Signal drop out is not a problem on a AI computer unless it fails to resync within a reasonable amount of time. What is to be considered reasonable is fast enough to insure you get another pressure reading long before the possibility of running out of gas. In this respect Oceanic computers are excellent. I have found them highly resistant to high power strobe interference and at worst raising your computer towards the transmitter will reestablish sync nearly instantly. In extreme cases you may have to consider which port to use on your regulator for the transmitter and computer to be closer. All AI wireless computers exhibit some signal loss from time to time but with good batteries and well thought out transmitter installation very few signal losses should be considered failures. Not having a pressure reading is of no more importance than the time you spend not looking at your SPG if using Brass & Glass gauges. You as a skilled diver should have an idea of how critical your remaining gas supply is without looking at your gauge or computer. It is a skill taught during your open water training and is a skill that should be practiced and further developed as you gain experience diving.
