⚖️ Final Say
Read the summaries of what reviewers think about Deeper below.

“I wasn’t won over by Deeper’s first foray into the fish-finding market, but they’ve got me hooked now. Light, portable, easy to use, and ultra-capable: that’s what the Deeper line-up promises–and it’s clear they deliver! Whether you fish from a kayak, work the hard water from a hut, or cast from shore, Deeper’s products will improve your chances of the catch of a lifetime.”
“Once fully charged, the Deeper unit will last for around four hours of continual use before requiring a recharge. It does not require a phone or internet connection to operate, and uses no internet data. The deeper unit is not heavy to carry around. This unit is built to last.”
“The Deeper Pro+ will improve your angling, both in speed and accuracy. The price is fair considering the amount of technology involved in the fish finder, and you’d still pay more for a lot of other non-essential equipment. This is a powerful tool to have in rod bag.”
“The Deeper Smart Sonar PRO+ in many ways is creating a category. With rock-solid engineering and backed by well-crafted software, it’s almost a surprise that the PRO+ comes in a portable, castable package. Put together, it’s no wonder the most common concern buyers have is losing track of their transducers.”
“I really like my Deeper Pro + fish finder. The device was easy to learn and is very easy to use. You simply submerge it in water, wait for the transducer to sync to the app, and start reeling it in. The transducer has great sensitivity and is easy to adjust from 90 kHz to 290 kHz and back.”
“The Deeper Start Smart Fish Finder falls is a decent and often reliable piece of technology that is marred by few, occasional hiccups. And while they certainly don’t deter one from the device’s impressiveness, they definitely do make it worth a thought before the buy.”
“Both the PRO and PRO+ offer an extraordinary value for such a useful unit that makes the precision of sonar fish finding available to all anglers. The PRO is less expensive than the PRO+, making it the first choice for this reason. However, if you fish certain waters heavily, the ability to make your own detailed maps of your favorite hotspots can be a big plus; if so, choose the PRO+.”
“With it, you don’t even have to be on a boat to locate fish habitats. It is an excellent fish finder even for shoreline fishing and ice fishing. What’s more, it doesn’t matter if the rain is pouring, the sun is right above you, or the biting winter cold surrounds you. With the castable Deeper Smart Sonar PRO+ With GPS, you’ll be catching fish in far less time than without one. You don’t have to equip your small boat with bulky and expensive fish-finding devices when all you need is a tiny ball to point you in the right direction.”
“The Deeper Smart Sonar PRO is a deeper smart portable fish finder that has a WiFi connection with impeccable transmission power. It has the capability of gathering a lot of data due to its higher frequency and amazing resolution. The WiFi connection enhances its range of scanning and transmission. The connectivity is also top notch under all kinds of conditions with a range of up to 330 feet.”
“These devices are arguably the best deep smart fish finders to get especially for professional anglers. This is because it comes with some pretty amazing features and traits that make it stand out from the rest. Believe it or not, it is the only fish finder deeper that has the ability to scan down the water to find fish up to a depth of 330ft and can cast out up to 330 ft.”
“Deeper is a solid company that is selling this accurate fish finder that is a bit pricey and has some connectivity issues. This product is still a great tool for helping kayak anglers catch fish. I recommend that most readers purchase the newer Deeper models to obtain the latest features.”
“With this product, you can cast off from the shore, your boat, and even enjoy some ice fishing. Deeper now offer the chance to get some of the functions of expensive units at a fraction of the price. When you add in the mounting bracket, this device can become a great addition to any small boat or kayak. With the potential for use as a flasher during ice fishing, it’s clear this unit is quite versatile.”
“The CHIRP+ Smart Sonar is an all-round fishfinder and my number one choice, while the Smart Sonar PRO is perfect for creating detailed bathymetric maps. The Smart Fishfinder START can be the safest bet for beginners.”
“The Fishfinder will definitely put you in that spot where you can easily catch fish. The broad daylight condition is brilliant and enables you to find that weedy area where you can easily spot fish. If you want to catch a bunch of fish, then we highly recommend you give the Deeper Smart Sonar Pro+ a try.”
“Deeper Smart Sonar Pro+ is a worth-considering option for those anglers and weekend warriors who want a portable and reliable fish finder and depth detector for their small vessels. Its wide range makes it compatible with a variety of fishing types.”
