Found this off West Welch Island in 61 feet; really can't tell if it's a safe or a frig; if it's a frig it's built like a tank and would stand at least 5 feet high-that would be some frig; the lower part of this thing has some odd stuff suggesting a frig but a safe could have something similar depending on its level of sophistication.
