Tribolube 71 Lubricant

By

I recently did the annual service on several O2ptima units and I was amazed at the amount of oxygen grease being used. Grease is not the best lubricant for all applications. It is designed for high pressure use, not the ambient pressure seals on a rebreather breathing loop. The use of oxygen grease has gotten way out of hand, almost as much as the use of Viton o-rings.

For the best performance on your O2ptima use silicone lubricants on all the ambient pressure seals on the breathing loop. It will go together easier and the silicone will not attract the dirt and grit like the oxygen compatible grease. We carry the Tribolube 71 and use it when servicing the O2ptima as well as regulators.

NiTek X Beta Update

By

Test diving the NiTek X in cold weather brought a few points to my attention. If it is extremely cold the computer may not come on until the weather warms up. I discovered this after leaving my X in the back of my truck when it got down to 18 degrees. This is a function of the battery quality so we are changing to Duracell batteries since they actually publish their operating temperature range.  Some people have noticed the battery cap  o-ring may be slightly exposed, don’t worry it is sealed. The next run of NiTek X parts will include replacement battery caps for all the beta units. The new cap will be black like the Fischer cap side with a knurled grip for easy access with no tools.  Be sure to register your NiTek X online and we’ll let you know about any available updates.

O2ptima Manual 4.0

By

The latest O2ptima manual is out with more information about the features of the O2ptima. It’s available in our library or listed under downloads on the O2ptima product page. I have had a couple of instructors review it and found it to be more informative then the earlier one. We have a number of updates and accessories slated to come out this year on the O2ptima like the new stand we just released. I will keep you posted as these things are available.

 

On a side note the NiTek X can be quickly added to the O2ptima. We need to drill and tap the head to insert the cable. I have been flying my unit with both handsets stored away in pockets attached to the bottom of the CL, using the DIVA in PPO2 mode and 4th cell plugged into the X. If you want to try this just send me your CL and I can have the pockets sewn in place. I can’t give you the pockets but I can give you the time to sew them in place.

H10 Reflector and Goodman Handle Upgrade

By

The new HID 1000 adjustable reflector assembly has some improvements over the old H10 reflector. The HID 1000 reflector is recessed into the shroud so there is less backscatter and a better pin-point focus. The new shroud protects the reflector from damage as well. They don’t survive sitting your cylinders on it.

The HID 1000 reflector comes standard with the metal Goodman handle on it with the big pad to rest on the back of your hand.  If you have the H10 light the new reflector from the H1000 will fit and you will feel and notice the difference. I wrote this because I have been asked in the field about upgrading the reflector. You can do an upgrade directly with us at the factor and it will only be $59 if you reference my blog. Otherwise, the retail is $99.
