I went side mount for back injury reasons, close to 75 dives in this config and it is my go to for how and where I dive. Would I dive back mount doubles , never, so it must be terrible for everyone else to try and I condemn it :)

You know, because my beliefs and the way I dive are the way everyone should dive.....
 
Unless you are cave/adv wreck diving i don't see any major advantages to using sidemount, at least in S FL. I can easily manage the valves on my twinset, some divers even mount the tanks up side - down to get a better reach. I have tried SM before and may have to again going into full-cave, but it some how just feels, loose, it doesn't have the same "connectivity" as bp/w.....the tanks are constantly moving and spg's are floating around, and doing any kind of kick besides frog is a nightmare <TG>

:facepalm:

Lots of folks with knee/ankle/back issues dive SM. When I was getting fills yesterday, another “older” diver (I’m 52 and he looked older than I am) mentioned his knees can’t handle the weight of a twinset anymore and he’s switching to SM. His seeing my SM rigged tanks prompted the conversation. I’ve got bad knees/sciatica myself. Couldn’t handle the weight of small doubles.

Are you another of the mindset that twinsets are the only “real” way to dive and anyone who settles for SM only is somehow an inferior diver? You certainly give off those vibes. Maybe we should make you handle a twinset with a bad knee.
 
Suddenly a large number of side-mount haters appear! (hah)

I'm going to give side-mount a solid try before forming any strong opinions on it. To the best I can tell, SM being better or worse is highly subjective or based on one's individual circumstances, or the type of diving.

I just signed up on sidemounting.com, and bought a harness and wing (without breaking the bank). So it would be kinda silly for me to dip out now. At minimum it should be a learning experience, and I'll be a little more prepared if I later wanted to get into tech-diving or cave-diving, or just quickly mount a pony bottle. I suspect SM would work well for me, but I suppose I'll find out one way or another.

I also usually dive from the shore, or my friend's boat, so I don't have to worry about being "that guy" who blocks the ladder. I do scuba for fun, and don't blame people if they want to relax a little and take their time, unless they're absurdly slow.

good deal! I believe a vast number of divers who don’t like sidemount had a bad experience with being “trained” by someone who didn’t know what they were doing, resulting in a feel of instability and unnecessary complication. When done properly, sidemount is stable and intuitive.
I commend you for signing up for a proper class and entering with the right mindset.

Sidemount seems like it could have plenty of uses. The reasons I'm attracted to it are, it appears that:
  • The configuration of the OCTO looks a LOT cleaner & I hate having hoses everywhere.
  • Easier to both attach and detach tanks.
  • Theoretically easier to get in/out of my friends boat. Possibly less likely to injure my back climbing up a small ladder in wavy conditions.
  • Supposedly more streamlined.
  • Good for quickly attaching a redundant air-supply.
And many other people mention it being great for if you have problems with your knees, back, or other joints.

Thank you. I'm excited to get started. This week, I'm knocking out another SCUBA class, and then next week is when I'll probably enter the water side-mount for the first time.
 
May i ask why you consider it a “cluster”?

Thank you, of course you may.

Solo is diving unhindered where on goes minimal basic gear and the diver just goes

unless you are here


Magnificent!

or you are Marie13 with knees (I actually included you Marie, during my compilation before reading your posts)

anyone that thinks this way must have intermittent electrical issues up top


Solo is for ease of diving, because all the rest with all the gear is not diving

you seem to believe that sidemount looks like the second picture unless you are the truly elite? Perhaps you had a poor experience trying it? Or are repeating what mentors have told you without asking the reasons they came to that conclusion?

this is what i look like

As you can see, it doesn’t have to be a cluster if good training is involved. He came out of the water asking why people made it sound so complicated, and saying it was very intuitive and felt great.
 
I have done 120 dives since Christmas. I brought my back mount rig and my sidemount rig. I have not used the back mount rig once but visiting friends have. I usually dive with two 80s on the sides and one slung in front. I dive with other side mounters and with one guy that is back mounting doubles and slinging a stage and with some friends in single tank back mounted and a slung stage.

I use a scooter and often pull others as they hold onto my waist strap. There is significantly more drag when pulling even a single tank back mounted diver compared to a side mounted diver. The sidemount tanks are in the same plane as my shoulders. Look at the picture above of the sidemount diver head on. You can't see his tanks. Imagine the extra drag if you put one or two tanks on his back sticking up above his frontal area that creates the drag in sidemount.

There are downsides to sidemount diving but the ones that are regularly raised by those that haven't used the configuration or have only tried it and rejected it are not problems that exist for a trained side mounter. My biggest issue with sidemount is that if my aluminum tanks are near empty and I have any reason to want to remove my rig underwater it will be SIGNIFICANTLY more difficult than with back mount because the floaty bottoms of the aluminum tanks are going to turn the whole configuration into a mess once the rig is not attached to you which means stowing hoses and disconnecting tanks and clipping them off and it's really just a mess.

Fortunately the reason to do that in back mount so that you can inspect things isn't an issue in sidemount because it is simple to dismount a tank and remount it. If, however, you ever have the urgent need to perform a warhammer maneuver, I recommend just soiling your suit and working it out later. It isn't possible in sidemount with a wetsuit. It just isn't.

When I exit the water I already have everything stowed except my short hose in my mouth. I hand up the scooter, camera and tanks as quickly as the person taking them is ready to take them when diving a boat in cozumel. I can go up the ladder with two tanks but doing so after clearing deco is not the optimal thing to do. On shore I have someone take them out when possible but I have come out and climbed stairs with three tanks and a scooter.

My sidemount experience is limited to boats in Cozumel and the UAE and shore diving with aluminum tanks in the ocean and steel tanks in fresh water at home. I won't sell my back mount rig but I don't dive it either. I think I would take it for a single tank night dive but see no reason for it other than that and diving in the river.
 
Hi @RayfromTX

Your configuration is perfect for the diving that you are doing, where you are doing it, with the support available to you. Your current opportunity may be relatively unique and not readily generalizable. You could probably do something similar in Bonaire, perhaps you'll have the chance to try it sometime

Take care :)

Quality instruction makes the difference and not everyone likes it. It has it's down sides as well and I imagine dressing on a boat is one of them but unless you give it a legitimate try, beyond a course, you won't know if it is for you.
