Blue Sea Systems 5006 ST Blade Fuse Block
Blue Sea Systems 5006 ST Blade Fuse Block is the market-leading multi-circuit distribution solution for fishing electronics power supply, offering modular blade architecture and heavy-duty, corrosion-resistant terminals that stand up to vibration and saltwater. For anglers it outshines single inline holders by centralizing protection for fishfinders, GPS and accessories—reducing wiring clutter and simplifying expansion and maintenance; it carries a premium but often lowers lifecycle costs through durability and easier system upgrades compared with the other inline-focused products on this list.

Ancor Marine Grade ATO/ATC Fuse Holder
Ancor Marine Grade ATO/ATC Fuse Holder is a budget-friendly, marine-rated inline holder that makes quick retrofits and accessory additions simple for fishing electronics. While it lacks the sealed protection of the Sea‑Dog unit and the heavy-duty construction of BEP or the centralized convenience of the Blue Sea block, Ancor's lower price and broad ATO/ATC compatibility provide an economical technical advantage for adding multiple low-current circuits without a big upfront investment.
