Frequently Asked Questions
Q: Can I use a fish finder on a kayak without drilling holes?
A: Yes! Many budget fish finders, like the portable wireless model or units with transom mounts, attach without permanent installation. Some use adhesive mounts, clamp systems, or floatable transducers.

A: Most are water-resistant and designed for marine use, but check the IP rating. Avoid submerging the display unit, even if labeled “waterproof.”
