How to insert antenna: Insert the tool and antenna into the round open space in the back of the top cap. Continuously turn the tool clockwise to spool the antenna until the retainer can be replaced (see manual online) -- because im stucked with this method on video :-)
It collects GPS data signals from satellites. Calculates your position and transmits the message "MOB (Man overboard) with your position on the VHF marine emergency frequency.
34m or 34NM is a range it will never get. Its a vhf signal and it travels via a straight line. As you're at the surface the max range will be somewhere in the range of 5NM as the average diveboat is also low to the water. Planes and helicopters or big commercial vessels are able to pick up your signal earlier but dont rely on it. On average we are happy on board when we can make VHF contact to other stations an 17 to 20Nm
Bas Yep i agree with you Bas. All depends on receiving station antenna height (and cable and antenna quality) low antennas on non sailing vessels and fishing boats cant get close to 17nm between eachother unless the other station has good radio gear thats high. Vhf is line of sight. Cheers Bas
Planes and helicopters will not be equipped with AIS/DSC and will not be able to receive it, this device is not a plb and will not transmit on 406/121.5 for air rescue
There is a lot more to being found with this device than pushing a button. Very little is explained, even by the manufacturer, on exactly how your position is determined by other boats. For example, if your dive boat doesn't have a chart plotter or way to interpret GPS coordinates, your dive boat won't be able to get you - your fate is in the hands of a ship that does have the ability to work with the AIS signal this device emits.
You don't anything but a smartphone to follow a GPS location. You don't need internet access. You don't need a map. You are in the middle of the ocean anyway :-). Just find and follow the right direction and you will get to the blue dot.
It collects GPS data signals from satellites. Calculates your position and transmits the message "MOB (Man overboard) with your position in LAT/LONG on the VHF marine emergency frequency. Every ship carries a chart and it's a simple matter of calculating which bearing to use.
IT DOES USE THE GPS NETWORK. It reads the GPS signals and transmits your position on the VHF marine emergency frequency. Ships receive MOB (man overboard) and your position.
Tell that to the divers swept off the dive site in Malaysia (April 2022). They were in the water for three days. The 15 year old boy died. How much is your life worth?

CR123 3 volt. 2 of them, not AAA FYI
Dose it also work for on land ?
It takes 2 CR123A Lithium 3V
I was just looking at these on Amazon, and almost every review said the were water damaged very quickly often in less than 30 ft of water...

It collects DATER? What is DATER?

@@randomstuffguy1731 rescue equipment is equipped with AIS. Even pilot helicopters are equipped with it.
Bought one and it flooded after only 20 dives, become completely useless.
CR123/A batteries

Lol. Got bud ?!
SORRY THIS DEVICE DOES NOT USE GLOBAL POSITIONING SATELLITES IT ONLY EMITS A LOCAL BEACON 34 MILE RADIUS...DO NOT BE FOOLED!

200$ its more affordable to be lost at sea lol
