Overview of Products
In this comparison, we will explore the Deeper PRO+ 2 Sonar Fish Finder and the Retevis RM20 VHF Marine Radio. Each product serves a distinct purpose for marine enthusiasts, with the Deeper PRO+ 2 priced at £195.99 and the Retevis RM20 available for £162.99. The Deeper PRO+ 2 is geared towards anglers aiming to enhance their fishing experience, while the Retevis RM20 focuses on communication safety at sea.
Design and Build Quality
The Deeper PRO+ 2 Sonar Fish Finder boasts a sleek and lightweight design, making it easy to store in a tackle box and transport. Its portability is a significant advantage for those fishing from various locations, including boats and kayaks. On the other hand, the Retevis RM20 is designed for durability, featuring an IP67 waterproof rating, which allows it to withstand immersion in water up to 1 metre for 30 minutes. This rugged construction is essential for a marine radio, ensuring it remains functional despite harsh conditions.
Functionality and Features
The Deeper PRO+ 2 provides advanced functionality with its ability to locate fish and create bathymetric maps, offering pinpoint accuracy with a target separation of 1 cm when using the narrow beam. This feature is invaluable for anglers looking to track specific species and optimise their fishing strategy. Conversely, the Retevis RM20 excels in communication, equipped with built-in GPS for sending and receiving location information and distress signals. This ability enhances safety on the water, particularly in emergencies, making it crucial for any boating activity.
Technology and Connectivity
In terms of technology, the Deeper PRO+ 2 stands out with its smart technology that generates a reliable Wi-Fi connection, allowing users to receive real-time data up to 100 metres (330 feet) away. This connectivity ensures that anglers can access detailed information about their fishing environment seamlessly. The Retevis RM20 also incorporates advanced technology with its external GPS Class D DSC marine transceiver, capable of sending distress signals and recording calls. While both products are technologically advanced, they cater to different needs: one for fishing precision and the other for safety communication.
Usability and User Experience
The Deeper PRO+ 2 is designed for ease of use, allowing anglers to cast and reel in to create maps effortlessly. Its user-friendly interface is complemented by the integrated Fish Deeper app, enhancing the overall fishing experience. Meanwhile, the Retevis RM20 prioritises clear communication with a loud volume of 90-110 dB, ensuring that calls are audible even in noisy marine environments. The presence of external speakers further boosts its usability, making it easier for users to communicate over long distances.
Portability and Convenience
Portability is a strong suit for the Deeper PRO+ 2, which is specifically designed to be lightweight and easily transported. This feature is particularly beneficial for those who frequently change fishing locations or modes, such as from shore to kayak. The Retevis RM20, while portable, is primarily designed for fixed use on boats. Its robust build and waterproof capabilities ensure it remains a reliable communication tool but may lack the convenience of portability that the Deeper PRO+ 2 offers.
Price Comparison
When comparing prices, the Deeper PRO+ 2 is priced at £195.99, slightly higher than the Retevis RM20, which retails at £162.99. This price difference reflects the specialized features of each product. The Deeper PRO+ 2's advanced sonar technology and mapping capabilities justify its higher cost for avid anglers, while the Retevis RM20 provides essential communication features at a more accessible price point, appealing to a broader audience of boaters and maritime users.
Which should you buy?
Deciding between the Deeper PRO+ 2 Sonar Fish Finder and the Retevis RM20 VHF Marine Radio ultimately depends on your primary needs while on the water. If you are an angler seeking to improve your fishing techniques with advanced sonar technology and mapping capabilities, the Deeper PRO+ 2 is the superior choice, albeit at a higher price of £195.99. However, if your main concern is safety and communication while boating, the Retevis RM20 at £162.99 offers essential features such as built-in GPS and distress signal capabilities, making it a practical option for ensuring safety at sea.
