Dude....I gotta tell ya I am not really impressed with the Hammerhead. Why wouldn't Kevin include NDL on the units....kinda lame if you ask me.
I agree with kevin on this one (with one exception)...
The HH was designed as a full trimix decompression computer and a majority of the owners are using it as such.. In these conditions guessing the NDLs are just shot in the dark(some computers do a better job than others).. No computer gets it right so why put such useless information.. Its not uncommon to just exceed a NDL and immediately have 10 minutes of deco.. obviously the guess isn't that good..
If you are using straight air or heliox the NDLs can be readily predicted, adding it would probably make a few people happy, but most of us don't care since our dives are planned out ahead of time, are decompression dives, are trimix dives or also have another computer like the explorer added to the loop..
The Key things with the HH is the Trimix integration, dead on PO2 control, and reliability. kevin always looks for suggestions on improving the unit, and listens to what people want.. Join the Yahoo group and see what people request.. There have only been a few who have asked about the NDLs and those really aren't doing the dives that make the unit shine..
Even without a NDL display it still is considerably more functional than the standard controller.
The deco alg in the HH is superior to the VR3, is truely customizable.. I can ajdust the gradients to give me a curve similiar to a bubble model like RGBM in the Explorer and then change the GF mid dive to get a little more agressive on the shallow stops to give ending run times closer to RGBM.
