Veratron Blindplug f/Sumlog®

The Veratron Blindplug for Sumlog® is an essential marine instrument accessory designed for boaters who rely on speed and distance logging systems for accurate navigation and performance data. Whether you're running coastal routes, open-water fishing expeditions, or precision trolling patterns, this blindplug serves as a critical seal component that protects your Sumlog® transducer installation from contamination and corrosion. It's the kind of small but vital part that separates well-maintained marine electronics from systems prone to saltwater degradation and sensor drift.

This blindplug is engineered to fit Veratron's Sumlog® speed and distance measurement systems with precision-molded construction that ensures a watertight seal in the transducer housing. The compact design—measuring 6 x 3 x 7 inches and weighing just 0.3 lbs—makes it easy to stow and handle during maintenance or seasonal installation swaps. Its marine-grade materials are built to withstand UV exposure, thermal cycling, and the corrosive salt-laden environment that challenges deck hardware, ensuring long-term reliability without premature degradation or fit issues.

Boaters who maintain their own electronics—whether you fish commercially, run a charter operation, or simply take pride in vessel upkeep—will recognize the Veratron Blindplug for Sumlog® as a legitimate maintenance essential rather than an optional upgrade. Installation is straightforward for anyone with basic familiarity with transducer housings, and replacement during off-season storage prevents moisture intrusion that can corrode internal contacts and sensors. Keep spares on hand for extended trips; a failed seal can compromise your speed and distance data accuracy when you need it most, whether navigating to fishing grounds or verifying fuel efficiency across long passages.
