Yep. Totally understood. Still, 100 dives sounds short compared to the PPS transmitter. Oceanic indicates expectation of 300 hours. Even if that's high, and we knock 1/3 off, the PPS sounds like it's got at least twice the battery life.Transmitter batteries...
They last as long as they last. They're turned on all the time they are pressurised; this can mean many hours or even overnight/weekend/week/month.
Absolutely. My save a dive kit includes 3 transmitter batteries (one for each transmitter), a spare battery for each computer, and lots of orings and grease. I use the rechargeable lithiums in my Perdix, as I can clearly see the battery status when powered up, gives more indication than just the 3 level indicator with some of the battery types.Carry spares with you as they can fail without notice -- especially if using the SAFT batteries.
Exactly. The tool that came with my Perdix for battery changes fits the PPS transmitter perfectly, and the battery can be changed quite quickly and easily.The Aqualung / Shearwater solution is far more elegant. This means the batteries can be changed in-situ, whilst the transmitter's connected to the first stage if necessary.
Years ago, I was on a motorcycle list. For fun, new members were asked to answer a few questions. One was on mechanical ability. It was a 1-10 scale. 10 was something like being able to rebuild an engine using a screwdriver. 1 was "injures self with screwdriver." The transmitter battery swap should be easily handled by someone with a 2 or higher. The 1 might be able to do it as well, but there might be a risk of injury.
