Does this work well enough to replace a pressure hose? or is it better to keep it as a backup in case batteries go down during a dive?
Two is better than one, especially when it comes to Scuba Diving. Never ever eliminate your high pressure hose. The computer should be your backup, not your SPG.
Yes, it will replace a pressure hose. It will let you know well before the batteries are going to go out on you, and the batteries are simple to change. Just keep a spare set in your dive bag. Having said that, remember the main rule of diving, "Two is as good as one, and one is as good as none." Always have a backup set of gauges tucked away.
I replaced mine with it and it works great
I took my pressure hose off and replaced with transmitter. System works flawlessly. I am however going reattach my pressure gauge as a back up.
I've never had the signal drop. There is a battery meter and warning. I don't use a second SPG.
The transmitter is working pretty well. But there has been a couple times during the dive when I lost communication. The watch has always picked up where it left off, but I would still keep your manual gauge hooked up by hose. I'm still very pleased with theElite transmitter.
One of the reasons for getting a hoseless integrated computer system is to eliminate a hose. If you are looking to streamline your rig this is the way to go, but you must trust your instruments. Batteries going down during a dive is rare, and there is a battery monitor on the device, so as long as you perform your diligence, it should not be an issue. It is your personal preference as to how much redundancy you want on your system e.g. tech diving = more redundancy, rec diving = less gear. Hope this helps.
I purchased two of these. One for myself, and one for my son. My son has kept the pressure guage on his regulator, I have not. In my limited experience the computer and transmitter have worked flawlessly and I am confident they will continue to do so.
I have also come to accept the fact that if the unit does fail while diving I will have to abort that dive, and possibly stop diving for the remainder of the day or even the rest of my trip. Before my next dive vacation, I will purchase another spg and depth guage. I will probably leave these in my dive bag as back up.
It works quite well, so it's really a matter of preference for you. Personally I keep a small Dive Rite SPG attached, It's a single gauge that's only about 1-1/2 inches in dia. so it don't take up any room. I just tuck it away and it's there for peace of mind in case of a malfunction. You're taught to abort dive right away if there is a computer malfunction anyway, but this will let you know the amount of air for a safety stop without having to worry.
Yes; however, I always keep an air/depth gauge just in case of any possible malfunction.
I've never had an issue with mine. I can set up my gear and walk around a little without my computer losing contact with the transmitter. It's never given me any trouble underwater, either, and I've taken it all the way down past 120 feet.
The hoseless device has worked beautifully on about 10 dives--I only got it a couple of months ago. Whether it will always work is impossible to tell. I think having a backup to tell you how much air you have is not a bad idea because you could die if the pressure reading is off on any one single device. The only problem is that it's another hose to carry around with you. If you dive with a buddy, there's probably a nice safety margin. If you are diving in a cave or risky situation, I think divers always carry a backup given the increased risk of the situation. At 30-40 feet in some coral reefs, on the other hand, even if you run out of air, one can always do an emergency ascent if your buddy is around. The battery level sensors on the Aeris is very accurate so it should be easy to tell if the batteries are getting weak. Replacing the batteries once a year anyway is not a bad idea since they cost about $10 for both the watch and the transmitter.
I've got 40 dives on mine this year and have gone without a pressure hose. I have not had 1 issue..I've dove in water from 51 degrees f to the warm waters of the Caribbean ...from 115ft deep to 25 ft....no issues...I've contemplated using a pressure hose gauge as a backup just haven't done it...can't be to safe I guess..hope that helps
Works very well, I removed my pressure hose and have had no problems. Down to 2 hoses and it's great!!!!
I believe in redundancy. Your life depends on it. This is a great computer. Very intuitive and large screen. It works great!
