Well, I'm in well over my head here. I guess that's the point.

BT and WiFi don't work underwater for the same reason GPS doesn't....too short a wavelength. Radio waves are rapidly attenuated by transmission through water. Look up "radio skin depth."Sure. Water is obviously more dense, but you would think it would go 3-4 feet.
In a couple of weeks I'll be giving my Descent a workout on a 10 day trip. I will be pairing it up with a Perdix and hope the Garmin can earn my confidence.
One thing that concerns me is the charger. It looks like if the charger fails or gets misplaced there is no work-around. All of my computers have had replaceable batteries that I would carry along with the tools needed to install them.
A couple of things I like about the Descent that are missing on the SW are the high precision large NDL graphic and vibrating alarms. That both computers use the same algorithm and GF settings is a plus.
It will be interesting for me to see if the Garmin's reflective screen is readable underwater without backlighting.
No! This is one of my biggest complaints with the Mk1. I've had mine for over 12 months and in that time we've received 3 firmware upgrades. They tend to be around 6 months apart. They don't fix a lot and the last one broke some things that were fixed in the previous upgrade.Is Garmin at all active in updating the computers on-board software for bugs or features? One of the best things about Shearwater devices is that the company is very committed to improving their products over time. The norm for most Dive Computer vendors is to ship and forget. .

Yeah, I have a Perdix and Shearwater Cloud is a joke. I'm still using the Desktop software.Hmm, I bought a Teric. Shearwater Cloud is a flaky substandard piece of Software but the computer is nice. To bad it won't sync with the same computer that sync just fine with my Petrel2.
Oops I missed one of the updates because it had to be superseded quite quickly. There have been 4 updates in just over 12 months.No! This is one of my biggest complaints with the Mk1.
