Well DiveBuddyChgo, that’s a good question. The answer: Having over 1000 miles of the most diverse and extreme, bountiful marine rich coastline here at my reach in California, whether it’s in cold, dark , murky, rough beyond limits, with mile+ long hikes over 200 ft drop offs, hour and half distances from the car with no radio or phone contact and earthquakes is why. Go inland just minutes and find awesome altitude dives everywhere. Subtropical Islands within 1 hour boat trips. All year long day or night, non stop. With Hardcore divers that just do it. What gear looks like is not priority. As long as it works or can work to a degree. Anyway the request in this forum was in hopes to get someone interested in digging in the old pile of unwanted regs. Trust me there’s a lot like you that might like the updated new models. So give the old ones a working home! Thanks. If you arrange to send one, I’ll take pictures of how it’s used, and then you’ll understand why!!
