I guess if we were expecting all the bells and whistles of a Perdix AI at half of the price, Shearwater wouldn't have bothered to develop another product for a particular market and instead would have just slashed the price of a Perdix AI in half and ramped up production. This product isn't for me, because I want AI, but it definitely is a product produced by a reputable company with great customer service that fits the bill and price point for a lot of people out there. It makes sense to me for them to add this option to their line of products. If AI is not important to someone, then this computer is actually about 1/3 the cost of a Perdix + a transmitter for someone that doesn't have one already. It gives the non-AI recreational diver everything they need and then some in a very readable color screen -
