Radar alarm Systems ?

Quickly a Question? do Radars have Alarm systems? IE I'm fishing solo and fall asleep is there a Claxon !!! setup to wake me if another boat is on a collision coarse, Or is that tied into AIS?

I have programmed my Navnet before to sound an alarm if an object comes within a radius that I choose, normally at least five or more miles. I don't know if there is a collision alarm on average radars.

Thanks but I think I have the answer It is another bit of kit, AIS it has it all built in. The B (receive only ) level as far as I can see generally dose not, but all the A level ( send and receive ) seem to have.

I have an early 1980s vintage Furuno on Avenger and it has what they call a "Zone Alarm". You set up a marker at whatever range you prefer, and it will sound an alarm if a target enters that range.

You can sometimes look at manufacturers websites and download manuals for specific models. Then you can see what features they offer. I think that by the late '80s most radars offered similar features.

Receive AIS will give you a tone at about 1/2 mile, not much warning. Radar can be set for what ever guard zone you choose.
