Each device offers unique features and advantages tailored to different fishing needs. This article will explore these two products in detail to help you decide which one is right for you.
Price Comparison
The Garmin GT20-TM is priced at $86.24, while the Reelsonar Portable Fish Finder costs $89.99, making the Garmin about 3% cheaper. If budget is a primary concern, the lower price of the Garmin might make it a more appealing option. However, it’s worth noting that the price difference is relatively minor, which suggests that other features and functionalities might play a more significant role in the decision-making process.
Performance and Functionality
In terms of performance, the Garmin GT20-TM boasts a downvu capability of 500 watts and operates at CHIRP frequencies of 435-475 kHz and 800-840 kHz. This powerful setup allows for detailed imaging of underwater structures and fish. In contrast, the Reelsonar Portable Fish Finder has a depth range of 135 feet and relies on Bluetooth connectivity to sync with your smartphone. While the Garmin targets a wider frequency range for enhanced detail, the Reelsonar offers a more portable solution for anglers looking to fish from various locations.
Ease of Use
The Reelsonar Portable Fish Finder is designed for ease of use, making it suitable for anglers of all skill levels. Its Bluetooth connectivity allows you to view data on your smartphone, making it user-friendly. Meanwhile, the Garmin GT20-TM requires a bit more installation effort as it is a transom mount transducer meant for boats. If you prioritize convenience and portability, the Reelsonar’s design may be more appealing, especially for casual outings or when fishing from shore.
Battery Life and Portability
The Reelsonar offers over 10 hours of battery life, which is a significant advantage for long fishing trips. It’s also small and lightweight, making it easy to carry around. In contrast, the Garmin GT20-TM is mounted on a boat and does not require a separate battery. However, it’s less portable and isn’t designed for quick relocation. For anglers who value mobility, the Reelsonar’s battery life and compact design make it an excellent choice.
Target Audience
The Garmin GT20-TM is ideal for serious anglers who fish regularly from boats and require in-depth sonar readings. Its advanced features are well-suited for those looking to catch a variety of fish species. On the other hand, the Reelsonar Portable Fish Finder caters to casual anglers, hikers, and campers who might want a quick and effective solution for finding fish without the need for extensive equipment. Depending on your fishing habits, one product may serve your needs better than the other.
Sales Rank and Popularity
The Garmin GT20-TM has a sales rank of 21,359, while the Reelsonar Portable Fish Finder is ranked at 10,591, indicating that the Reelsonar is a more popular choice among consumers.

Features Overview
The Garmin GT20-TM offers advanced sonar technology with multiple frequency settings for detailed imaging, making it suitable for serious fishing enthusiasts who need precise data. Conversely, the Reelsonar Portable Fish Finder provides a user-friendly app that displays depth-tagged fish icons and includes a fish alarm feature. For those looking for high-tech features and detailed sonar, the Garmin excels, while the Reelsonar is geared more towards simplicity and convenience.
Which should you buy?
Choosing between the Garmin 010-01960-00 GT20-TM Transom Mount Transducer and the Reelsonar Portable Fish Finder ultimately depends on your fishing style and needs. If you prioritize detailed sonar imaging and are prepared for a more permanent setup on your boat, the Garmin is the better choice despite being slightly cheaper. However, if you value portability, ease of use, and longer battery life for casual outings, the Reelsonar is likely the better option for you. Consider your fishing habits, the environments you fish in, and how much convenience matters when making your decision.
