Well now, i didn't expect all this. Okay, i know now (if i had any doubt before) that a mechanical spg is more reliable than a wireless spg. I know that eliminating a hose for a wireless guage is arguably "hogartian" depending on your definition. Apparently there is more than one definitin for hogarthian though, considering this thread. Some say it is minimal gear, some say it is simple gear, and there is quite a difference between the two. Then there are the hybrids, who consider it minimal simple gear.... So i have decided that until i have tested faith in my Vytec, i will be diving with it and an spg and comparing the two during recreational dives. Once i am used to my computer and have seen firsthand it's performance in a vaiety of cold murky conditions (where i dive), if it is satisfactory, i will be diving with just my comp during rec dives, and adding an spg for redundancy during wreck dives or anything like that. Thoughts? And i'm sure there will be plenty... I welcome all though. that's why i asked this question here, among more experienced divers. Honestly, i think the people who disagree with me might even be more helpfull!
