Time to sell a couple of things.
I have an unused older model halcyon 4.5 ft SMB asking $75
An unused OMS Larry Green wing 50lbs lift. Asking $150
Gently loved Medium R&B diving mid weight dry suit under garments. Asking $75
Used suunto pressure gauge, compass with sea quest depth gauge...
If you are feeling lucky and are willing to push your ppo2 then you might be willing to push your NDL. Just skip that pesky 20ft stop, lots of people skip deco and are fine.
****Disclaimer****. I take no responsibility for anyone following this bad advice.
Yea, tec divers don't use computers. Sure.
There is a market full of tec computers.
I would recommend buying a computer if you really want one because there are quite a few places that don't rent them. And a good starter nitrox computer can be had for cheap.
They are running a business not a charity. Making a living in the dive charter business is hard, I have seen too many boats go out of business because they can't cover cost and take home enough money to feed their families.
As a customer some times you gotta take a big bite of a **** sandwich...
