Full kit ships with a primary lithium battery, a rechargeable lithium-ion pack, and a charging base. IPX7 waterproof, glove-friendly, and certified to IMO and SOLAS carriage rules.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe SR303 is the radio you hope you never have to use. It's a handheld GMDSS VHF built for life-raft packs, abandon-ship bags, and the worst day you'll ever have on the water. When the boat's going down and you need to talk to a rescue coordination center or a nearby ship, this is the unit that keeps working. It's certified to meet IMO and SOLAS regulations, so it satisfies both mandatory carriage on commercial vessels and voluntary carriage for cruisers who take offshore safety seriously.\u003c\/p\u003e\n\u003cp\u003eHere's how the batteries work, because that's the part that matters most on a survival radio. The full kit ships with two of them. The primary is a lithium battery with a witness label across the seal. As long as that label is intact, you know the battery has never been touched and it's ready for an emergency. Pull the label, connect the battery, and the radio auto powers on and drops straight into GMDSS mode with channel 16, volume 8, and squelch 2 already set. No fumbling with menus while you're treading water. That primary battery holds its charge for a five-year replacement interval, so it sits in the raft pack ready to go.\u003c\/p\u003e\n\u003cp\u003eThe second battery is a rechargeable lithium-ion pack, and it comes with a charging base. That's what makes this the full kit rather than the emergency-only version. You get a radio you can actually use day to day for routine bridge-to-bridge and dock calls, then swap to the sealed primary battery for the raft pack. Two batteries, two jobs. One thing worth knowing from the offshore crowd: lithium-ion packs lose a little capacity after a couple of seasons, so plenty of long-range cruisers keep a fresh spare primary on hand for extended passages.\u003c\/p\u003e\n\u003cp\u003eEverything about the SR303 is built for a bad situation with cold, wet hands. It's rated IPX7 waterproof, so a dunk won't kill it. The whole thing is sized to work while you're wearing survival-suit gloves, and both the digital display and the keypad are backlit for low light and nighttime use. There's also NFC built in, so you can tap the radio with a phone to pull up the battery replacement date and product info without digging through paperwork. Operating temperature runs from minus 20 to plus 55 degrees Celsius, with storage down to minus 30, so it holds up whether you're in the tropics or running north.\u003c\/p\u003e\n\u003cp\u003ePhysically it's compact, 63 by 150 by 33 millimeters and about two-thirds of a pound, so it fits standard life-raft mounting pockets on sailboats in the 30 to 45 foot range without eating up space. A couple of install notes from the field: the supplied bracket does the job on a console, but on a fast planing hull you'll want to add a fastener or two so it doesn't shake loose in chop. And if you're mounting it in an environment where you swap batteries a lot, keep an eye on the waterproof seal and refresh the O-ring periodically. That's just good practice on any sealed handheld.\u003c\/p\u003e\n\u003cp\u003eStandard accessories come with both the emergency-only and full-kit versions: a flexible rubber antenna, a belt clip, and a wrist lanyard. For full offshore compliance, the SR303 sits alongside a registered EPIRB and a fixed-mount GMDSS VHF at the helm, covering your handheld distress comms end of the picture. We're an authorized dealer, so you get the full manufacturer warranty and advice from people who actually rig safety gear for a living.
