I have used a couple of hose end computers and then switched out to the hose less. I did this not because it was hose less as much, but it was always where I could see it and it tracked more than one gas or tank. You still need to have pressure gauges on all your tanks. The first one was an Eris Epic. A very good sport diving computer with a small footprint that does multiple tanks.gas (3), allowing a gas switch on the dive. It always worked without a hitch, just don’t push your bottom times. This can be had for about $500.00, less if used.
I have a Uwatec Galileo Sol and am very happy with it too. Don’t expect to use very many computers like the Epic for backup if you get into tech. They don’t do well with deep stop or post deco. I would steer clear of Suunto, since on many occasions when I have been diving with people who had them,(almost shoulder to shoulder) have found them locked out or barking to go to the boat because they had not adjusted for their dive plan. Many of my computers had/have an adjustable conservation factor, but Suunto is very tight.
