@zai.gezundt I suggest you buy a new Oring (Casio Part SGW400). 1) Clean the Oring groove with a Qtip with isopropyl alcohol. 2) Carefully lubricate Oring with silicon grease. 3) install Oring back making sure the "square" part fits in the corresponding part of the groove. 4. Close back the...

@zai.gezundt No, I've never tried that experiment with the Citizen HyperAqualand. To me, the real test has always been that the beeper must work with the case back closed. From your first picture (I don't have an open Edy in front of me) I reckon that the two "reed" shaped contacts are...

zai.gezund, Did you reinstall the sticker after replacing the battery? In servicing Cressi Edys I have always reinstalled the sticker (even using a drop of silicon glue when necessary) so I don't know if not doing so could prevent the piezoelectric crystal from beeping. However, I have done...

Zai.gezundt, I noticed in your picture that the battery does NOT have the original self glued sticker with specific instructions on how to reset the computer after replacing the battery. That prompts the question: did you reset it? You are supposed to momentarily short circuit two bronze...

If the spring makes contact at the red circle, that point and the spring itself (does it come off?) would be my primary targets during the cleaning operation. But then I don't have a clue what could have generated the "pointy dark spot". The faint sound you can hear with the cover removed is...

Donnad, Firstly, your Aeris Manta only stores the last 24 dives. The procedure to access the LOG is referenced in pages 59 and 60 of the User Manual. While in NORM-SURF-MAIN screen, pressing A button less than 2 sec. gives access to PLAN MODE LEAD-IN screen. Pressing again A button for less...

Dmaziuk has a point in suggesting you should verify the battery voltage. However, be aware that the Cressi Edy takes a CR2032, which is a 3V lithium battery. Secondly, "the white circle glued" is precisely the piezoelectric crystal that beeps when an electric voltage is applied to its terminals...

We disagree with Tridacna. The brand is very relevant, insofar as performance is concerned. Sony or Panasonic (if you can get the ones made in Japan) are probably your best quality option. Renata (Swiss-made) and Maxell (Japan made) would be my second choice, followed by Varta (german made). The...

Griffon, I disagree. The actual size of the Mosquito and D3 dive computers is 1.2mmx21mm. A guy sells them on eBay.

I know this is an old thread, but I want to clarify "Arturo's" status as a scubaboard member. "Arturo" was my old Scubaboard member's name when I was living in Venezuela. In 2014 I moved definitively to Fort Lauderdale, FL and ceased posting as Arturo. In 2015 I started "Divewatchdoctor", a...

CuriousRambler, If you send us your Aladin Tec2g, we could waterproof it to 160 feet and check your computer depth reading vs. our Bergeon calibrated pressure gage (check our avatar) every 20 feet and report the results back to you. It would cost you $ 25 plus return shipping. We DO waterproof...

Sorry to hear that.

Eduardo, I am familiar with your Aqualand model. As a last-ditch effort it won't hurt to install a fresh battery, follow again the complete reset procedure (i.e unscrew and pull fully out the crown, press the three buttons simultaneously for a couple of seconds, wait to hear two beeps and...

Shurite7 is right about the pool chlorine being harsh on gear. In the case of dive computers and dive watches with pressure sensors (like the Aqualand, HyperAqualand, Casio DEP 600, etc) the chlorine degrades the properties of the insulating gel in the pressure port.

Eduardo, Depending on the model (Citizen has sold at least 10 different Aqualand models), flashing "ER" on the display of an Aqualand could mean two things: a) You have to replace the battery or b) Indeed, a pressure sensor error has been detected by the software and your watch has to go the...

More than a hit on the way down (an particularly for the button popped halfway out), I tend to believe that some kind of marine life noticed the computer on its way down or sitting on the floor and gave it a good bite or two to check if was something edible. Of course, this is pure speculation...

HalcyonDaze, I don't know either what Error code "E20" means (full disclosure, an Uwatec Prime has been my trustworthy backup computer for the last 12 years). Having said that, I see two scenarios for your Aladin Prime: 1. After sitting for I don't know how much time at 30 feet of water your...

Joe Friday, certainly using a thin (lower viscosity) oil will reduce bubble retention. We regularly use Johnson's baby oil which is cheap and you can get in any drug store. What oil do you use? Transformer oil by any chance?

Aklinz, I can't guarantee they both use the same Oring. What I can tell you is that the Savant "O ring" is rectangular in shape, with a circular cross-section.

Joe Friday, We are aware of your method of getting rid of the bubbles. Usually, it works, but is quite messy and requires a lot of oil (95% of which will be recovered, I grant that). We use a different method. A point worth mentioning about the air bubbles: unless you leave the inside of the...
