Deeper PRO+ 2 Sonar Fish Finder - Portable Fish Finder and Depth Finder For Kayaks, Boats and Ice Fishing with GPS Enabled | Castable Deeper Fish Finder with FREE User Friendly App

Wife grabbed this for an early birthday gift and it’s been a blast for fish at the pier. It’s easy to use after the initial setup, just toss it in the water, connect via wifi, and you’re off. It can spot fish with ease. I'm not expert on underwater structure but it seems to pick up those too. The GPS mapping is awesome, I can make maps from and save my favorite spots. It stays connected up to a couple hundred feet away. The app is really easy to use and has lots of options. Battery seems to last a long time but I don't just leave it in the water and it charges quickly it’s small about the size of a tennis ball. Overall, it’s made fishing more fun and less guesswork caught some good bluegill after my wife spotted some 5 feet deep. Highly recommend for anyone who wants a simple, reliable way to see what’s happening under the surface! Minor draw backs. I chose black and sometimes lose sight of it in the water but its accurate on the app and there are other colors to choose. The app does try to upsell you but it only seems to be each time you start the app. You pretty much need a dedicated pole for the sonar with heavy test. I think they recommended 20lb but I used 50lb braid. Had a lot of fun using it so far. Its a bit price but it does work well and overall love the design. Also because of the price I tend to stress out with it on the water.

This is very cool, still trying to figure it out all the way. But the concept is that it lets you know when a fish gets near the sensor. I set it up by using a fishing pole with no hook. Basically bring an extra fishing pole you’re not using. Charge up the sensor and use the provided attachment that comes with the sensor. Allow the sensor to sit in the water near your phone. When the sensor comes into contact with the water it turns on. Then you can cast it out. The app allows you to see what areas have the most activity. Then you can fish in that direction. Really does help with not wasting so mush time. I was fishing for about an hour and had not luck. You know the old fashion way. Not to be that guy, BUT after a few minutes I was able to get a bite or two. On the app, it shows how deep the water is at and how long the fish are in the area. The apps displays like line graphs. Kinda like a heart monitor at a hospital. After using the sensor I noticed I was fishing in a low activity area. I started to cast back in the area the sensor was detecting movement. I was able to catch a 9” bass this way (I know not impressive). After using the sensor for like 20 ish minutes. You could probably chop it up to luck. But it’s just another set of eyes. I fish in a lake where I can not see the fish. So it helps. The apps display line and the sensor was easy to use. Quality of the sensor felt great. Value for money, depends on how much time you like to waste. I like to fish and have a good time and I gage that on how many fish I catch. Hopefully this helps.

Absolutely love this fish finder! Easy to use. Very great detail. Make sure to use some good braided string, 20lb or better. The app is easy to use. Do have to pay a subscription for pro features. I don't care, it's cheap and worth it. You'll find fish in spots you wouldn't think. Accurate for depth. Battery life has been great. Used several times and not close to half yet. Reading the app and sonar data is awesome and fun! Connects no problem to phone. Read the instructions.

I picked this up to assist with fish locating from banks and on my kayak. Here's what I've learned... HELPFUL MATH: The device uses a cone scan, so there's a circular area of possibility on where the fish can be relative to device. This is obvious, but telling how BIG/WIDE that cone is varies based on water depth. Again, this is obvious. Digging into the Deeper site, you'll see that the following equation will help you figure the area out: 2depthTan(cone angle/2) 😬 😂 Here's what you need to know: To determine the cone width: For the 7* scan, multiply the water depth by 0.122 For the 20* scan, multiply the depth by 0.353 For the 47* scan, multiply the depth by 0.87 I typically use the 20* scan as I feel it's the best balance, so I've memorized that number. Just keep them in the notes of your phone and use them as needed. DON'T SEND IT INTO ORBIT: You'll need a stout rig if casting this from the bank. You don't need to bust the wallet to do this, but know that, unless you already have heavy-weight gear, there are additional costs to "get this working". I picked up a Berkley catfish spinning rod locally for under 30 bucks and added a 4000 series reel for another 30 or so. I spooled it with 50 lb braid and THOUGHT that would be sufficient. That was until the bail clapped at the peak of a cast which snapped the line and hurled the Deeper about 100 yards into the middle of the lake. I ended up stripping down to my boxers and swimming out in 50* water to retrieve my sonar. When my breath and pulse neutralized and I regained the feeling in my appendages two hours later, I re-spooled with 80 lb Power Pro braid and a 50 lb mono leader via an FG knot with a BACKUP link (see pics). Basically, I added a large surgeon's loop in the braid above the leader with a heavy-duty snap clip/swivel. Then, the short mono leader culminates with a swivel clip. I'm using a leader for a little extra "spring" just in case. I installed BOTH mounting bolts on the Deeper; one at the bank-fishing port (below the water line) and one for the boat connection (just above the water line). I then put the leader clip on the bank ring and the "backup" clip on the boat ring (there's a little slack here). That way, IF the mono/knot snaps, the backup clip SHOULD retain a grip on the Deeper. I'd rather do a polar plunge on my own terms. All that being said, with good braid and a decent rod, you can heave the crap out of this thing, giving you a worthwhile scan to shore. If you aren't willing to get the necessary gear, you can tie some light line to it and toss it like a baseball, but unless you're an MLB outfielder, your range will likely make using this impractical and not worth the investment. OVERALL PROS: • Versatile; you can use it in virtually any fishing scenario (with the appropriate gear/accessories) • Pretty easy to use once you figure out which mode is best for each intended use • For the MOST part, scanning is accurate, but it can get confused by sudden current (see below) • Fish icons are helpful for newer sonar users • Battery life is very good. I'm getting 5-7 hours of CONSTANT use out of it. • Very handy for kayak fishing, esp. with a good mount (I use YakAttack might mounts/arms as the reviews on the expensive boat attachment aren't stellar) • In a nutshell, it gives you sub-surface information that you wouldn't have otherwise which keeps you from casting blindly CONS: • HEAVY, at just over 3 oz., you MUST have a stout rod if you plan on casting it • Longer rods needed for casting make it impractical for bank fishing with cover (it's also extra gear to carry making this tennis ball-sized device significantly less portable • As you would imagine, using this in creeks or shallow rivers is impractical as the rocks/wood can destroy this thing on impact, and the churning current can give false-positives like early COVID testing • Phone holder for the rod is extra, and it's probably best to remove the phone between casts just to be safe • Offers a "night" mode which apparently produces a strobe effect so you can see it (cool), HOWEVER it this requires an additional, translucent top, but I can't find that option on Amazon or the manufacturer's site rendering it useless. (?!) • Can be glitchy uploading scans to the cloud; it can sometimes take SEVERAL attempts with large scans • Scans will "upload", but won't always show up in the cloud/be downloadable to other devices at times • Occasionally loses connection even just 3 feet away from the iPhone • Easily fooled by kayak paddle churn. If you are sitting still, or are very gently cruising, and you begin to paddle, it will give false fish readings if it's mounted on the side of the kayak • The 2D image of a 3D scan makes orienting fish direction a bit of a challenge. This is an issue with all devices like this. There's no way to tell if the fish are moving or stationary as the scanner is ALWAYS feeding information right to left on the screen - even if the device is still. Just something to keep in mind. CONCLUSION: If you are using this on a boat or kayak, you'll likely really love it, even with the occasional connection/upload glitches. If you're on the bank/shore with plenty of clearance and the right casting gear, it should work a treat as well. If not, it's still worth it, and likely better than many other options in its price range, but it's not exactly plug-and-play out of the box without stout gear at the ready.

3 years after purchase honest review: I purchased this unit in February 2022. The unit worked amazing and I loved the App and I felt that the sonar worked great both for ice fishing, casting from the shore, and attached to a kayak. I felt the best advantage of the system was access to the community topography scans that come with the pro account which I was paying for. However, this is where things took a turn. In July 2022 the unit stopped charging or putting off a wifi signal. It does come with a 1 year warranty so I sent it back and their customer service was great in that. Their customer service people concluded it was a manufacturer defect (something on the hardware board became disconnected), They sent me a brand-new unit. The whole process took a couple of weeks If this was the end of it I would be leaving 5 stars based on this experience. However Fast forward to January 2025, Took the unit out ice fishing it worked fine, went home to charge it and the same issue had arisen. It no longer would charge, and no longer would emit a wifi signal. I contacted support and let them know the issues I was having. They said that since the 1 year warranty had expired I would have to pay $90 for them to diagnose the product and do any repairs. ( I assume this is a battery issue based on numerous other 1 star reviews that list the same problem arising after the warranty period has expired.) IF you want an awesome sonar that works for 1 year but will eventually break and then you have to pay 50% of the cost to get it fixed then this is the one for you. But to me this seems pretty crummy on their end to not back their product with a longer warranty. Clearly, they figured out that the battery will only last a certain amount of time then customers will have to come back and pay to get it fixed. This just seems like bad business and disrespect to their customers. In all fairness, this unit was extensively used for the 2.5 years I had it. I did go ice fishing quite a bit with it so maybe it cannot actually withstand the very cold water temperatures when using it ice fishing. That being said the sonar is marketed for ice fishing which to me should mean that the system should be able to handle the cold temps as cold is usually a battery killer. If the battery is this prone to breaking one would think they would offer batteries for sale that the customer could swap out after a certain period time instead of having to pay $90. Which by the way their support is based in Europe so having to ship it overseas is a pain.

The Deeper Pro Sonar is an excellent tool for anglers. Setup is quick, and the connection to my phone is seamless. It delivers accurate depth readings and fish locations, even in challenging conditions. Compact, portable, and easy to use—well worth the investment for serious fishing trips.

Great product love this fish finder great option for shore fisherman! Gives a lot of valuable information that is very valuable, however highly recommended!

The fish finder work great, but did come a little out of balance. This caused it to be difficult to use the ice fishing feature. That was able to be fixed thoug by taping a lead weight inside the top to properly balance.
