There are dire problems in making a cheap diving computer.
One problem lies in the labor. In order to make a $200 dive computer, the labor involved must be only a matter of minutes, in order to make it financially feasible. After all, for a $200 computer, the dealer will take a $30 cut (at least), there will be $7-$10 in credit card fees.
In every venture I have made so far, selling the product for 3 times the manufacturing cost (including labor), still barely breaks you even. You really need to sell something for 4 times your own cost, which is why the F1 is probably not viable, as it is being sold for only 1.5 times our cost.
$200
- $30 dealer cost
- $10 credit card fees
= $160 gross income
divided by 4
= $40 our cost for labor + parts
For a hand made product, labour would be a minimum of 2 hours, for at least $20 per hour, giving $40. This leaves $0 left to buy parts with.
So, the only way to do it would be to have machine automated assembly, with no human labor involved, or, alternatively, increase the price to $300.
For $300:
dealer cut $45
credit card fees $12
= $243
divided by 4
= $60.75
2 hours labor @ $20/hr
= $40
left over = $20.75
So the parts would need to cost $20.75. This is problematic since a pressure sensor alone costs at least $12, the circuit would cost at least $3 (in giant quantities), the battery would cost at least $7, and even without other circuit components or casing or strap we are already over the limit.
So, I would say the cheapest I could ever make a computer would be $450, unless it was assembled by an automated factory, which costs hundreds of thousands of dollars to set up and offers great risks.
