Read article →Build Your Own Fish Finder Battery: Gerd's 12.8 V, 15 Ah Power Box
By Gerd Werthenbach · Original article reproduced verbatim
Read article →Which fish finder battery will keep your unit running reliably?
A clear fish finder image is useless if the power runs out after just a few hours. Many anglers choose a battery based only on its Ah rating or price. This leads to unnecessarily heavy gear, short real-world runtime, or, in the worst case, an unsuitable charger. This article distills the existing comprehensive battery test and its real-world runtime findings into a clear decision guide.
Read article →Which fish finder helps you find the right fishing spots faster?
A modern fish finder can do a lot: It shows depth, bottom, vegetation, drop-offs, baitfish and, with live sonar, even movement in real time. That is exactly why choosing one is harder today than it used to be. A unit can look impressive on paper yet ultimately be a poor fit for your boat, power supply or the amount of time you actually spend on the water.
Read article →What Is a Chartplotter—and How Does It Help You Find Better Fishing Spots?
Anyone who uses a fish finder knows the problem: You pass over an interesting drop-off and see baitfish, a hard bottom transition, or a striking line. On your next visit, the area is almost impossible to find again without a reference point. A chartplotter does not save the catch—it preserves the observation. Over time, that creates a personal picture of your fishing water.
Read article →Is the Garmin Striker Vivid a Good Entry-Level Fish Finder?
The Garmin Striker Vivid series includes devices from 4 to 9 inches. It is designed for anglers who want a better view of the bottom, drop-offs, vegetation, and notable areas without immediately building a large chartplotter or network system. This can be a particularly well-matched approach on small boats, kayaks, and belly boats.
Read article →Which Fish Finder Is Really Right for You?
Anyone who has seen a fishing buddy lose track of the bottom in Norway's Hardangerfjord with a brand-new fish finder because the unit was not suitable for that application immediately understands the problem. A good fish finder can still be the wrong unit for a particular application.
Read article →What Can the Deeper CHIRP+ 2 Really Do on the Water?
The original article was written when the CHIRP+ 2 launched and asked the right question: What does the new device actually offer anglers? We retain the detailed technical assessment but clearly separate it from a current purchase recommendation. Check current product lines, prices, app versions, and package contents directly with the manufacturer.
Read article →What Does a Deeper Fish Finder Really Do for You on the Water?
Deeper sonars are among the devices that have changed shore fishing. You can cast them, use them on a kayak or belly boat, and map structure without having to drive a large boat over the spot. The previous guide rightly focused on exactly this point: For the first time, shore anglers can quickly get a picture of what is happening below the surface.
Read article →How Does the Deeper Pro Plus Perform After a Year on the Water?
A good long-term test should not pretend that the newest model is automatically better than everything that came before it. For the first time, the Pro Plus showed many shore anglers how much faster they could understand a body of water by saving depth, structure, and position together. That is exactly why this article remains important.
Read article →How Well Does a Deeper Smart Sonar Work in Real-World Use?
The original field test did not answer a laboratory question, but the more important one: Does a portable fish finder help when actually fishing? Our answer remains yes—if you use the device to explore and do not expect it to draw a ready-made fishing spot on the screen for you.
Read article →Which Beam Cone Should You Use with Deeper?
This was already one of the most common questions in the previous Deeper article: When should I use the narrow cone, when should I use the wide cone, and when should I use the medium cone with CHIRP? The principle has not changed. The setting is not the goal; the goal is answering your question on the water.
Read article →How Do You Interpret Deeper Images and Use Them to Find Real Hotspots?
The original article demonstrated this exact principle in a video: The sonar image is not the hotspot itself. It is a tool that helps you answer your question on the water more effectively. Are the fish holding along the shallow drop-off today? Is the forage moving along the weedline? Is there a calmer, deeper area in front of the groyne? Asking questions like these will help you find relevant fishing spots faster than simply waiting for fish arches.
Read article →How Do You Find Better Fishing Spots with Deeper Lakebook?
The existing Lakebook article highlighted an important idea: A large screen and a map are useful not only during the session. They also let you prepare and review. For shore anglers, that is often the greatest benefit of a castable fish finder. You no longer start from scratch on every visit.
Read article →Why Doesn’t the Absence of a Fish Arch on a Deeper Mean “No Fish”?
This existing URL is intentionally being retained. It answers a different, very specific question than our comprehensive guide to Deeper images and hotspots: What does it mean when you don’t see a distinct fish arch?
Read article →Deeper CHIRP or PRO+: Which Technology Really Helps You on the Water?
The old question “Is CHIRP worth it compared to PRO Plus?” was valid because it looks beyond the technical terminology. A fish finder is not good just because its frequency sounds modern. It is good if its display lets you see more quickly whether a drop-off is really there, how steeply it descends, and whether the area suits your target species and the season.
Read article →Which Castable Fish Finder Is Really Right for Your Waters in 2026?
The old “Top 5” comparison made sense at the time, but it included devices that no longer provide reliable buying guidance today. The strong URL is therefore being retained, but the content has been completely reassessed: current castable fish finders, clear limitations of the technology, and above all the question of what information about your waters you are really missing while fishing.
Read article →Garmin Striker Cast Review: Does This Castable Fish Finder Really Help Find Fish?
From shore, you often lack the information boat anglers take for granted: How does the bottom slope? Where do the weeds end? Is there a drop-off or hole in front of the spot? A lead weight tells you the depth. A castable fish finder lets you explore structure, bottom composition, and possible fish signals more systematically.
Read article →How to Read Sonar Images Correctly: How Do You Interpret Fish, Bottom, and Structures?
In the following article, we want to show you how to correctly interpret and analyze your sonar images. Many boat anglers choose a fish finder to locate fish and hotspots faster. But disillusionment sets in shortly after the expensive purchase, because very few fish finder images are easy to interpret at first glance. Beginners often have no idea what to make of the images and travel kilometer after kilometer before their rods even touch the water.
