Hi Jim... I've included three photos along with this reply. I'm in the process of learning the Barometer before putting together a video to publish. I do anticipate this being done this weekend.
I must say I am very please with the performance of the unit so far.
Here is the link to the first video I did... the unboxing, set-up, etc.
Thanks! I enjoyed seeing the video and the pictures. I hope it gives you years of enjoyment.
Regarding Altimeter vs SLP, since calculating SLP requires knowing the outside air temperature (not the temperature at the device) the DBX2 is almost certainly using Altimeter and just calling it "SEA". One of the previous posters said the manual provides a description of the exact method used but I can't find the DBX2 manual online.
If you want to calculate true SLP this site does it:
https://www.starpath.com/barometers/baro_cal.phpThe above site will also provide a list of nearby weather stations with SLP data.
When checking pressure I like to use this site, which shows hourly Altimeter and SLP (if it's available) :
https://w1.weather.gov/obhistory/KZZV.html (just replace KZZV with your local station... it is case sensitive)
I love barometers and have a collection of old aneroid ones but my precious is a working Fortin mercury barometer. Not as accurate or precise as yours but when it tells me the station pressure is 27.59 in/Hg, I'm really looking at a 27.59" column of mercury.
