Hollis Katana 2 Sidemount BCD
Hollis recently unveiled its newest sidemount offering: the Katana 2. The new model supersedes both the Katana and the SMS 50 when it comes to Hollis’ dedicated sidemount harnesses and bladders.
Here are our key takeaways when we looked at the differences between the Katana 2 and Hollis’ other sidemount offerings.
The Hollis Katana 2 Key Specs & Features
- H and Y harness configurations possible
- 40 lbs lift capacity
- 20 lbs weight capacity
- Quick Fit System (QFS) ‘one-size-fits-all’ design
- Single bladder and dual bladder options
- Integrated mount for sidemount CCR
- Two dump valves – one top and one bottom
- Optional preconfigured SMS regulator kit — DCX 1st and 200LX 2nd stages, LP and HP hoses, two brass SPGs and a regulator necklace — for an additional charge
- Two-year standard warranty
What We Like
- Because the unit can be purchased with a preconfigured regulator kit, it can be useful for both beginners and experienced sidemount divers
- The unit is easy to adjust and tweak to your preferences
- The wing wraps around the diver’s body more which ensure a smooth streamlined profile and eliminate any “turtling”
- A good amount of lift
- The Katana 2 is really bridging the gap between what’s often known as the British/Mexico and American/Florida sidemount schools of thought.
What We Don’t Like
- This is a Sidemount only BCD. But if that’s what you’re looking for, then the Katana 2 from Hollis is a great option.
Should you buy the Katana 2?
The Hollis Katana 2 is arguably one of the absolutely best sidemount BCDs I’ve tried. It fits perfectly with all variations of sidemount diving – whether you’re into advanced cave diving or a sidemount beginner.
This side mount BCD provides minimal water resistance and great freedom of movement even in the smallest conditions.
The Katana 2 has 8 well-placed D-rings + 2 buffer D-rings: one on each shoulder, one on each hip/shoulder strap connection, two rear rings, one on either side, two on the crotch strap, and two extra D-rings to place where you want.
All the D-rings (except the two on the back) of the Katana 2 can be moved or removed as you prefer, giving you the ability to adapt your setup the way you like it.
This is a “One-size-fits all”, with a Quick Fit System (QFS), which means I can adjust it to fit me (6.5-ft tall) and we could make it fit a girl at 5.2 feet. This BCD is highly adjustable for any set up you’d like.
“Depending on location, everyone’s a little bit different about how they like to set their harness up. But at the end of the day, the coolest thing about the Katana 2 is that you can run it however you want. “ -Hollis Brand Manager Nick Hollis
The Katana 2 BCD is easy to balance for a perfect trim, I think I got it on the second dive. You can’t do much in the water, but once you found the perfect setup, It’ll stay in place. There are 4 “spine pockets” each with slots for one 5-lbs weight, and the bladder wraps nicely around your body which makes a low profile. The Katana 2 feels like part of me from the second dive.
Hollis Katana 2 is Only Sidemount
The Katana 2 is distinguishable from the SMS 75 in that it’s a dedicated sidemount unit. The 75, on the other hand, is made for both sidemount and back-mount diving. If you’re looking for a wing that can act like a traditional BCD and do sidemount double duty, the SMS 75 is the option for you.
But if you’ve given up back-mounted diving for good and are after a sidemount-only wing, the Katana 2 could be the ideal option.
The Difference Between “Y” and “H” Sidemount Wings
The Katana 2 has been designed with flexibility in mind. With that in mind, the newest Katana can be set up as a “Y” harness or an “H” harness.
You can think of the different styles of sidemount harnesses as related to the waters they were designed to be used in and the kind of tanks used. In warmer waters, divers typically favor a Y configuration with the harnesses running over the shoulders much like a traditional BCD.
But when divers have heavy steel tanks (often used in colder water) having the weight of the tanks evenly dispersed across the central part of the torso is useful. This is the “H” configuration, named because the harness runs straight down to the waist strap forming an H shape. The H configuration is also easier for divers in drysuits to don/doff the rig because of the larger harness opening
The Katana 2 was designed with warm water, aluminum tank diving in mind, but thanks to what Hollis is calling their H Style Accessory Kit, the Katana 2 can be configured for cold water, steel tank dives.
