^^^^^ couldnt agree more you beat me to it
and I think few of you are missing the point........... a kite is not an appropriate craft for venturing far out to sea...
I personally have an EPIRB (I take it when sailing ( ocean ) as a backup as there is one permanently in the boat ) I have never had to use it as the yacht is a purpose built craft for going out to sea...... we have had gear breakages and have had to use the motor to limp to port, we have had to use a sea anchor overnight before being able to conduct repairs to rigging. I would only use the EPIRB when all other avenues have failed and it is a matter of life or death... eg: you have no other forms of communication and or you are in the life rafts and adrift
I also take the EPIRB in my 4x4 but again we also have a UHF and HF radios and travel with another vehicle when in remote areas eg:The Simpson etc.... We also carry enough water and food should we need to stop for a few days to conduct repairs.... again have never had to use the EPIRB and could only imagine using it in an emergency ie : remote car accident and no other forms of communication.
An EPIRB is not a primary form of communication it is a locating beacon for an emergency only. If you go to sea you have to take a certain responsibility for your situation. On a kite far offshore broken gear or a drop of wind means an immediate emergency.
If you are kiting out at sea you have no ability to care for an injury, you presumably have no food and or limited water and are completly exposed.... imagine someone riding a pushbike out into the simpson desert with no water, no food no tent just carrying an EPIRB you would think they were an idiot.
The reference to hikers completely misses the point......You would have food, water and shelter and could survive extended periods of time even with a serious injury ie: broken leg.
Other issues include : EPIRBs have been known to fail, a rescue could take many many hours...... ( how long will you survive immersed in the water ).
Im not against adventure Im all for it and have done plenty of it... but Im about doing it properly and being prepared. If you venture far away you must be properly prepared which means an appropriate vehicle or craft fit for the purpose, ( a kiteboard is not an appropriate craft for travelling at sea) and be prepared to have some sort or self rescue or contingency plan.
By all means if you want to attempt some sort of crossing on a kite ie: Tassie to Victoria as some have done make your own arrangements for a rescue/chase boat and take every precaution. An EPIRB should not be your primary form of communication it is last resort.
