| Re: First Two dives on the Hammer Head
About the HUD. I had the same problem no green no yellow, only red. I tested with the HH of a friend of mine. It was the HUD and not the connection. The unit of my friend is now at JM for a "nickel plated to SS" upgrade, so I sent my HUD with his handsets to JM. I'm now using his HUD and it works great. We will see what Kevin says about the HUD.
The handsets are rather heavy so you have to pull the straps really tight. I keep the secondary clipped off to a d-ring. The cable for the primary is twisted once around my arm. That keeps it better in place.
Mark, if you still have the first nickel plated version, talk to Kevin about an upgrade to the latest version. They are more robust and the SS bezel is far better than the nickel plated one.
Calibration - calibrate at home before the dive trip. I don't calibrate very often (ones per month or so and before a longer trip), but I check the MV cell readings in air and at 6 meters with O2.
Battery problem. I'm using contact cleaner spray because I have not found that conductive grease and that also helps. I had a problem with a battery at depth. I checked the battery with a battery tester and it was still good. I cleaned the battery compartment and the cap threads and continued using the same battery. No problem.
