Palm D Oxygen Analyzer

Passed my Nitrox certification and brought it with me to the instructor when was doing final exercises. I was very glad to find that it's accurate and work smoothly. The best product in this price range. Highly recommend.

Opened the package yesterday upon arrival and the unit would not power on. No owners manual included, but was able to track down the manufacturer and find the correct manual. Batteries are supposed to included, tested and good for 13,000 hours. Followed the instructions for case disassembly and immediately observed the battery contacts were not close to touching either of the batteries. Pinched them together and reinstalled the batteries and the unit is now working. Also, might be my mistake, but I thought from the product description that this unit was also supposed to come with a blue disfuser attachment and a bag, neither of which were included.

Small, accurate, easy to use and a great value

Good value for recreational dive use - price vs accuracy

The O2 sensor doesn't last long at all.% Readings all over the placeNot good value.

I have used this analyzer many times and it works great. But it should ship with the optional tip for bcd. Or at least offer it.I have tried to locate this tip separately but no one is stocking it

Easy to use, cost effective and accurate

Ordered the O2 analyzer for my husband for Christmas. He opened it today and the analyzer won't calibrate. No manual was included.
