Duck Weed

SlowDiver

Received my HammerHead Rebreather the first part of October and started my training with Tom Mount in Miami. I had met Jakup of Golem Grear in Feb. at Jackson Blue to check out the smaller scrubber and decided it would suit my type of diving, which is a quick cave dive and go home. By using the standard canister with the smaller scrubber I had to have a larger spacer inserted in the bottom of the canister. This caused and unexpected plus that I had not counted on. By having a larger air pocked at the bottom of the canister I needed no weights added to the counter lungs to keep me horizontal with great trim.
Training with Tom is great and at my slow pace. Trained on some small reefs off the coast of Miami and the Spiegel Grove. Was schedule to dive the Capt. Dan and Hydro Atlanta but the weather said no. Will do at a later date.
At Orange Grove doing some practice dill flush and gear removal when my HUD started failing so took the unit off underwater. Found the problem with the connector not being screwed tightly down so water had entered the plug. Went to the surgace and dried the plug and put the unit back on. Now Orange Grove for those who have not been there is full of Duck Weed which is a small green plant. By taking the mouthpiece out and working on the HUD at the surface I found out later was a bad mistake. Anyway, put the unit back on and descended back down to about 20 feet when I noticed the readouts on my computed was getting blurry. Knew something was wrong and switch to OC and thumbed the dive. Told my buddy it was time to get out and go to Bill Rennaker's at Cave Excursions who was holding his annual REAC.
Next morning I woke up with a bad headache and when I cleaned the unit I found the problem. Inside the BOV both one-way valves had that Duck Weed stuck everywhere and could no longer function correctly. Lession I won't forget.

Are you sure its not just your aging eyes? I always find the HH display blurry and hard to read at the depth were ambient light is low but not low enough to need a torch to see. Kind of like twilight. I have put a guage magnifier in my mask and it does help me.

I guess more dives will determine if it was the duck weed or your eyes and the small display numbers.
