Deeper Smart Sonar PRO Plus 2

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.

This is an outstanding product, as a fish finder and a mapping tool. It provides depths, water temperature, bottom structures, and fish all to an app on your phone. Great for mapping piers and lakes. "Con" The only con I have is that I could not get a signal far out to sea. This can be overcome I just have not figured it out yet. Great overall buy. Must have for me.

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 0.122For the 20* scan, multiply the depth by 0.353For the 47* scan, multiply the depth by 0.87I 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.OVERALLPROS:• 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 blindlyCONS:• 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.

Works great for hole hopping on ice

Works great for ice fishing. Works good on phone. But Works even better on a iPad. Has very good battery life. Easy to setup, and connection great range.Prefer this over a vexilar due to portability and gives you extra features such as water temps and GPS that a vexilar does not have.

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.
