Love at first cast. The fishfinder that syncs
with your smart phone or tablet.

From your first cast, there’s a lot to love about iBobber™.

You’ll love that it syncs via Bluetooth Smart® with your iPhone or iPad or phone or tablet for Android™ up to 100’ away, so you have a fishfinder that’s as mobile as you are.

iBobber uses sophisticated sonar to locate fish down to 135’, with 2 fish sizes, while the intuitive app enables you to GPS tag favorite hotspots, map waterbed contours, and measures water temperature.

And you’ll love that you can save details of all your fishing adventures with the Trip Log, and share it all on social media. You’ll also love the Lunar Calendar, Fish and Strike Alarm, LED Beacon, Weather sync, and stunning graphics. 

The love gets even deeper when you see how simple iBobber is to use. One cast and you’ll be hooked. Fish with it and you’ll have great stories to tell. A love story, too. Get the free iPhone app. Or free Android app

Frequently Asked Questions

What is the cost of iBobber and the App?
The app is free. The Suggested Retail Price of the iBobber is only $99.99 (U.S.). Download the free app for your iphone/tablet from iTunes or free app for Android from Google Play. iBobber comes complete with a USB charger, carrying pouch, and product information guide. Please note that 2nd Day Delivery from must be ordered by 1pm EST
How does iBobber work?
Simple. Just attach a fishing line through the eyelet of the iBobber and cast where you want to see under the water, or where you want to begin to map the contour of the waterbed. The iBobber turns on upon contact with the water, and "sees" fish, water temperature, and depth (2 fish sizes - orange depth tag is 15" and under, green depth tag is over 15"). To map the contour of the waterbed contour down to 135ft, all you do is tap the app to the Waterbed Mapping screen, tap to begin, reel in the iBobber at a slow rate, tap to stop, and you've got a contour of the waterbed. Couldn't be easier. And even better, the iBobber can be used from shore, boat, or dock.
Will iBobber® work with every Apple and Android phone and tablet?
Currently iBobber works with smartphones and tablets using Bluetooth® Smart 4.0 that support iOS (Apple) 6.0, 7.0, and 8.1 operating systems, and phones and tablets for Android that run v4.3 and later. This includes iPhone 4S, iPhone 5 and 6 series, iPad 3 & 4,and  Mini, and phones and tablets for Android that run v4.3 and later. We will not be supporting the Windows phone or Blackberry. Download the free app for your phone/tablet from iTunes or free app for Android from Google Play. 
What is Bluetooth® Smart, and why do we use it?
Bluetooth Smart 4.0 is the next generation Bluetooth. And we're the only fishfinder to use Bluetooth Smart® 4.0. Bluetooth Smart is very clever technology that does a really good job keeping devices continually paired. And in our case, up to 100' away. Unlike wi-fi, Bluetooth Smart provides a more secure connection without sucking the life out of your smart device battery (talk on your cell for an hour over wi-fi, two if you're lucky, then check your battery). A wi-fi link is designed to always be up, and hopefully, connected (and as connected draining your smart device battery). If the wi-fi link goes down it needs to be re-established and it's up to the smart device to do that... searching to make a connection... draining your device battery - and - between connections - data is lost. Bluetooth Smart is designed for locations where signals drop or fade. Bluetooth Smart enables and maintains a strong, low energy connection with a smart device, and when needed, the unit powers up, negotiates a data link (highway), sends its data, then shuts down the data link. This strong, low energy connection, and on/off data highway when needed, is what makes Bluetooth Smart the ideal solution for products that will benefit from long battery life, such as the iBobber (up to 10 hrs on each charge). 
Will the iBobber app get updates?
Yes. As we add even more functionality, we'll make updates available. As a matter-of-fact, we're already into our 3rd release. In addition, we are developing other products to help make your fishing the best it can be. Check back soon to see them.
Is the iBobber waterproof?
Yes.  The iBobber case is sealed so water won't get in. And it has an IP67 protection rating. Wondering what IP67 stands for? Here's the skinny:

In simple terms, you don't want ingress of dust or water into the iBobber case. You want protection for the iBobber, and ultimately, protection for your fun day of fishing.

IP = ingress protection.
6 is the best rating against solid particles, which means that iBobber is dust tight, protecting against dust like a superhero. Mistakingly dredge iBobber in that bowl of flour meant for your fish-fry, and the flour won't get in.

7 is the second best rating against water, which means iBobber is suitable for submersion. That's pretty darn waterproof. So you'll have no worries as iBobber floats along finding fish for you, maybe helping make that day of fishing the best day ever.
Can I use iBobber for ice fishing?
Yes. Nice thing about using iBobber, if you need to leave your ice shanty for any reason, you can take your smart device with you and keep tabs on the fish, and/or see if you've got a strike.
Who should use the iBobber?
Anyone who likes to find and catch fish, and wants to find and catch more of them.
What is the cost of the iBobber?
Suggested Retail Price is only $99.99 (U.S.). Please note that 2nd Day Delivery from must be ordered by 1pm EST.

Of course. iBobber has a 1-year Limited Warranty that covers your purchase/return for up
to one year if the iBobber is defective. You are responsible for shipping the iBobber
back to us with our Return Authorization, and once we make sure it hasn't been externally
damaged, which led to the defect, we would send you a new one. 
As for our return policy... if
purchased directly from we operate like many retailers— you can return the
iBobber with our Return Authorization within 30 days of purchase. The iBobber and all its
accessories will need to be unused and in the original box. You would be responsible for

The concept for iBobber began in the Spring of 2012 with a very simple question that Alex, our CEO, asked of himself when he was trying to catch bass with his father-in-law. Fishing from the back of the boat, Alex looked longingly at Jim's boat-mounted fish finder that was mounted too far forward to see the screen clearly. And Alex wondered, "why can't I have a fishfinder connected to my iPhone (or Android), then I can see it anywhere I'm on the boat? Or from shore, or a pier, or a kayak, or from a friend's boat?!" And so iBobber was born.

As you get to know us, you'll find that ReelSonar is a company not only created by guys who love to fish, but that we're dedicated to helping all anglers, amateur to professional, young to old, bait lovers and lure aficionados, find more fish so they can catch more fish.

Bottom line— we love fishing and want to do everything we can to make fishing the most fun it can be for everyone. Get your own iBobber at one of our Retailers, and get the free iPhone app or free app for Android.

FAQ: “How do I delete extra Trip Logs?”

October 08, 2015

When it comes to technology, I have a tiny attention span with user manuals, and I’m sure many of you feel the same way. I try to “wing it” and push enough buttons to figure out how something works and then save the user manual for when I get stuck. This principle also applies when I test a new piece of fishing gear. If the gadget or piece of apparel is user-friendly enough that I don’t have to refer to the user manual all the time, that’s definitely a major selling point. I love the iBobber for its simplicity and user-friendliness. Anglers of any experience level can quickly pick up on how to use the iBobber and its smartphone app,...

Five Unconventional Ways to Use the iBobber Waterbed Mapping Feature

September 30, 2015

Most people purchase iBobbers for fishing, affordability, user-friendliness, the convenience of its small castable size, and Bluetooth Smart Technology. But when you buy something, you want to get your money’s worth, so we encourage people to be creative with how they use their iBobbers. Let’s look at the Waterbed Mapping feature on the iBobber app as an example. By casting and reeling in your iBobber, you can use your smartphone to see the water depths, structures, and vegetation along a lake or riverbed, which can help you decide where to fish, place fish traps, and what lures to use. But this ability to visualize a waterbed can have plenty of other practical applications for water-based sports, boating, scuba diving, and...
