...geez Loise a couple of senior divers get worked up on the use of the word hat lol
glad to see the rest of my post was spot on lol
...in the world of working divers (and these two divers know it)the term hat is in reference to the head gear a commercial diver uses , back when i started tending the divers even navy trained referred to their Jack Browns as a "hat" I guess the term has evolved to mean only "hard hats" lol I shall make a note of this for future reference. As for their use or need today. The heliox18 or known presently as a kmb18 is still widely accepted even these two older models are quite viable. As for their demise in the oil field here in the states ... if not for a few idiots placing the hood to frame incorrectly they would still be in use. "Company policy" is what knocked them out, hell, I believe KM started producing the new hoods and retainers to improve and show their viability to offshore companies. Sadly, a day late and a dollar short as they say. Head protection can be some what improved with the purchase of the hard shell accessory . Com issues with these "hats" is directly related to the integrity of upkeep as in proper comm units, a sound hood and sealing at the face makes them just as good as a "hard hat", ya I said just as good lol I am sure I will get a flogging for THAT statement, LOL just make sure the cat-O-nine is fresh.
Personally I am not a fan of km , i own and maintain a few including a 18 damn thing never feels solid (they tried to improve this with a "comfort" insert *bah*)...NOW, a solid feeling bandmask was/is a General Aquadyne dm6 that f'er "locks" to your head and damn comfy, having the face seal mated (glued) to the frame made it so. Sadly the dm6 comms are something to be desired (read high maintenance). WAY to many breach points WAY to many lol. mine still produces money from time to time. LOL
Scuba one - I believe the amount your asking is makeable (is that a word? spell ck just exploded)... personally, I would sell separately.
...fyi - on fleebay a newer console the last time i checked was at a bid of 600 and a couple of heliox 18a's (yours) sold at around the 1100 mark - one more thing... working divers are notorious for turning our noses at a price and making a low ball offer sound like we are doing you a favor. Never met one including myself who wouldn't jump at the chance to have bragging rights on how little was payed bwaaahahaha
