I am thinking about getting a kit specifically designed for sidemount. I love and mostly use Apeks rigs and I thought their sidemount package looked nice for routing, etc. Has anybody had good/bad thoughts experiences with the Apeks sidemount rig? Anybody have a different sidemount regulator kit that you like better or I should be looking at?
The Apeks kit is very functional. I have experience with all of the elements of it, but I put them together independent of a 'kit' purchase.
The primary elements:
1. FIRST / SECOND STAGES
Two swivel / turret first stages - Apeks DSTs - with the fifth port
Apeks XTX50 second stages
2. HOSES - SECOND STAGE
A long second stage hose (~7') for the right side, and a short (22") second stage hose for the left, to be placed on a bungee necklace (included with the kit).
3. HOSES - SPG
6" HP hoses for both SPGs.
4. HOSES - LOW PRESSURE INFLATOR
'Custom length' hoses for both sides
5. ADDITIONAL ITEMS
A 90 degree ELBOW / adaptor for one of the second stage hoses
Bungee necklace
My experiences:
I personally prefer swivel / turret first stages for SM. For me, it improves hose routing. I have used Zeagle 50D first stages, HOG first stages, and Apeks DST first stages - all turrets. I like the 5th port option (particularly on the right side, for drysuit inflation), but it is neither absolutely necessary, nor a needless 'bell and whistle'. My Zeagles don't have it. For me, the key is the turret. My two DSTs DO have the 5th port, and I like the feature.
The XTX50 is a good workhorse second stage. For me, it offers venturi control, and user-adjustable breathing - some divers say they are unnecessary features, and they are entitled to their opinion. I have quite a few XTX50s, on tec regs as well as recreational regs, and have no complaints whatsoever. My preferred alternative second stage is a Zeagle ZX - similar in performance to the XTX50.
I personally dive a 7' second stage hose on my right cylinder, and a shorter second stage hose on my left. For me, the left hose is 24", rather than 22" but the difference is trivial. I dive that configuration (LH right, SH left) because I came to SM from backmount doubles, and simply copied my BM configuration on my SM cylinders. There are MANY threads on SB about SM hose lengths. There are some who dive the long hose on the left, some who dive 5' hoses on both sides, etc. That is a matter of personal preference. You won't go wrong with a right long hose and a left short hose on the bungee necklace.
The 6" HP (SPG) hoses are very common in SM - you don't need longer hoses, irrespective of whether you dive with your SPGs 'up' in front of you, or 'down' along the cylinder wall. If you look on Steve Martin's website, he references the Apeks Kit as having 8" HP hoses. On other sites, the Apeks kit is shown as having 6" hoses. Either way, a short HP hose is very practical.
The length of the LP / BCD inflator hoses is also a matter of personal preference. The kit specifications on a number of websites refers to 'custom length' hoses. On Martin's website he makes reference to 'custom length' on one reg but also shows, and refers to, a 20cm (~8") LP hose on the other. Many people like the short inflator hoses, and they work well with the 5th port option on the first stages. I personally have migrated to a longer, 15" inflator hose, but that is really up to you.
Elbows / adaptors are very much a matter of personal preference. I personally use 360 degree Omni swivels on both second stage hoses. I have a 90 degree elbow that I have used, and a 70 degree elbow that I have used, as well. I see no reason to move away from the Omnis.
One of the beautiful features of SM is that it is still in the 'frontier' stage. very little is 'wrong'. A lot is 'OK', or 'right', depending on your preferences.
The Apeks kit is good, but pricey. You won't regret buying it if you decide to go that route.t
