I love mine. Its a large size, has been to 180ft with me, Night diving, and survived air travel. The switching from salt to fresh is a pain and Metric to Imperial but otherwise its a great computer.
The batteries last a loooong time.
heres my review from epinions.com:
Pros: Small size, Big display, Program adjustability, big log, long battery life
Cons: backlight is short, low batt issues (locks out)
The Bottom Line:
On par with the best, a better unit is the Gallielo Terra. Its a good buy, rock solid, and well built and can be found online.
tartullian's Full Review: Tusa DC Sapience "Nitrox" Dive Computer
To understand a Dive comp purchase it is good to understand the diver making the review. Most of my diving is in the evenings after work and roughly in the recreational limits. I dive both fresh and salt water, my average dive is 80ft, average water temp is about 38F, and I dive a dry suit. I have used this Comp in tropical conditions as well.
Overall I am very happy with the Tusa, The software is adjustable to suit the diver, it came with a scratch protector, the band is of good quality, the overall size is small but the buttons remain easy to operate. The battery is long lasting and diver removable. This is key, I dive in the summers several time a week in the winters about once a month and the current battery has lasted two years.
I really enjoy the ability to adjust the safety factor and the option to turn on and off the vibrate function. Vibrate is nice if you are diving in a loud environment (by a dam or in a heavily traveled channel or even with other divers who's comps are always beeping) or with a thick hood.
I should note the switch from Imperial to metric is a bit of a pain but it is not a common change. Some of my buddies dive in meters, I prefer feet.
The one thing I wish this comp allowed for was continuous back-light. In sunny conditions you don't need it but in lakes in the evening its a pain to keep turning on the back-light.
I should also mention that in a low batt situation it will not enter dive mode. I'm not sure this is acceptable. A better response is to just do depth gauge. Mine beeped for a couple dives (on a boat... how would I change the battery?) then it just would not enter dive mode. I would much prefer if it went to gauge mode or turned off the display after surfacing from the last dive on the first sign of a low battery instead of me jumping into the water to find out I have no functions on the comp... no depth.. no nothing... but on first glance it appeard to be working.
the moral of the story? Keep the batteries up and you have an excellent comp.
