Fishing & Water

A transom-mount transducer attaches to the back of the boat above the waterline — easy to install without drilling into the hull, but readings can degrade at higher speeds due to turbulence. A through-hull transducer mounts through the hull itself for cleaner readings at speed, but installation is more involved and boat-specific.

Requirements vary by state and by waterway, but many states require a wearable PFD to be on board at minimum, with some requiring it worn at all times on certain waters or by certain age groups. Check your state's boating regulations, since rules for kayaks and paddlecraft often differ from those for motorized boats.

Lower frequencies (50kHz) cover deeper water with a wider cone but less fine detail — good for deep lakes and offshore. Higher frequencies (200kHz) give sharper target detail in shallower water. CHIRP units sweep a frequency range for better separation between fish and structure, and are the better all-around choice if your budget allows it.

Track-mount and clamp-on rod holder systems attach to existing kayak accessory tracks or the hull's gunwale without permanent modification, and can be repositioned or removed easily. Flush-mount holders require drilling and are more common on boats where the mount stays permanent — most kayak anglers prefer the removable, adjustable route.
