Dimension comparison
Design and build quality
Both the Deeper PRO+ 2 and the Deeper Start feature a sleek and lightweight design intended for portability. The PRO+ 2 is described as wireless and lightweight, making it a seamless addition to a tackle box for elite anglers. Similarly, the Start model emphasizes a lightweight and sleek design that facilitates a seamless reel without messy wires. Both units are physical castable devices that rely on mobile devices for display, eliminating the need for bulky standalone screens. The build quality focuses on durability for water environments, though specific IP ratings are not detailed in the provided data. The Start model specifically highlights the absence of fiddly external batteries, suggesting a more integrated internal power design compared to typical setups.
Sonar beam technology
The Deeper PRO+ 2 offers a versatile sonar array with wide, mid, and narrow beams. This configuration allows users to cover large expanses of water or drill down on specific spots depending on the fishing scenario. The availability of three distinct beam types provides flexibility for different water conditions and target species. In contrast, the provided data for the Deeper Start does not specify the number or type of beams available. While it functions as a portable sonar fish finder, the lack of specified beam options suggests a more standardized approach suitable for general use rather than specialized matchplay. The PRO+ 2 explicitly caters to users who want to take their matchplay to the next level through this beam versatility.
Performance and accuracy
Accuracy is a key differentiator between the two models. The PRO+ 2 displays unerring accuracy in the water with a specified target separation of 0.4 inches when using the narrow beam. For wide and mid beams, the target separation is 1 inch, allowing anglers to easily pinpoint target species and track even the tiniest lure when vertical jigging. The device maintains accuracy at depths up to 330 ft. The Start model boasts high-level specs that help users make the most of each trip, but specific depth ranges or target separation measurements are not provided in the available information. Consequently, the PRO+ 2 holds a measurable advantage in documented precision and depth capability.
GPS and mapping capabilities
Global Positioning System functionality varies significantly between the two units. The Deeper PRO+ 2 includes built-in GPS, which allows users to create bathymetric maps from the shore, dock, or bank simply and effectively. All maps are saved to the integrated Fish Deeper app, enabling detailed analysis of underwater structures. The Deeper Start automatically saves every scan with time and location for easy revisits, indicating some level of location tagging. However, the explicit capability to create bathymetric maps is attributed to the PRO+ 2. This makes the PRO+ 2 more suitable for anglers who need to chart bottom contours over time rather than just marking fish locations.
Connectivity and app integration
Both devices utilize own dependable Wi-Fi with rock solid connectivity. This ensures that the fish finders generate their own network, meaning the Start model won't eat up mobile data during operation. Both units pair with the Fish Deeper app on mobile devices. The app is free to download and compatible with iOS and Android devices for both models. Through the app, users can instantly see useful data like fish location and size, depth, bottom contour, and vegetation. The connectivity experience appears consistent across both products, relying on the same ecosystem for data visualization and storage.
Battery life and efficiency
Power efficiency is highlighted differently across the product lines. The Deeper Start emphasizes that no external batteries are required, implying an internal rechargeable system designed for convenience on family trips. This reduces the gear load for shore anglers. The PRO+ 2 is described as wireless, but specific battery life hours or charging methods are not detailed in the provided text. Both devices prioritize eliminating messy wires to ensure a seamless user experience. The Start model's specific mention of no external batteries suggests a focus on minimizing setup complexity for casual users, whereas the PRO+ 2 focuses on performance capabilities.
Price and value
The price difference is a major factor in the decision-making process. The Deeper PRO+ 2 is listed at $159.99, reflecting its advanced features such as GPS mapping and multiple beam options. The Deeper Start is priced at $89.99, positioning it as a more accessible option for beginners or family trips. The Start model offers a cost saving of approximately $70 compared to the PRO+ 2. While the PRO+ 2 offers more technical specifications, the Start provides core functionality like fish location and depth finding at a lower entry point. Value depends on whether the user requires bathymetric mapping and specific target separation data.
Which one should you buy?
Choosing between these models depends on your fishing goals and budget. The Deeper PRO+ 2 is the recommended choice for serious anglers who need detailed data, such as 0.4-inch target separation and bathymetric mapping capabilities. Its 330 ft depth range and multiple beam options support elite matchplay. The Deeper Start is ideal for shore anglers and family trips who want to get on with catching without complex setups. It allows users to fish in minutes and saves scan locations without requiring external batteries. If budget is the primary concern, the Start model provides essential sonar functionality at a lower price point.
