how are we guaranteed that the transmitter will not mal function? what are some do's and don' ts in using the transmitter
I have about 300 dives on my Suunto D9 from local quarry/cave/lake dives to open sea dives around the world. The only problem I've had with the D9 transmitter failing is when I switch to dive mode and I'm next to another Suunto transmitter and actually pick up the signal from that receiver instead of my own. Once you get away from the other transmitter, the D9 will show a "fail" alert notifying you that it is no longer getting a signal from the transmitter. You can surface, reset the transmitter code on the D9 so it tries to find another transmitter. This is not usually a problem except on a boat dive with 20 other people. Even then, it's only happened 5 or 6 times.
I love this watch. Fair warning though. LeisurePro is not an authorized dealer and can offer NO factory warranty other than their own warranty. A recall on the D9 required service and although LeisurePro did do the service, once the offered warranty period is up, the unit will become useless if a recall or service upgrade is needed. You can get batteries changed but no major service. The serial numbers are not recognized. I like this watch so much that when/if I need a major service or programming upgrade, I will buy a legitimate version again.
Hello Peter, there is no guarantee that the transmitter will not give inaccurate readings at times. If you know a dive site well as well as your average air consumption at different depths you may not feel that you need an accurate reading the entire dive. And the transmitter may (read will most likely) cease to function if you dive often.
Many D9 users and all advanced wreck/deep/tech divers eventually return to good old fashioned spg, and can the transmitter.
The D9 I purchased has broken down several times - replaced twice by Suunto and the last one gave inaccurate readings after a battery replacement . The authorised Suunto shop says the module is faulty and it will cost over 500 $ to replace, the same repair expert (Whitetip divers Manila Philippines) said that Suunto only rates these for 500 dives before they fail or need full overhaul - this sounds ridiculous for a dive computer at this price but if you dont use it too much it is nice jewelry.
I still like my stinger which after about 8 yrs has had a $120 overhaul and still works good, albeit put through alot less dives per year than the D9.
Hope this answers your question - Happy Diving
