Loop temperature ranges

Sue · 13th May 2006, 22:12

A few dives after my training I'm now more relaxed to browse through the display's menus during bottom time and I'm trying to understand the loop temperature's variation into the dive.

Today, 10' after I entered the water I had
water temp: 16C
loop temp: 26C

50 minutes later I had
water temp 15,9C
loop temp 21C

What values do you usually get in your dives? What's the maximum variation you have achieved in a dive?

Thanks

Sue

Looks like you're not getting much traction. For me I tend to be about 7 degrees F above water temperature in the 48-50 deg F water I normally dive. Good luck!

i normally get 2-3 deg above water temp in 6-11 deg water

Hi; I dive in the South China Sea in balmy 26-28 degC conditions. My loop temp usually remains 1-2 degC above ambient.

Hi Sue,

Lots of factors at play that will effect the loop temp such as; depth, water temp, work rate, tidal volume, ADV or O2 being added etc

On a dive deeper than 80m with a reasonable current, I can get a difference of 10 deg C. I have had the loop read cooler than the water when doing skills (open loop)
