So we will have some &#8216;flashbacks&#8217; from now on in this blog.<\/p>\n<p>To give a slight bit of timeline, I was offered AOW with SPLASH down in Placencia, and I completed that in the spring of 2013, spending just shy of 2 weeks down in Placencia, mainly diving, and fending off some nasty cold\/flu\/fever that was going around the villages.<\/p>\n<p>I also spent 2 weeks in Puerto Rico at the end of August, spending under half the time diving, and the other half topside.<\/p>\n<p>After that trip, I decided that I really want to own my own gear, to give myself some consistency, and to help with getting out and diving locally.<\/p>\n<p>I spent a while on EBay, looking for reg sets, and BP\/W to go up at a decent price, but it didn&#8217;t happen for me. Instead, I put up an ad in the classifieds on\u00a0<a href=\"http:\/\/www.scubaboard.com\/\">Scuba Board.<\/a>\u00a0Later that week I placed an order (coinciding with Black Friday) with\u00a0<a href=\"http:\/\/www.udmaquatics.com\/\">UDM Aquatics<\/a>\u00a0for a whole whack load of HOG equipment.<\/p>\n<p>I spent an evening, putting the plate together and adjusting it for use with a wetsuit.<\/p>\n<p>Later that week, I found a barely used Whites Fusion dry suit, and purchased that as well. It&#8217;s important to note, I went with a SS plate, for the drysuit.<\/p>\n<p>I only know a bunch of vacation divers here in town, so I put up an ad on facebook with one of the local groups looking for a buddy to go hit one of the pools in town. So having setup a buddy for the pool, I set off to get some last minute supplies (like some more bungee for my backup reg, some weights &#8230;. ugh &#8230; more on that later).<\/p>\n<p>Getting to the pool, we suit up, and not quite knowing how much weight I need, I started with 10lbs on a belt. I normally use 10lbs on a belt with a 3mm shorty and a jacket BC. Well, let&#8217;s just say, as soon as I let a little bit of air out of my full wing (32lb), I quickly started sinking. OK, well, I&#8217;ll drop it down to 4lbs then! I thought ..<\/p>\n<p>Second attempt with 4lbs of weight (in my 3mm shorty, with SS plate), and down I sink! Hmmmm, what about no weight belt?<\/p>\n<p>OK, no weight belt, get away from the edge of the pool, and get that same sinking feeling. Yup, the plate is too heavy itself! Well, I&#8217;ve got nothing else to do to make it lighter, so might as well figure it out.<\/p>\n<p>So plummetting down to the 5m depth of the pool, putting air into the wing, I end up crashing into the bottom, while still holding down the inflator button. After a few more big bursts of air, I have gained some bouyancy, so I dump a little out, and spend the next minute or two, adjusting the air in the wing so I&#8217;m no longer sinking or flying to the surface.<\/p>\n<p>I reached back to feel how much air was in the wing, and it felt like quite a lot!<\/p>\n<p>Well first goal achieved for the day:\u00a0<b>How much weight do I need to add?<\/b>\u00a0<i>Nothing, unless I have some anti matter!<\/i><\/p>\n<p>And off to the second task I have:\u00a0<b>Whats my SAC rate?<\/b>\u00a0So coincidently, I looked at my new gauge before I started the trampoline experiment of weighting and I started with a 210BAR tank. Swam around for a while, picking up stickers and other paper\/plasticish items off the bottom of the dive tank for about 10 minutes, looked again and saw that I used up around 30BAR of air and decided to surface.<\/p>\n<p>So for 10 minutes, I breathed 30BAR from a 11L tank at an average depth of 4.3m, means that my SAC rate is about 20L\/minute.<\/p>\n<p>Alright, time for my next tasks, practicing some regulator recoveries, swapping to my back up reg, and clipping of my primary reg. This all seemed to go well, a few times, my right D-Ring wasn&#8217;t where I thought it would be, or my backup light moved up the webbing and pushed it higher towards the top of my shoulder.<\/p>\n<p>Around that time, a few other buddy groups splashed in the pool, one looked to be an OW\/AOW course, and the other &#8230; maybe they should have done a refresher &#8230;.<\/p>\n<p>Sadly, another OW instructor doing everything on the knees with the student, even some weird things like swimming lengths with 1 fin, no reg or mask &#8230;. bit of a weird combination, but if I were to be missing a fin, mask and no air, you bet I&#8217;d be looking to my buddy for their long hose and ascending! The only good thing I saw (and that&#8217;s marginal) was that they were doing fin pivots at one point (hence the AOW part ..)<\/p>\n<p>Near the end of the session, I decided to give the SMB a go. Needless to say, after a few months of not shooting one up (or rigging one), it was a comedic effort. My buoyancy was pretty decent while rigging and shooting the bag, but winding up the slack I floated up a little bit. The second attempt was better, I didn&#8217;t end up tying a knot in the spool, and shot the bag with little difficulty.<\/p>\n<p>On the surface, had a quick chat with one of the lifeguards who has never seen a SMB before, let alone one deployed in the small pool.<\/p>\n<p>Overall a success in many accounts, and failures at others. I spent the afternoon going around to a few dive shops looking for weight, and was successful at the last shop (one was closed, the other two didn&#8217;t have any weights). Which brings my to my biggest pet peeve about this diving industry. WEIGHT. I&#8217;m talking about what we use to make ourselves less buoyant, and body weight\/fat. With most boat charters, the DM&#8217;s always question how little weight I need (I&#8217;m a hefty 225lb 5&#8217;11&#8221; guy with great balast in a match of tug of war&#8230;) When I tell them I usually only need 10lbs with a 3mm suit, they play the &#8216;how much do you weigh game&#8217; and try to get me to wear 18-26lbs of lead! I&#8217;m just hoping that the drysuit warrants the amount of weight I purchased from the one dive store who wouldn&#8217;t listen to my weighting requirements &#8230;.. (and it&#8217;s the only store that sells BP\/W setups as well as do TEC training &#8230;.)<\/p>\n<p>In other news, my drysuit is in, but at the post office. I won&#8217;t be able to pick it up until the new year (out of town, and it&#8217;s not available for pickup until after I&#8217;m gone).<\/p>\n<p>Happy Holidays<\/p>\n","protected":false},"excerpt":{"rendered":"<p>No, I didn&#8217;t stop doing anything for 15 months, instead I&#8217;ve been posting my diving experiences on the days they[&#8230;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[6],"tags":[],"_links":{"self":[{"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/posts\/38"}],"collection":[{"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/comments?post=38"}],"version-history":[{"count":1,"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/posts\/38\/revisions"}],"predecessor-version":[{"id":39,"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/posts\/38\/revisions\/39"}],"wp:attachment":[{"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/media?parent=38"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/categories?post=38"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.bradharris.ca\/UnderwaterAdventures\/wp-json\/wp\/v2\/tags?post=38"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
