I conducted a lot of research before purchasing a Cootwo. ......
Hi,
Thank you for purchasing cootwo and for your report.
Unfortunately you report includes several incorrect and misleading statements. Please see below.
...... After purchasing the analyzer I learned that if the battery dies you might not be able to recharge it at all. ......
Li-Ion batteries should be kept properly charged. IF a Li-Ion battery is not properly maintained it MIGHT die off - but that is not always the case. We recommend customers to recharge the battery once a quarter (it takes ~1 hour or so).
IF you let the battery die, you can replace it yourself as it is a standard AAA Li-Ion rechargeable battery (it costs a couple of dollars online)
.....So if your battery dies, you’ll need to re-calibrate the sensor...
FALSE.
The digital calibration is stored in a flash memory.
If you remove power for a long period of time the CO sensor (it is a chemical sensor) drifts off (it appears as it lost its calibration). Once you re-apply power (after power was removed for a long period of time) you will need to wait for several minutes (we recommend at least 1 hour) before using cootwo as the CO sensor needs to recover from the drift status (it is a chemical sensor)
...... I also read online that if you accidentally drop the device the CO sensor easily pops out ....
FALSE.
This was an issue that happened only on few early models and it was corrected 3 years ago.
...... the CO sensor easily pops out and therefore you’ll have to re-calibrate. ....
FALSE.
There is no need to recalibrate the CO sensor if you remove it for a short time and then re-install it. See above.
...... I read on ScubaBoard that if there is a firmware update you have to mail the analyzer back to the company for the update. You can’t do it yourself. .....
Last firmware update was done in May 2017.
If necessary, we update the firmware for free as part of our yearly CO calibration service
...... When I first turned the unit on there was a bright vertical line on the left-hand side of the screen like a broken Gameboy. I’m guessing the screen just wasn’t lined up in the unit correctly......
Are you saying that the display is defective?
If so, please provide proof of purchase and we will replace the unit as part of our 12 months warranty.
...... When pressing the buttons I thought there would have been a quicker response. Sometimes when clicking on the single button to go through the menu options I would have to press the button several times to scroll through. .....
As explained in the manual, HOLD = 2 seconds, PRESS = 1 second.
Use the app if you do not want to press buttons.
...... I thought for $50 for a LP hose adapter and a carrying case that the case would have been waterproof and airtight. It’s certainly not..
As clearly indicated on our online store
HERE, the carrying case is not waterproof.
...... I’m sure I’ll sound picky by saying this, but the Cootwo has a triangle shape when looking down at it, not rectangular, but the padding on the case is rectangular so the unit doesn’t fit flat in the case. Also, if you try to set it flat in the case, the molding isn’t cut right for it. .....
We never received a complain from users concerned how cootwo is sitting inside its carrying case nor we ever received complains that cootwo got damaged while being carried around in its carrying case. cootwo itself said that everything was looking good and comfy.
...... I would like to think the grease is oxygen compatible since I was planning on using this unit with 50% nitrox and oxygen, but if it’s not, I certainly don’t want it touching my DIN valves. Just a clarification from the company would be nice.
Yes, the grease used on the inside of the adapter must be Oxygen compatible.
...... For $350 you don’t receive a cheaply printed manual or even a disc. You’ll receive a business card with a link to the manual, tinyurl.com/cootwo-manual.
