Product Overview
The 780044-1 UC H7 R2 Helix 7 Unit Cover Silicone Screen Protect is a protective cover specifically designed for the Helix 7 series fish finders, while the YakAttack CellBlok with Switchblade Transducer Arm serves as an all-in-one mounting solution for fish finders on kayaks. The Helix 7 cover is priced at $34.60, making it significantly more affordable than the YakAttack system, which retails for $104.95. This price difference of about 67% positions the Helix 7 cover as a budget-friendly option for users looking for protective accessories.
Design and Compatibility
The Helix 7 cover boasts a durable black silicone design that perfectly fits the Helix 7 series models, ensuring that all buttons and grooves are accessible. This tailored fit is crucial for maintaining the functionality of the device while offering protection. On the other hand, the YakAttack CellBlok is designed to be a universal solution, compatible with various track systems and allowing for easy installation without drilling. This feature makes it an appealing choice for kayak users who want a versatile mounting system.
Functionality
The Helix 7 cover offers essential protection against scratches and bumps, extending the lifespan of the fish finder when not in use. Its easy installation—simply placing it over the screen—makes it user-friendly for all boat fishers. Meanwhile, the YakAttack CellBlok enhances the user experience by providing a streamlined setup for fish finders. It includes a track-mounted battery box and a patented SwitchBlade Transducer Arm, which allows for flexibility in positioning the transducer for optimal performance.
Installation Process
Installation processes differ significantly between the two products. The Helix 7 cover requires no tools and can be put on or taken off easily using two front handles, making it a hassle-free option for those who may not be tech-savvy. In contrast, the YakAttack CellBlok employs a no-drill installation method, which means users can attach or detach the entire system by loosening just two knobs. This feature not only simplifies the process but also eliminates the risk of damaging the kayak with unnecessary holes.
Weight and Portability
The Helix 7 cover is lightweight, emphasizing portability for users who need to quickly protect their devices. The YakAttack CellBlok, while also designed to be lightweight at just 1.4 lbs, focuses on providing ample space for a 10ah battery and larger cable wraps, which may be essential for modern fish finders. The difference in weight is marginal, but the emphasis on space in the YakAttack product highlights its functionality for more extensive setups.
Target Audience
The Helix 7 cover appeals primarily to users of the Helix 7 series fish finders seeking protection and longevity for their devices. Its simplicity and lower price make it ideal for casual fishers. Conversely, the YakAttack CellBlok targets kayak enthusiasts who are looking for a comprehensive solution that encompasses both mounting and battery storage. This dual functionality caters to a more specialized audience that values efficiency and ease of use on the water.
Bestseller Ranking
In terms of popularity, the Helix 7 cover has a sales rank of 10,393, indicating a solid standing in the market for fish finder accessories. The YakAttack CellBlok, with a sales rank of 27,242, shows that while it is a respected product, it does not enjoy the same level of popularity as the Helix 7 cover. This difference in sales rank may reflect the broader appeal of protective covers compared to specialized mounting systems.
Which should you buy?
Ultimately, the decision between the Helix 7 cover and the YakAttack CellBlok boils down to your specific needs. If you own a Helix 7 series fish finder and are looking for an affordable way to protect your investment, the Helix 7 cover at $34.60 is a compelling choice. However, if you require a multifunctional mounting solution for your kayak that allows for easy setup and versatility, the YakAttack CellBlok, despite its higher price of $104.95, may be the better option. Each product serves its purpose well, catering to different aspects of fishing technology.
