Question about Suunto Cobra Integrated Computer

# Depth and time not correct

Working with some students in a pool at 10 feet fresh water my suunto cobra displayed 65 feet and had me in violation of non-deco diving. Out of the pool, it said i was at 55 feet. The next week it did not display any depth or time, only air pressure.

Do you live somewhere significantly above sea level?

If not, check your personal altitude setting. It's explained on pages 20 and 23 of the manual.

### My pool is 16feet wide by 32 long 10 feet deep what is the square footage

What you looking to know?

Square feet suggests a flat area, like the floor plan of the pool, which would be 16 x 32 = 512 square feet. Like you'd measure walls for tiles or paper etc.

As you've given 3 dimensions, sounds like your after the cubic capacity/volume of the pool, in which case your looking at cubic feet (same as flat area above, but with the added depth to go from flat 2d, to 3d (2 vs 3 dimensions)), which would be 16 x 32 x 10 = 5,120 cubic feet.

### I have a 22 x 52 intex pool and need to know how much salt to add for the first time

the equipment should specify the parts per million of salt required, just google your make and model for information, then take the volume of water(22 x 52 x average depth) and multiply by the required salt concentration. then divide by the bag weight to get the number of bags required. Get some spare bags, but start with a few less than calculated, this enables fine tuning as you test the water a few times

### Suunto Cobra Computer Console, battery replacement

Hey scuba2man, I have the same problem. Did you ever work out what was going on? My console didn't register any depth for first couple of dives (I had to turn it on every 5 mins to check air). Next couple of dives it told me I was between 98 and 103 metres deep (whatever that is in feet). I was at a maximum depth of 22m!!
I will let you know if I find solution. If not then I'll just get a new one!!!

### Pressure gauge problem with Suunto Cobra 2

Salva,

The error in pressure is actually a "feature" of Suunto computers. Suunto is probably one of the most conservative brands out there, and many experienced divers tend to stay away from them for that very reason.

The manual actually calls out this "feature" on page 27.

The remaining air time calculation includes a 35 bar/500 psi safety reserve. This means
that when the instrument shows the air time to be zero, there is still about 35 bar/500 psi
of pressure left in your cylinder, depending on your air consumption rate.

### Lowrance x96 does not function after 20 feet depth

Your transducer needs to be adjusted so the return signal can be picked up. Some of these have to be super tuned to receive the signal. Also the transducer may be moving ever so slightly when the boat is traveling at speed. You may have some water turbulence interference all contibute to signal return.
