Thread Status: Hello
, There was no answer in this thread for more than 60 days.
It can take a long time to get an up-to-date response or contact with relevant users.

don't know about the d3 but the mosquito is far from impressive. i have the 3rd replacement at the moment, my girlfriend the 4th. suunto service is questionable, i sent them some emails asking for some advice and never got a reply. of all the guys i know who use a mosquito about 70% have problems.
the stinger seems a lot more reliable from what i hear.
unfortunately there is no real alternative, yet. hopefully eric's watch will change that.

I think those computers are pretty much identical hardware wise. Propably some minor differences in memory and of course software...Just a guess.
If you only freedive, then I would go with d3. All that scuba stuff in the mosquito will just make using it more complicated. But if you also scuba, then it might be worth considering.
The stinger is so ridiculously priced that personally I'd never consider it.
Why not go for the F1? (www.liquivision.ca) Be adventurous and test it for the rest of us
That's what I'm hoping will be my next computer...Just need to save some money and of course have it generally available...

That's what I'm hoping will be my next computer...Just need to save some money and of course have it generally available...The pre-order F1's will be shipping on August 21. Shortly after that (perhaps Sept 1st), the F1 will be widely available and in-stock for immediate order.
The 'production' F1 blows away the 'prototype F1' (which Mandy used for her 50m record). The production F1 has a beautiful curved color-anodized aluminum casing, scratch-proof mineral glass, an AWESOME strap (best you've ever used), and it has a TWO tone alarm (like a siren), in addition to the yellow/black organic LED display.
The basic F1 comes with the wrist computer, the button attachment, and the charger. If you purchase the PC interface, then you can upgrade the software on your F1 (new software releases will be posted monthly on the F1 site for immediate and free download). You can request new features on the F1 forum.
The F1 is expensive, but realistically considering how much it costs us to make it, it is extremely cheap. If this same computer were being manufactured by a big company who needed a bigger profit margin, it would cost as much as a car.
In the meantime (before the F1 is available), the Suunto Stinger is really the only reliable computer available for freediving.

Hi Eric - saw this on your site :
"and a prompt for minimum surface interval reached (for spearfishing)."
Can you give me some more info on how this is determined ?
ie is it based on your dive session ? So it knows that you have made 26 dives in the last 2 hours so might need to add some time to the top time ? Or does it work out the last dive time and then calculate the safe interval ?
Cheers

In terms of minimum surface interval, you have two choices:
- Pre-program your minimum surface interval based on your planned dive pattern (i.e. check the tables and choose 3 minute interval, etc.)
- Allow the F1 do freediving decompression calculations
In all likelihood the freediving decompression calculations will not be available in the 1st revision of the software; they will be included in a subsequent release, which you can easily load onto your F1 with the PC interface.

The F1 has 2MB (2048K) of flash memory, which is utterly enormous when compared to any 'normal' computer.
The number of dives you can log depends on what data you save, and how often you sample/save it. If you want salinity, temperature, depth, and velocity, all recorded at 4 samples per second, then you will be able to record a certain number of dives. If you only have depth, recorded at 1 sample per second, then you can record way more dives, and so on.
If you recorded data similarly to a D3, i.e., depth at 1 sample per second at 8-bit precision (same as D3), then you could record 2,000,000 seconds of dive data, or 555 hours.
If each dive lasted 1.5 minutes, then this would equal about 22,000 dives.

Jon,
Scuba deco software will be available, but it will not be written by us. Once the home development kit is available, you will be able to download software from 'open-source' websites.
Links to such open-source websites will be on the Liquivision site. You follow those links, and then you can select whose scuba software you want to download. There are many tech divers who are also competent programmers, and they should have no problem writing scuba software for any gas configuration.
The reasons for the open-source nature of the scuba software are:
1. No liability for us
2. The people currently collaborating on the F1 are freedivers, not scuba divers, so we doubt we could write effective software for tech scuba
The F1 does have a scuba gauge mode. The scuba gauge mode has difference from freediving mode, for example it displays a longer dive time, and displays velocity in different units (example fpm rather than m/s). You can also combine the event mode with the scuba gauge mode, which will allow you to program a pre-planned dive plan (i.e. 5 minutes at 30m, 10min at 20m, 2 min stop at 5m, etc.) and the F1 software will cue you as to what the next checkpoint is and how much longer you have at your current checkpoint and so on. However, this mode is more like a DIR mode where the computer isn't doing deco calculations, it is just acting like a reminder for a pre-planned dive.

Average depth is one of the options in scuba mode.
Programming full-custom software yourself would require the home development kit and a windows compatible PC. Programming would be in 'C' only.
You can also 'purchase' custom software from us, if you don't have the inclination to write it yourself. In the case of simple additions, in some cases it would be cheaper to have us do it, since the development kit may be a bit pricey (due to 3rd party licenses we have to buy for each kit sold). Or, you could ask a friend who has the development kit to write you extra software features for free.

Hi all,
Hi Eric,
I am one of the lucky guys to have placed a pre-order for the F1 (actually, it is even better as it is my wife who ordered did for me as a birthday present :inlove ). Now I am just wondering if there will be any differences between the pre-ordered units and the ones available afterwards. Not that I am worried, but just curious...
Anyway, I just can't wait starting playing with it
Keep up the good work guys !

Jacques,
There is one small difference between the pre-order F1 and the production F1.
The pre-order F1 will have slightly simpler software, but this can be easily upgraded later by either sending us your F1 or by using the PC interface.
The reason the pre-order F1's have simpler software is that the software on the F1 is so complicated that there is not enough time to program all of the advanced features by the time the pre-order computers ship.

A bit back to the original question (D3 or Mosquito):
I'm using D3 for about 1.5 year. I used (and using) it a lot, because I use it for pool traiing also (I'm lazy and it shows the surface time, and it is good for the series [DYF, DNF]). Fortunately, I haven't had any problems with it.
Of course I'm also curious about the F1, the specification sounds very good, the "brick" design is a bit strange, but it's not a big problem - you have to get used to it, I think.
