After lab testing the new DSV 300 Micropore, Inc. it was shipped down and I took it diving. The DSV 300 appeared substantially larger than the previous DSV. After installing it on my O2ptima I realized the size wasn’t significant. The hoses attach with locking rings, making assembly easier. The mushroom valves are in the hose inserts rather than in the mouthpiece. The DIVA mounts on the hose side of the locking ring moving it farther from center, which I found to be a good change.
The WOB (work of breathing) has been reduced to fall in the range of other popular units, actually outperforming most. This was accomplished by the changes in the new DSV, the rest of the breathing loop was unchanged in relation to current specifications. The O2ptima has the smallest breathing loop on the market, WOB is the same or better than the larger breathing loops currently on the market. I would say that’s progress.
Charts showing the WOB results of the new 2.5L CL and our former 3L CL and the DSV300 can be found in our online library.
The RX2 LED debuts this week at DEMA. One of the most exciting features on the light is the switching mechanism. We have designed a rotary magnetic switch on the head; the switching is integrated into the board for stability and function. Full and half power modes are at your fingertips, no reaching for a canister switch. This allows multiple mounting options for the diver. The two previous blog entries give some ideas.
This light represents the latest in LED lighting innovation. The RX2 is the product of months of development with US-based companies and all production is made in USA. Our design team engineered the product and feature set – this light is not a “me to” product from a Chinese supplier. The LED boards are the latest in technology and RoHS compliant for European standards. The new polymer boards dissipate head better than conventional boards so we have over 93% efficiency with power consumption to light output. This means we were able to give you more light using the same battery power source as its predecessor the LUX while maintaining the 4 hour burn time at full power.
Dive Rite RX2 LED Slimline Canister Light
Keeping up with line markers is always an issue. Over the years sliding them on a piece of surgical tubing or bungee has been the preferred storage. I see some cave divers doing a bungee on the primary light handmount. I liked the idea, but I had a few storage and deployment problems so I modified it by using a 6-inch piece of 3/16 bungee and stretching it through the adjustment bracket on the Goodman handle. I store the markers on the outside of the handmount with the knot keeping them in place. I find this quick and easy to deploy. I can even keep directional markers on one side and non directional on the other side.
When sidemount diving the light canister sometimes needs alternative mounting solutions. The Nomad has 1-inch D-rings to butt mount canisters on the bottom of the rig, but I haven’t liked wearing my light there because the canister flops around due to play between the quick links and strap. I personally like to have the canister stay in one place, so I’ve continued to wear my light on the waist belt in front of the sidemount bottle. The drawback with this mounting is that you end up with excess light cord that you have to deal with.
Recently, while diving Telford I discovered our Quick Belt Mount (LT6090) is the best solution for butt mounting the canister. I attached it to the 2-inch crotch strap above the accessory D-ring. The light stays firmly in place, I have just the right amount of light cord and if I get into a tight spot I can release the canister.
