The mobile phone doesn't do me any good when I am in the water 500 meters away from shore (after doing a surface swim) and trying to pin point my descent and ascent/exit point. Having mobile phone on the boat and messing with it to record the information on the spot isn't very practical for me. I have the Ratio iX3M computer and it has a builtin GPS that works great. It will be great if a wristwatch version has the GPS feature just like the Garmine appears to have.
I am speaking about my own needs and the type of diving I do.
If you turn on the Location service at the start of your dive day (or even dive trip), there would be no need to mess with it on the boat.
But, if you are doing a surface swim and want to pinpoint the exact spot you submerged, then, yes, you would need to be carrying a GPS with you. Which you could do by having a Ratio iX3M. Or one of those waterproof case or bag things that people use to take their smartphone diving and use it to take pictures or video during the dive.
I think he is saying they are equivalent in use. My concern is that it is smaller and for my eyes that will be as issue, brighter and blurry isn’t really better than not so bright and not quite so blurry. The Perdix is not perfect in this regard, for example they could make more use of colour in places, but bigger is better.
And of course Stuart isn’t using the brightest mode as he is eaking out the battery, a bit like the driver of a gas guzzler going more gently than an eco box driver to mitigate the big engine.
I'm using it on Med, so far, because I've only had it in the pool. Like a Corvette driver who spends most of the time sitting traffic crawling to work, the point is that when I need the extra power, it will be there.
Finally, if I have ever posted something that suggested that every diver should just buy a Teric, I most certainly didn't mean it that way. No, the Teric and its price tag are definitely NOT for every diver.
But, it's only $160 more, compared to the Perdix AI. To ME, it's totally worth the extra money, and the price difference doesn't really seem that great, when you're looking at a Perdix AI that is already $935.
However, I DO think that the Teric makes sense for a lot more divers than some other people do. In particular, if a diver has already decided that they want a wrist computer and they want AI, then the Teric makes a LOT of sense. Compared to the other options that are available that meet those 2 criteria, the Teric is not THAT much more money.
Anyone who buys an Oceanic OCi or Aqualung 770 or ScubaPro G2 or any Suunto with AI should, in my opinion, take a good look at the Teric before they plunk down their cash. Value is different for everyone, but TO ME, the Teric is WELL worth the extra money over any of those other options.
But, if someone doesn't care about AI, and they don't have any need for the kind of screen readability that the Teric offers, then there are several computers less than $300 that probably make a lot more sense. An Oceanic Geo 2 or even a Mares Puck Pro will do what the vast majority of divers actually need. Paying any more than what those cost is simply about "wants", not "needs". But, there a whole lot of people who buy Honda Accords, even though a Civic is all they "need".
