan of Peacock Bass, and they bite all day long!

    My buddy and I have been looking for a couple of cool products to try out for our local area sportsman page and this looks like the perfect thing. Freshwater and saltwater fishing is huge here and this looks awesome!

    @Matt Thanks, Matt, I fish weekly with my son and grandson and we use the Deeper. My grandson loves the digital telephone sonar stuff, probably more than actually fishing for the fish! We canoe and bank fish, mostly, here and in the Keys. I was sold on it before we became national distributors, and it fishes as hard as we do. With kids, finding the fish fast makes for a more enjoyable experience than fishing and waiting, like we used to do. Let me know how you like it!

    We do a lot of ice fishing here in northern Iowa/southern Minnesota, is the deeper able to handle freezing temperatures?

    Hi Jeff,

    Great question. The comment board closed just before Ual could provide this answer on Friday but here it is:

    Yes, the Deeper Fishfinder works in the winter and under icy conditions. Ice fishermen use it and have had the same results. Depending on the wind chill, the battery charge may require recharging after about two hours, but otherwise it works fine. Ice fishermen have advised that one needs to keep the metallic sonar sensors on the bottom of the Deeper free of ice periodically.
