According to the manual, there is a variable ascent rate for the Luna based on your depth. I don't know about anyone else but I find it to be a bit touchy. I understand the concept and need for a slow ascent rate but it alarms when you reach 110% of their "ideal value" for an ascent rate. This creates a lot of alarms, especially when working with students. According to their chart, here are the "ideal" ascent rates:
All in feet/feet per minute
Feet - Ideal Rate
<20 23
<40 26
<60 29
<75 33
<88 36
<101 43
<115 49
<128 56
<144 59
<164 62
>164 66
There is no adjustment for this alarm, you cannot do anything about it. So when you are coming up at a slow 30fpm from a shallow 60' reef dive, you are alarming like crazy.
Anyone else have this issue on ascent with the Luna?
