As a diver i like the ideas of this. but if i was to release the cap and activate it, then replace the cap. can this be done under water say 30m ?

Hi, i have one of these i believe that it can't be opened under water because the caseing in depth rated but not working parts inside. it is mainly for rescue if the boat leaves you behind or currant take you away from your boat, if you are worried about getting lost under water you can surface to use it. also not some of the function are not legal use in the UK and some connect directly to to the boat radio sat nav systems id they have right gear. i dont thinkk this one comes with the long life battery you need but they are very cheap buy. hope this helps

What batteries do I need for this

You need 123 cr17345 Duracell lithium 3v. Only I would not recomend this product its badly made and mine flooded despite taking extreme care with it having read similar reviews this. And it did just days out of warrenty. Kind regards Bill.

Failed after a total of 21 dives over 6 months !!

Completed 14 dives on livaboard in Egypt in January, no probs, completed 5 shore dives in Egypt in June, no probs, 3 shore dives in Mexico August Failed. Water has almost filled the battery compartment rendering the unit useless just in time for trip to Galapagos. I have returned unit to supplier requesting refund as you are unable to request a replacement on amazon! Allegedly a refund will be issued on receipt of the failed unit....its only been three weeks since I handed it over to UPS ...`I wonder when I will get a refund :o(

Looks good.

Hope that it is never needed in an emergency but build quality and specifications seem to be excellent. This product would be considerably improved by supplying it with a pouch/case and attachment line.

beware the flood value

loved this, quality looked good, tested and worked, put in drysuit pocket and dived to 50m in quarry tested looks good. however first dive in sea, flooded device doesn't function, dive was in 20-30m. yet to send back to Canada but they state has to be marked of value of 1 dollar for return. had mine for less than a year before failure, o ring seals look good ans screws were still in place when checked. its is piece of mind but recommend regularly checking of seals

Lebensretter im Fall der Fälle

Narrensichere Rettungs-Beacon, die mit exakter GPS-Position um Hilfe ruft, solle beim Tauchen mal was mächtig schiefgehen - und man an die Oberfläche kommt... und das Boot ist ist weit und breit nicht zu sehen. Auf Knopfdruck sendet das Teil dann, wo genau man im Wasser treibt, so dass jeder, der Signal und Position empfängt, zur Hilfe oder Rettung kommen kann. Kein Taucher sollte ohne sein...
