What recreational dive computer is this. It's not one that I have or have ever seen. Any that I've ever seen would lock you out only if you didn't do the decompression before getting out of the water.
Sherwood Wisdom 2's operator manual's page 4:
"it should not be utilized for any competiitive, or repetitive square wave or decompression diving, as it is intended solely for recreational use and no decompression multilevel diving."
page 84:
"When a Decompression Stop Depth greater than 70 feet (21 meters) is required, the WISDOM 2 enters Permanent Violation Mode and reverts to Violation Gauge Mode operation for the remainder of that dive and subsequent dives made within a 24 hour period. Once in the Violation Gauge Mode, the WISDOM 2 operates with limited functions without any nitrogen or oxygen monitoring or calculating functions."
So, you are partially right and I'm partially right (I should have read the manual in its entirety). If a diver were to go exceed NDL then the computer will go into decompression mode and if the diver were to go follow the computer's decompression profile then it's OK. BUT if the deco stop depth is greater than 70-ft then the computer will give you a deco profile to follow but then it will lock you out for 24-hrs.
On the Aeris Elite T3, it's similar except that the decompression stop depth is 60-ft or greater (10-ft shallower than the Wisdom 2) as shown on the operator manual's page 98.
