KSUN TFSI VHF Marine Radio — Floating IPX7 Waterproof

The KSUN TFSI Handheld Two-Way VHF Marine Radio is a floating, IPX7 waterproof marine transceiver with NOAA weather alerts, international channel access, and dual/triple-watch monitoring for safer time on the water.

Compact and purpose-built for boating, kayak fishing, and coastal operations, this KSUN TFSI portable marine radio blends rugged water resistance with practical features like fast charging, included rechargeable batteries, and a backlit display. It supports international VHF channels, provides weather channel access and alerts, and is designed to float and drain if accidentally dropped overboard.

How does the KSUN TFSI protect my radio when it falls in the water?

The radio meets IPX7 waterproofing, so it withstands submersion to 1 meter for up to 30 minutes. Its buoyant housing brings it to the surface quickly, and the vibration drainage helps expel trapped water to speed drying and recovery.

• IPX7 rating: 1m depth for 30 minutes
• Buoyant design that floats immediately after immersion
• Vibration drainage feature to remove residual water
• Salt- and corrosion-resistant materials for marine environments

What power and charging options are available?

This model ships with five AAA Ni‑MH rechargeable batteries installed and comes with both AC and DC chargers for flexible recharging—onboard or at shore. Using the included cables and adapter ensures optimal charging speed and battery life.

• Includes five AAA Ni‑MH batteries ready to use
• AC charger for home or dockside power
• DC charger for charging from a vessel’s power supply
• Fast-charge compatibility when using the supplied adapter and cable

Can it keep me informed about changing weather at sea?

The KSUN TFSI provides NOAA weather channels and alert functionality so you can receive forecast updates and severe-weather notifications while underway. This feature helps you plan maneuvers and make safer decisions when conditions shift.

• Dedicated weather channels with alert mode
• Automatic reception of weather bulletins and warnings
• Alerts pass through even when monitoring other channels

How does dual and triple-watch improve communication onboard?

Dual and triple-watch modes allow the radio to alternate monitoring across the selected main channel plus priority channels, so you don’t miss a call on the main working channel or the international distress channel. The radio supports 16 standard VHF channels and a designated talk channel for routine use.

• Dual-watch and triple-watch for simultaneous channel monitoring
• Access to 16 VHF channels plus a talk channel
• International channel compatibility for coastal and offshore travel
• Backlit display for low-light and night operations

It’s especially useful for recreational sailors, fishing enthusiasts, and anyone who wants reliable marine communications and peace of mind on the water.
