trim

Hello everyone, (long-time lurker, first-time poster). Background: I am a diver from Czech Republic, OC, highest qualification would be Cave. Mostly diving dams or freshwater lakes nearby. I usually switch between SM and BM, but the question is only for open water "deep" (40-50m) dives...

Certification continues to elude me as of now standing water behind my eardrum will not drain. I've seen a doctor and have taken a decongestant with no relief. I see an ear, nose throat specialist next week, hopefully I can return to the certification process. In the pool when I am 12 ft under...

Hi Divers! I was always diving with hiring gear and just got my First own bcd. Its a wing (Cressi Commander) and I know the Buoyancy and trim is different with a jacket style bcd and despite that I'm not sure if it's the commander, if it's a faulty bcd or if it's normal but: I got a perfect...

I am wondering if anyone has any experience with the XDEEP Hydros 40 wing. I am about to pull the trigger to switch to Halcyon, but thinking of it as an alternative being $200 cheaper ($339 vs $540). Main concern I have about the Hydros wing is that they state they reduced the volume of the...

I have a upcoming Trimix course in September so I’m practicing diving with two deco tanks. Before this I used to carry either an AL80 or AL40 for deco, which I hardly notice through the whole dive. I like the idea m carrying both tanks on my left. However, I had some trouble with my trim with...

Hey guys, I just started diving twinset. Before that I did most of dives using sidemount since I did a lot of my dives in caves. I read many threads on this forum about twinsets. I found a lot of people think stability as a pro for backmount double. But I found my double 'rolling' on my back...

I'm taking a PADI Divemaster course and I see all the skills and tests are demonstrated in a knees-on-the-floor position. I always make a point of keeping good horizontal trim and minimizing contact with the floor (be it in a pool or open water) so not to damage corals, the equipment, stir up...

Question for all the trim gurus out there. I currently use 10lbs total in saltwater. 2 lbs each in my bcd trim pockets (up high on the hydros pro) and two 3 lb weights on my belt. I have a trip coming up in February and want to try to get rid of the belt (its a pain in the ass with a crotch...

I have a Zeagle Stiletto BCD with integrated weight pockets and rip cord release. One issue I have experienced with this system is that weights in the integrated pockets are not fixed and tend to move around. It's not really an issue as long as I stay in the same position, but if I turn from...

Hi I'm from Taiwan and sorry for my poor English lol. I'm in a ow course now. It's paid from my aunt because she wants me to be her buddy for trips in the near future. My coach is very strict and he wants his students to practice more. Thanks for that I could go to his swimming pool for free...

Hey Folks, I'm looking for some feedback. I dive in British Columbia Canada most of the time, and it's cold here so I have a lot of exposure protection. I wear a full 7mm wetsuit, with a 7mm shortie overtop. Keeps me nice and warm. Typically I wear about 40lbs of led. 14 pounds on my weight...

Perhaps the best propulsion (swimming) technique in Scuba Diving is the Frog Kick. Compared to the Flutter Kick, the Frog Kick is more efficient. It is a “kick and glide” motion that conserves energy while delivering a powerful thrust to propel you forward. It is also very effective. Notice...

Back to basics sounds easy doesn’t it? Having plenty of dives, being current, many technical, on open and closed circuit, you’d think GUE fundamentals would be fairly easy and just polish off what you probably think is a reasonable diver to begin with……………….I wish! “Back to basics” is true...

This is a video of my PADI AOW student learning how to deploy a DSMB in strong current conditions while maintaining position (vs drifting). I thought I'd share this with the community to help new divers learn this essential skill. The video includes a step-by-step "how to" of the skill...

For staying still, horizontally, mid water, what is the best form of that position? The position I have in mind is typically called the skydiver or frog kick position. In particular, how far up should the knees be bent to give the easiest control of body position. There are some knee angles...

This Satuday I hung a 24" glass free convex safety mirror from a swimmers starter block in a pool about 2 feet above ground (string to starter block, weights on bottom). Except for the initial kiddy soccer effect (all in one hive around the ball), it worked pretty well for instant feed back on...

Hi all, newly minted OW diver here, took the chance to ingrain all the basic skills and tried some other more advanced skills in the pool after my certification. Had success in trying out frog kicks, back kicks, helicopter turns, and holding my position relatively still in the water, but was...

Here's an illustrated article that I wrote to help sidemount divers struggling with cylinder trim issues. I hope it can benefit some people. Any comments and feedback for discussion would be good... or anyone with some better illustrative examples/photos, please do let me know. Ultimate Guide...

I'm selling my wife's Zeagle Zena (size S) and my Hollis HD100 (large). Asking $300 for the Zena and $250 for the Hollis, plus shipping. Both are back inflate buoyancy compensators with integrated weights, quick release tank straps, and added trim weight pockets. They're in good working order...

I know some/many of you may have seen this type of talk/demo before in your training...but this is a vid I made this year for our divers to reinforce proper trim training for open water/advanced students...Hope this helps someone! In this video, we explain/demonstrate the how to achieve and...
