NiTek X Update

By

 

We have listened to requests for more logbook memory and compatible cabling for 4th cell CCR integration. All these things are a go, but delayed the production beta units. We had to give up our slot at the PCB production house to address the new hardware features. As soon as we can get back on the schedule at the PCB house we are days away from production beta units.

O2ptima Rebreather Counterlung Placement

By

Work of breathing varies with CCR models. The O2ptima has the shortest breathing loop on the market and because of this we can use smaller hoses. However, with this feature comes more attention to detail. The counterlung must be mounted in the right place to take advantage of the smaller hoses. The T-piece connections and ADV must be located high on the chest just below the shoulder. If you move them any lower on the chest then WOB will increase. If you feel the WOB is too great then adjust the CL higher with the attachment straps. This is critical. Once you get the CL positioned correctly, you will find that you can breathe vertically, horizontally or upside down without a problem.

NiTek X Update

By

The production beta units should be ready next week. The boards are going to the production house over the weekend for programming. We will also be getting ten beta units for final testing.

We are increasing logbook capacity by adding another chip for more memory storage. We should double if not triple the 6.2 hours in the design. The 6.2 hours was worst-case scenario based on diver settings, profile sampling rate, flags, OC/CC mode and gas switches. If you’re traveling and can’t download until you get home, set the sampling rate at 30-second rate for more storage capacity.

We are using an industry-standard transducer rated to 150m. If you take it deeper than that it will not lock out, but there is no guarantee as to the accuracy or the integrity of the pressure transducer.
