Dove this comp 8 times. Still getting used to it. Do not use trimix.
Two issues, One surface temp indicator is 15 to 20 higher than actual
temp.
More importantly, My second comp showed a max depth of 172 and the Cochran
showed 177. Big dif.
Has anyone else exp issues like this.
I am working with Cochran on this, but wanted imput
Not jumbing up and down with this comp.

I have 16 years experience with Cochran computers, and was one of the principal beta testers for the EMC20H -- we have years of experience with them.
1. Cochrans measure salinity of water and are not set in a "fixed" pressure transducer that can only measure meters or feet. As such your Cochran is to be considered the baseline for all your measurements. All other computers will be "off" Swiss units measure based on fresh water, Japanese / US units measure based on salt water.
2. It can take upwards of 10 minutes for the temperature to stabilize in water. Don't sweat it. If you put it in 55f water and it shows 65f after 10 min send it back for calibration. Surface temp is usually within 5f of what a decent thermometer shows, though I dont care because I use it to check water temp not air temp.
3. It will take you about 10 decompression dives to get used to the powerful features of the EMC20. It will also take you a good conversation with an avid user to really dial it in.
4. I use Cochran EMC20Hs on ALL my dives. OC, CCR, deco, no-stop. I probably own about 8 of them all together.
5. You have probably the most sophisticated dive computer on the market today.
6. Analyst software can be difficult to use at first. Then you will learn it's idiosyncracies and learn to love it.
