To get here, tap the house icon at the bottom of the screen.

To access registration, units of measurement, and other settings, click the “Settings” icon on the bottom left corner. More on the Home Screen and features to follow.



This is the first screen of “Settings”, to register/change your info, select “Personal”. Choose your measurement. You also pair your iBobber through this screen (Bluetooth Smart sync), change settings like reel-in speed for waterbed mapping and demo mode (when you can’t wait to show your friends how cool it is), and turn on our Anti-Glare mode.



Sync your iBobber with your device through the “Bluetooth Smart sync” option on your “Settings” screen. The iBobber turns on either when it’s in the water or unplugged from the USB charger, so you’ll want to be prepared to fish when you sync it. Here’s what you’ll need to do when you’re ready to use the iBobber:

  1. Attach the iBobber to your fishing line by attaching your line through the higher of the two attachment points. We suggest you use a swivel and make sure it’s locked so the iBobber doesn’t become separated from the line. It gets scared when it is separated from you. Don’t scare iBobber
  2. Place the iBobber into the water nearby. The water will activate it, turning it on. Don’t judge, we all have our “things”. You’re now ready to sync!



  1. Tap “Bluetooth Sync” (image 10).
  2. The iBobber will appear on your device, listed by its nickname. Tap the circle next to your iBobber nickname (image 11). When the connection is made, the Sonar icon in the top navigation between the fish and waterbed silhouettes will turn orange (image 12). You’re now ready to find fish up to 100’ away. Note: The Bluetooth ball continues to spin.



Note 1: The first time you use the iBobber you’ll pair the iBobber (nickname) with your phone. If you and a bunch of friends are syncing for the first time, you’ll need to do it separately — cast yours into the water, sync, then your pal casts theirs, syncs, then another friend can cast, etc.

After your first sync, your iBobber/app remembers your nickname so using the iBobbers together is not an issue.

Note 2: While your phone will remember your iBobber, and your friend’s phone will remember his iBobber, if you’re out and forget your phone, or vice versa, you can connect with your friend’s iBobber, or theirs with yours. However, when connected to theirs, you won’t be able to connect with your own at the same time, etc. One iBobber to one device at a time. What can we say? We’re old-fashioned that way.

Note 3: When fully charged, the iBobber turns on when first disconnected from the charger and remains on for 25 minutes. This is for when you need to update the firmware.


Tap the Sonar icon to get to the Sonar screen. Fish are tagged with their depth and size. The orange tag is a fish under 15”. The light green tag is a fish over 15”. A depth gauge is on the left. The bottom of the screen reflects the waterbed contour. (Enter) To use the Raw Sonar Mode (image 14), just tap the fish icon at the top of the app screen; do the same
to get it back to standard Fish Sonar Mode (image 15).


Note: Sonar mode is indicated by the dark green fish in the top left navigation, with an arrow indicating it.



Tap either the weather icon on the Home Screen, or from Waterbed Mapping tap the Sonar icon (green fish / top navigation) tap Home (little house), then tap the Weather icon. You’ll see the Weather — Current Temperature, Daily High/Low, Precipitation %, Wind Speed/Direction, and Barometric Pressure.



Tap either the Calendar Icon on the Home Screen, or from Waterbed Mapping tap Sonar (green fish). Then tap the Home icon, then tap the Weather icon You’ll see the Calendar and Moon phases by month. Tap today’s date to see the Moon Rise, Moon Set, and Sun Rise and Sunset. (Tap the past date to see past Trip Logs)



Tap either the Trip Log icon on the Home Screen or from Waterbed Mapping tap Sonar (green fish). Then tap the Home icon, then tap the Trip Log icon. You’ll see the Trip Log. If you’ve tapped a GPS Tag on any screen, the Date, Time, and Location will be auto-filled. If not, to Log a location/trip, tap the GPS pin icon on the bottom right of the screen. Now, touch the Title field and a keyboard will open. Enter the title of your adventure and the rest of the fields, tapping one at a time to enter the info you wish to save. Tap Done when finished.



To share via text, email, Twitter, or Facebook, just tap the Share Arrow next to the trip log icon to share. Tap the photo icon to capture pictures.

FAQs about Reelsonar iBobber Portable Wireless Bluetooth Fish Finder

What is the iBobber’s bare minimum depth?

Like all sonar technologies, the iBobber requires a certain minimum depth to operate. We have a 4-foot minimum depth.

How much time does iBobber take to charge?

Our battery currently offers the best battery life for portable fish finders, lasting between 7 to 10 days on a single charge. Be careful to charge your smartphone and iBobber for at least 30 minutes before to going fishing.

Can you use the iBobber in salt water?

The iBobber is the greatest personal fish detector available on the market for fishing from shore and docks. It’s also great for bottom-sounding regions that are inaccessible to boats while kayaking or canoeing. It is excellent in finding fish and other structures in ponds, lakes, streams, and rivers. It also works in both freshwater and saltwater.

Does every fish finder display depth?

The electronic instrument that sailors buy as a fish finder is being used more and more as a depth finder. This is so because the majority of fish finders have a depth function as part of their basic functioning. However, you may still buy electrical gadgets (depth finders) that are used to measure depth.

How long does it take a fish finder battery to charge?

Therefore, if you have our charger, which charges at 1.5 amps, and our 5 amp-hour battery, our charger will fully recharge the battery in 3.33 hours. If you have our 800ma charger, it will take 6.25 hours to fully recharge a 5ah battery from empty.

Why is my Ibobber’s blue light blinking?

When the bobber is charging, a blue ring around it illuminates and then blinks. As instructed, do not keep the bobber in the charger after charging because doing so will drain the battery.

Is iBobber GPS-enabled?

There is a built-in GPS in the iBobber.

Are fish finders powered by batteries?

Electricity is required for the operation of electronics like fish finders. Batteries installed in the battery compartment provide electricity to boats. The majority of fish finders use a DC 12–24 volt power supply, with the exception of special, very tiny models.

Is an iBobber capable of trolling?

The iBobber can be used as a fish alarm, cast to map the waterbed, or trolled next to your kayak. By indicating the water depths where the fish are lurking, it takes the guesswork out of selecting the right lures, allowing you to spend more time reeling them in.

How much area can a fish detector search?

REASONING ABOUT YOUR RETURNS. To the left and right of you, up to 400 feet, Humminbird Side Imaging sonar employs a micron-thin beam to create a “sonar snapshot” of the surrounding region.
