iBobber Castable Bluetooth Smart Fish Finder - Carp and Night FishingRailblaza 02-4179-11 Fish Finder Mount Low Profile

Design and Purpose

The iBobber Castable Bluetooth Smart Fish Finder is a standalone device designed specifically for fish detection, while the Railblaza 02-4179-11 Fish Finder Mount Low Profile is an accessory mount intended for use with compatible fish finders. The iBobber serves as a compact sonar fish finder that can be cast into the water and connects wirelessly to a smartphone or tablet, priced at £64.99. In contrast, the Railblaza mount, costing £15.26, is a mounting solution for Garmin ECHOMAP and STRIKER model fish finders, facilitating installation on kayaks, rails, tracks, and inflatables. This fundamental difference means the iBobber is a complete fish finding system, whereas the Railblaza is a supportive accessory designed to securely hold other fish finder units.

Compatibility and Device Integration

Compatibility is a critical factor where these two products differ sharply. The iBobber pairs with iOS devices running versions 6.0, 7.0, and 8.1, as well as Android devices from version 4.3 upwards, using Bluetooth Smart v4.0 technology. This enables it to connect directly to phones and tablets for real-time sonar data display. Conversely, the Railblaza mount is compatible only with Garmin ECHOMAP UHD, UHD2, and STRIKER fish finders (except for 4" Striker models), serving as a secure fitting rather than a standalone device. Therefore, the iBobber provides a self-contained ecosystem for fish finding, while the Railblaza requires an existing compatible fish finder to function.

Technology and Features

The iBobber offers sonar technology capable of scanning up to a depth of 135 feet, with fish depth tagging for two fish size categories: under and over 38 cm. It also provides waterbed contour mapping up to 30 metres away, enhancing underwater topography understanding. Additionally, it has a built-in strike alarm that alerts users when a fish bites, making it a proactive tool for anglers. The Railblaza mount, by comparison, does not feature any electronic or sonar technology itself; it primarily functions as an installation accessory. Its features are described broadly as “electronics, cold, communication and energy solutions,” which suggests its role is supportive rather than functional in fish detection.

Connectivity and Power

Connectivity is central to the iBobber's design with Bluetooth Smart v4.0 ensuring a strong, low energy wireless connection to smart devices. This low-energy connection optimises battery life while maintaining reliable data transmission from the sonar device to the user’s phone or tablet. The Railblaza mount does not handle connectivity or power as it is a passive mounting accessory without electronics or power requirements. Users of the Railblaza will depend on their mounted fish finder’s power and connectivity systems independently of the mount.

Installation and Usage

Installation and usability differ greatly between the two products. The iBobber is a castable device that can be thrown into the water and used immediately after syncing with a smart device, making it highly portable and easy to deploy in various fishing environments. In contrast, the Railblaza mount requires physical installation onto kayaks, rails, tracks, or inflatables using the RAILBLAZA StarPort system. While this makes the mount versatile in terms of mounting options, it demands a more permanent setup and is only useful in conjunction with compatible Garmin fish finders. Thus, the iBobber appeals to anglers seeking quick setup and mobility, while the Railblaza mount suits users wanting a secure, low-profile installation for their existing fish finder.

Price and Value

Price is a significant point of distinction, with the iBobber priced at £64.99 and the Railblaza mount at £15.26. The higher cost of the iBobber reflects its role as a complete fish finder with sonar technology, connectivity, and strike alarms, offering a comprehensive solution for fish detection. The Railblaza mount, costing less than a quarter of the iBobber, is purely an accessory designed to support other fish finders and thus offers value primarily in terms of mounting convenience and compatibility with specific Garmin devices. Buyers should consider whether they need a full fish finder or a mounting accessory when evaluating price against value.

Intended User and Application

The intended user base for these products differs due to their design and function. The iBobber targets anglers who want an easy-to-use, portable fish finder that works with their smartphones and tablets, including those interested in carp and night fishing. Its features like the strike alarm and waterbed contour mapping cater to recreational and serious anglers looking for technological assistance on the water. The Railblaza mount is aimed at users who already own compatible Garmin fish finders and want a secure, low-profile mounting option for their kayaks or inflatables. This makes the mount more of a specialist accessory for existing fish finder owners rather than a standalone product for general anglers.

Which should you buy?

Your choice between the iBobber Castable Bluetooth Smart Fish Finder and the Railblaza 02-4179-11 Fish Finder Mount Low Profile hinges on your specific needs. If you require a complete fish finding solution with wireless sonar up to 135 feet, fish size tagging, and strike alerts, the iBobber at £64.99 is the clear choice. It offers portability, compatibility with smartphones, and technology tailored for direct use in the water. However, if you already own a compatible Garmin ECHOMAP or STRIKER fish finder and need an affordable, versatile mounting system for kayaks or inflatables, the Railblaza mount at £15.26 is well suited for that purpose. Ultimately, the iBobber is a standalone device for anglers seeking smart fishing technology, while the Railblaza is an accessory designed to enhance the installation of existing fish finders.
