## What is Fish Deeper?

Whether you’re a seasoned angler or just getting started, Fish Deeper helps you fish smarter, connect with others, and make the most of your time on the water. The app provides valuable insights into the waters you fish, helping you locate the best fishing spots, understand underwater terrain, and connect with the local fishing community. Perfect on its own or paired with Deeper sonar, it’s the ultimate tool for smarter fishing.

MAPS+ FISHING MAPS
Gain insights into bottom structure and fish-holding areas:
• 2D and 3D Depth Maps: Dive into the lakebed with 2D maps that reveal underwater islands, pits, drop-offs, and other features that attract fish. Use a 3D view for a clear, additional perspective to pinpoint key fishing locations.
• 2D and 3D Bottom Hardness Maps: Understand the lake’s bottom composition and distinguish between firm sand, soft silt, and other surfaces. This helps you identify areas where fish are more likely to be.

ESSENTIAL ANGLING FEATURES
Your go-to guide before, during, and after every fishing trip:
• Waterbody Hub: A dedicated space for each body of water where anglers can interact, share their catches, exchange tips, and discuss the latest trends. Each water includes a weather forecast tailored to that location, so you can stay informed on the best fishing conditions.
• Trending Lakes: Stay updated on popular nearby lakes, fishing activity, and real-time insights from the community.
• Spots: Easily find boat ramps and onshore fishing spots already marked on the map or mark your private points of interest.
• Catch Logging: Log your catches, including bait, techniques, and photos, and share your success with fellow anglers. Exact spots and details are kept private.
• Weather Forecasts: Check detailed weather forecasts tailored to your fishing needs to plan your trips accordingly.
• Offline Maps: Download maps for offline use and access location data easily anytime, anywhere.

JOIN THE ANGLERS’ COMMUNITY
Follow the news of your favorite lakes and get notifications about recent catches or activity nearby. See what others are catching, share your own achievements, and discover new fishing spots in your area. Whether you’re fishing from the shore, boat, or on ice, you’ll always be in the know.

ENHANCE WITH DEEPER SONAR
When paired with Deeper sonar, Fish Deeper becomes even more powerful:
• Real-Time Sonar Data: View sonar data in real-time to explore the depths and see fish activity firsthand.
• Bathymetric Mapping: Create depth maps from shore, boat, kayak, or SUP in both 2D and 3D.
• Ice Fishing Mode: Use your sonar as an ice fishing flasher and easily mark ice holes.
• Sonar History: Review and analyze your sonar scan history to better understand the underwater environment.
• Customizable Settings: Adjust sonar settings to fit your fishing style and needs.

The app also includes Maps+ with Sonar Protection, designed specifically for sonar users. This subscription provides coverage in case of accidental irreparable damage, loss, or theft, along with a 20% discount on sonar accessories and access to advanced depth and terrain maps in 2D and 3D.

### 5/5 — Simply the best

*2026-07-25, version 2.5.0*

Wow what a great boat, easily the best bit of fishing kit I’ve ever owned

### 1/5 — Save your money

*2026-07-21, version 2.5.0*

I bought the deeper max, downloaded the app, fully charged the sonar unit, put the unit in my pool to connect to it but the app won’t connect to the unit with me standing directly over the sonar unit.  The app is primarily concerned with you purchasing their maps

### 5/5 — Fabulous Quest

*2026-07-14, version 2.5.0*

Superb baitboat with fantastic customer support from Deeper. Yes there are issues for some most are user issues. The best boat for the money hands down

### 2/5 — Massive Softwareprobleme

*2026-06-29*

Die Softwareversion4.5.2 scheint massive Probleme zu haben. Wer kann, sollte besser auf ein Update verzichten. In der aktuellen Version wird die WLAN Verbindung zum Deeper nur sehr unzuverlässig erkannt. Es kommt immer eine Fehlermeldung „ nicht verbunden … ihr Deeper Sonar ist bereits mit der Deeper Sonar App verbunden“ und eine Schaltfläche „Fisch Deeper Nutzen“ welche jedoch keine sichtbare Funktion hat. Sollte doch mal kurzzeitig eine Verbindung aufgebaut werden, so wird nur die Position in der Karte, Batteriekapazität des Deepers und die Geschwindigkeit angezeigt, aber der Scanbereich bleibt schwarz. Obwohl es ein „innerhalb 24h erfolgt eine Reaktion“ Versprechen des Supports gibt, bleiben Mails seit mehreren Tagen unbeantwortet. Mit der App Version 4.5.0 tritt das Problem offensichtlich noch nicht auf.

**Developer response:** Hallo, vielen Dank für Ihre Bewertung. Es tut uns sehr leid, dass Sie diese Unannehmlichkeiten haben.
Möglicherweise verwenden Sie eine andere Anwendung, die die Verbindung der FishDeeper-App zu Ihrem Deeper stört.

Unsere Erfahrung zeigt, dass die Navionics-App dieselben WLAN-Protokolle wie die FishDeeper-App nutzt, was zu Störungen führen kann.

Deaktivieren Sie außerdem alle VPN-Dienste, während Sie den Deeper verwenden (falls Sie einen VPN-Dienst nutzen).

Sollte dies nicht helfen, möchten wir die Probleme untersuchen und eine Lösung finden. Bitte kontaktieren Sie uns per E-Mail unter support@deeper.eu. Wir werden den Fall detailliert prüfen und eine Lösung finden.

### 1/5 — Не подключается

*2026-06-08*

Deeper pro после обновления не подключается.

**Developer response:** Здравствуйте, жаль это слышать. Вот что попробуйте: 1. Подключите эхолот к зарядке. 2. Зайдите в настройки WiFi вашего телефона, там подключитесь к WiFi сети вашего эхолота. Если попросит пароль - он 12345678 3. Теперь включите приложение FishDeeper и дайте ему любые соглашения, которые попросит. Затем оно должно подключиться.

### 1/5 — Payer l’abonnement pour rien

*2026-05-27*

J’ai payer l’abonnement carte plus à 30€ par en et l’application me dit que je doit re payer

**Developer response:** Bonjour, nous sommes désolés d'apprendre cela. Ce n'est pas normal et nous souhaitons enquêter et trouver une solution. Veuillez nous contacter par courriel à l'adresse support@deeper.eu et nous vous aiderons.

### 5/5 — Deeper Chirp+2 und Deeper Quest

*2026-05-23*

Ich bin Besitzer eines Chirp+ 2 und eines Deeper Quest futterbootes und bin sehr zufrieden mit der Conectivität.
Die App funktioniert ausgesprochen gut und Fehler werden schnell gepatcht. Deeper macht einen guten Job. Daumen hoch. 👍🏼

### 2/5 — 使ってわかったこと

*2026-04-17*

深さ80mくらいまでしか反応しない！

**Developer response:** こんにちは。レビューありがとうございます。最大探査深度100mは、以下の条件が満たされた場合にのみ達成可能です。
- ソナーが水中で非常に安定していること（例えば、マウントを使ってボートに取り付けるなど）。これは非常に重要です。

- 波が少なく、ソナービームが海底に直接向けられていること。

- 海底の硬度や塩分濃度などの他の要因も、最大探査深度に悪影響を与える可能性があります。

- 7度、20度、47度のビーム角度を切り替えて、ご自身の環境に最適な角度をご確認ください。

ご不明な点がございましたら、support@deeper.euまでメールでお問い合わせください。

### 1/5 — App doesn’t work

*2026-04-14*

I purchased a monthly subscription through the app which generated an error. The fee has been taken from my account but whenever I try to look at maps it asks me to subscribe again. If I try it tells me I already am subscribed. Tried to get help through chat support only to be told it need to go to second level which will take 4 working days. 
Not good enough.

**Developer response:** We are very sorry for this situation. Most likely what happened is that Apple has activated the subscription on your Apple ID account, but you were logged in the FishDeeper app with some other account. Our support team will help you (sorry that our response time is so long right now, we are actively working on improving it).

### 3/5 — Needs some fixes but has promise

*2026-03-07*

Only my first day. it definitely gathered some good data.  But  it has some flaws. 
1.  Stop asking me to subscribe after I already paid for it
2. Allow me to stop scanning once I’ve reeled it back in. Let me cast and start it back up. 
3. Sometimes the depth bar at the top just disappears and I can’t figure out how to get it back. I had to close the app and reopen.

**Developer response:** Thanks a lot for your review! Sorry for the issues you had. 1. The app shouldn't offer you to subscribe if you're already a subscriber - that's very odd. We'll look into this. 2. The sonar will stop scanning once it's out of the water. It could be that the 2 metal pins on the bottom of the sonar were still wet, and sonar thought it was in the water and was scanning briefly. 3. If you tap on the top part of the screen - the depth gauge will hide, making the screen bigger. Just tap the same spot, and it will reappear. If you have any outstanding issues or questions - please email us at support@deeper.eu and we will help you. Thanks.
