 - Zujimavy článok z www.rebreatherworld.com o rozdieloch  Sofnolime vs Spherasorb

I know VRT recommend and qualified the Sentinel with Sofnolime.

While diving my Inspo/vision I was using Spherasorb for quite sometime and never had a problem (even easier to breath than Sofno) same feedback from my 3 fellow divers on inspo. Having lots of spherasorb in stock I decided to also use Sphera with the Sentinel assuming (naively) there will be no diff/problem.

This is NOT true!

Using Spherasorb, the TPM does not react quickly during the pre-breath. With Sofno the graph turn yellow in about 3min and shows a nice pattern. With Sphera count at least 5min to turn yellow and the graph is almost flat. Sphera makes the pre breath a real pain
With Sphera there is much more debris (this is not dust) under the canister under the grid.
Now from a CO2 absorption standpoint I have no way to tell the diff.
