Some DiveOps are making them required for dives like the Grove, other deep wrecks.
And if you don't have one who do you buy/rent from. It sounds like they are trying to make a dollar to me. Besides the Grove isn't considered a deep wreck by wreck diving standards.
Like anything else where the is $$ there will be those who seek to sell. Understand what the tool will do for you and buy it when you need it.
I dive with a computer and have a backup on every dive. If it breaks I will still get to the surface safely.
I like using a analog depth gauge for accents. It is way easier for me to watch the hand sweep and count onethousandone, onethousandtwo...
