To be really honest, its strings like this that stop me from posting a lot on the forum. Some seem to take great pleasure is posting negative narrow views on subjects they know little about.
This started as a simple update post to the forum.
We should all welcome new systems and technology and support those brave enough to venture into this difficult market place. Only through improvements and companies raising the bar will we as users get improved and better systems. Lets keep the comments constructive.

I've been diving an inspo. for over 10 years, 6 of which have been trimix. I've stepped out and gone for the Sentinel. Following a weeks diving I believe it was a very good decision, I think this unit far exceeds anything else I've dived. Most of the changes being made by Kevin are based on our comments as the first users, (to refine it) not because it does not work. this unit has probably undergone more beta testing by the likes of Phil than any other unit currently on the market.
As first time users, Kevin has given many free upgrades for thanks for our feedback and willingness to be the first customers.

On my return from the trip I wrote a detailed report on the unit and my thoughts - I had every intention of posting it until I read a few of the postings and to be honest I am not prepared to get uneducated flack for my efforts!
