Have a few (
many
) questions.....thx in advance ! to any answer/comment
1. Does the big screen makes a difference ....?
or the watch is too big in the real world?
The screen size is the biggest benefit of this computer. It is VERY well laid out, and super easy to read even on the surface or in bright, shallow water. That being said, I am generally a clear water diver. It also gives you the benefit of very long battery life (over 100 dives is very common). IF you are diving in 5' vis, then a color screen would be easier to read but at much shorter battery life. The backlight is good enough for night diving as well. When warnings appear they show as "inverted" (that is, white text on black background), a great visual alert and very readable as well. Where you really appreciate the screen size is in compass mode. The display is huge, precise, stable at any angle, and roomy enough to also show you depth, time, tank pressure, and NDL. I do a lot of navigation diving and it just can't be beat. I am 56 years old and needed diopters to read a smaller watch style computer. I do not need them to read the Sol. The screen contrast, size and resolution make all the difference.
SOL has some nice features not often mentioned. A very intuitive multi-gas algorithm, and an upgrade to full trimix if you wish. In addition, you can add a very nice apnea mode for freediving.
The compass mode is absolutely without equal. I do lots of navigation diving and it makes nav dives a real pleasure. It is steady at any angle, huge display, easy to set bearings, and roomy enough to easily see depth, time, air pressure and NDL. On nav dives I leave it in compass mode all the time.
I dive with divers who use watch style computers and have looked at their computers. For me, no comparison. I do not like the much smaller round display, not nearly as easy to interpret. Compass mode--just no comparison at all. Trade-off is size. They comment how big mine is and I could never wear it as a regular watch, which is true, but for me visibility trumps everything else and the size also allows for a very large and long lasting battery. Also, I can easily change out my own battery with no need for a trip to the shop.
5. Any known technical problems with the Galileo Luna.... ?
I read reviews from 2012 that it was constantly losing signal with the transmitter?
does Scubapro fix this on 2013 models
I have an "older" style transmitter that supposedly has this "problem". I have never lost the signal, not once. I mount the transmitter on the same side of my first stage as the arm on which I wear the computer (right side, right arm) so it is not blocked by my body. By the way, from what I have read, if the signal does drop, the computer will search and automatically pick it back up again unless the transmitter has completely failed, so it as a minor inconvenience of a few seconds. However I always carry an SPG clipped off to my waist so I never worry about It.
Overall, my thought is that this computer shows all the good things that come from a solid design, top hardware, and years of refinement. It also shows an excellent policy of a company offering constant and MAJOR (apnea, PMG, Tech/Trimix) improvements through firmware upgrade. Scubapro was way ahead of its time on that. The trade-offs (B&W versus color screen, size) are well done and offer substantial benefits.
There was a post above stating that the Sol is "old tec" (implying "low tec"). I do not understand how such statements get posted here. The only difference in technology is color vs B&W LCD. This is a trade off with a substantial benefit (long battery life) and is close to compensated for as to visibility by the screen size and excellent layout.
Other computers don't have "higher tec" depth sensors, buttons, circuit boards, etc. It is just absurd to say so. To compare it to something like the DG-03 is utter nonsense. The algorithm is a standard one (Buhlman Z8 or Z16 if you download trimix mode) and, operationally, the firmware is very advanced for configurability, readability and emphasis on key information.
In fact, the Sol has combined technologies that many other expensive computers don't have, such as the superior compass mode, physiology integration (heart rate) very reliable and advanced gas integration, APNEA mode, trimix mode, firmware updates, and a highly sophisticated dive logging software (unfortunately not Mac compatible unless you have parallels). Some of these might not be of interest to you, but "low tec" it certainly is not!
Hope this helps.
