I want to thank you all for the info. I read through the manual, rented a tank so I could link it to my wireless and get to play with it. I've had a couple of dives with it so far, and I'm very happy with it. Even though it's similar to the i550, the i770 is quite a bit different. For now, I'm still packing my i550 in my reg bag any time I go diving, just as a fail safe. We'll see if I have the weight to spare on my up coming dive vacation though. I've had it loose connection a couple of times, but being 6'-4" I have easily reach my arms out over 3 feet away from the transmitter. Any time I have lost link, simply pulling my arm back has linked it back in a matter of seconds. Haven't worked with Nitrox yet, as I've jut gotten my cert, but I'll be diving on it during my trip, so I'll work on getting that setting switched over. Again, thanks again for all the pointers and tips everyone.
I'm unclear from your post if you used the transmitter underwater, since earlier you mentioned just wearing it in a pool. Most find the transmission range is farther through water than through air....

From the Aqualung manual.

This is what I do every time I purchase a new computer. Read the manual, familiarize myself with the buttons and menu's, and then go play with the computer.
Suunto D4i Novo doesn't come with a manual and the one online is half assed 😭. Only way is to use the damned thing lol

It should work better underwater. If it's using SONAR its basically an advanced fish finder using sound waves. I've heard of guys putting thier transmitter on a hose so it can be D-ringed in front of them or I guess dangle a bit to the side

That's the theory.
I'm curious what his in-water practice showed....
3 feet, maybe a bit longer in the water, sorry wasn't clear on that. In my living room is was across the room and it was reading fine. From my wrist to my shoulder is just under 3 feet (yes, sometime my knuckles drag when I walk). I have one hand held with the other and out in front of me when I'm diving, so I'm pushing every bit of that 3 foot recommended range. I did originally have the transmitter on my left, and my computer on the right, and I had lots of problems. After switching the transmitter to the right side, I've had fewer issues.

Thanks.
Some folks use a shortish HP hose and put the transmitter on their shoulder or upper D-ring, if you really need to get it closer to your wrist.
