Mobi-alert system

[Quintessa]

Has any one got one of theses systems. To me they seam the best as all other systems go back through your GPS and then into your plotter to activate your MOB on the plotter. Traveling at 10 knots by the time you get your mob alert you could be 200 to 300 meters down the track and that is a big area to find someone at night in a big sea.

This mobi alert system seams to react immediately. Am I correct in this assumption ?

Look forward to you responses.

I just chucked my system in the trash bin. Obsolete and bankrupt.

Ouch. Did you replace with any other MOB system?

Not yet but it's gonna be the new personal AIS beacon, probably from McMurdo. That is in addition to a personal locator beacon (also McMurdo, the small/cheaper one)

We only use these gadgets when one is sleeping or otherwise occupied inside and one is standing watch.

A nice addition if you can stow it but:

Quite large
Has to be manually activated (shares this limitation with personal epirbs)
Only effective for 4 mile radius.

Tempting I agree but the Mobilert system might mean quicker turnaround and recovery. Ideally would have both I guess. Maybe a personal VHF which could be tracked would be more useful. CAN VHF be used for direction finding (with the sort of small package RDF machinery which used to be available for HF??

AIS *is* VHF. 4 miles is way enough because you are well within that when crew falls overboard. Mobilert only warns you: personal AIS warns you plus very other AIS unit around.

There is an automatic version too... McMurdo does that with a lifevest maker, Google will find it.
