Comments about Sherwood CG4105 Wisdom Dive Computer with Compass:

I tried to use this model on over 100 dives. When I would dive at altitude it would go bonkers as described by others. It would think I was underwater after I surfaced and think I was still diving. While diving it had the depth wrong. Finally, it would lock up and I would lose my dive history. Twice it just locked up without going thru the other steps. I sent it back 3 times and the last time I just put the new one away. I pulled it out 2 years later while my replacement computer was in the shop, dove with it at sea level and it didn't register air pressure and sometimes the depth readings were okay and sometimes they were off. A number or people looked at it and couldn't find anything that could be causing the problem. Every time I used it after it died the first time, I had to dive with a backup computer just in case (and I am glad I did).

Too bad. I liked the design, the size of the digits, the air integration, the quick disconnect and much more.

Maybe they have gotten better in the last 2 years. I tried to use it every time it wasn't in the shop from the time it was introduced until I finally bought another air integrated computer the last time it was in the shop. I dove with three of them back to back with no luck (about 2 years?) and then shelved the last one. Maybe they just don't work well with altitude diving and if you only dive with them at sea level you will be ok (doesn't explain the last problem at sea level).

After one year and 100 dives I realy like the unit. Easy to use and see. I would question its reliabilty as the main button just fell out. Its in for warranty work but should not have happen. My dive partner had two units flood and my first instructor went through several units. I will not buy another even though I like the unit. Next one will be a none air intrigrated puck. Don't realy need air intregrated for none technical dives.

I did have to return one of these computers because it malfunctioned during a dive 100 feet. Leisure pro did replace it, and I have had no further complications. I hope it remains reliable.

My Wisdom is awesome. It has every function you could ever ask for and is Nitrox compatible. The audible alarms definitely let me know my limits. Overall, no complaints whatsoever. The only regret I have is not purchasing one earlier.

I purchased two of these dive computers. One for me and one for my wife. On the second dive mine went haywire. Alarms went off as the computer said I was over 100 feet deep. I thought to myself wow what a cool divemaster he took us on a deep dive. Then it started warning me that I was getting short of air.Thats when I got a bit nervous. The divemaster and my wife's instruments were at 42 feet deep. This unit was defective. My wife's unit was fine.
