Depth 200 feet (60m), deco obligation 48 minutes and your buddy just signaled that his O2 bottle is empty! This deep drift dive has just become a bit more complicated. The dive plan was for a 25 minute bottom time and 48 min of deco. However your buddy now has a 76 minute deco obligation and no gas to do it with! You are now in real trouble.
You planned ahead and are prepared for emergencies so a dingy with extra deco gas is following the team’s bubbles. But how do you signal the boat to ensure the spare gas so desperately needed will make its way down to your deco hang? The yellow Surface Marker Buoy (SMB) is the answer.
Wreck divers who dive in strong currents send up orange SMBs as a matter of course. This lets the crew up the top know where the divers are drifting as they complete their deco. But it does not alert them to an emergency down below. Sending up a yellow SMB will ensure an instant response and assistance from the crew. The chase boat can now send a safety diver down to assess the situation and bring extra O2 to your buddy. Diving deep wrecks, especially in current prone areas without two SMBs could spell trouble.
Carrying a second bag is relatively easy. Dive Rite includes a sleeve with all SMBs and lift bags. This sleeve can be mounted on the bottom of a backplate or TransPac, keeping the yellow bag out of the way until needed.

The back lighting circuit is finished and now the production die to mount the LED to the board is being made. The process will take a week and the boards will take a week to run after that. The NiTek X cases are in production. We should have these by the end of next week and start the pressure testing before assembly. Everything is coming together.
For years the Rec wing has been our top selling wing. Divers enjoy the versatile design that allows them to dive both double and single tanks. Same with the Trek wing. Occasionally we hear from divers that the Rec and Trek wings “taco” or wrap around the tank when dived with a single tank.
To remedy this, we’ve created Wing Retainer Hook and Loops that affix to the wing and the harness waist belt. For the past 45 days, our Rec and Trek wings have been shipping with the necessary wing tabs and if you are interested, we can send you the rest of the hardware you’ll need to set up this system. Just send an email to us at firstname.lastname@example.org along with your full address. Shipping is free in the US. Standard shipping rates apply overseas.
A copy of Wing Retainer Hook and Loop instructions are located in our online library at http://www.diverite.com/products/library/productmanuals/
Rebreather divers need to be sure to follow a pre-dive check list before every dive. There are a number of steps that rebreather divers must complete before getting in the water. Some say that multiple checklists are needed: one for initial setup of the unit, one pre dive and another list for checking the rebreather between dives. Dive Rite provides the initial set-up checklist and rebreather instructors use their experience to help new rebreather divers develop the pre dive/between dive checklist. We have posted one instructor’s checklist in our online library.
A checklist may depend on the dive environment. Someone diving from a boat might have a checklist different from someone walking into a spring or lake where there is more time at the surface before starting a dive.
Tom Mount and IANTD have years of experience in rebreather instruction and will soon release a pre dive/between dive check list for rebreather divers. IANTD’s lists will work for a multitude of rebreathers and they will work for the O2ptima.
Dive Rite will begin providing the IANTD checklists with all O2ptima rebreather units and we will send one to current O2ptima rebreather owners. Send us an email with the serial number of your O2ptima head and a physical address that we can mail the lists to.
