tec computer for occasional tec dive recommendations?

[Centrals]

1. Invest on a deco soft ware eg. Deco Planner.
2. Buy another cheap computer with gauge mode. You need two bottom timers for any tec dive.

There is getting less and less to say about computers. I use a shearwater so consider this bias.
you need one that you can navigate the menu with out a manual.
you need one you can read now and perhaps in the future. (glasses wearers)
you need more than nitrox capability if you are even considering going to progress to trimix if not you have lost nothing
you need a power source that is common to any store.
you need large control buttons to be able to work with gloves.
you need one that you can download software updates to remove flaws.


you can buy one now and then another later and it will cost more than getting the right one for you to start with.

im not pushing shearwaters I am pushing the needed qualities and capabilities that are available in more than just shearwater.
