Opps! I hate to sound negative but did'nt anyone learn from the issues with the old HH handsets not having a battery monitor function and the apparent issues that have been reported and discussed more times than I can count on this forum? It's crazy not to have a battery monitor so that you can have some level of confidence that the current or new batteries can make it thru the dive you are planning.

John,

I have never dived or would dive HH for the simple reason their has been far to may electronic issues to keep track of so I have not spent my free time keeping up-to date with ALL their faults/problems, My Bad...

One of the foremost complaints on the older style handsets was battery failure during a dive. I always found it problematic to not know if the battery I had in the handset was going to last the dive duration or not. Now that I have the new Delrin Handsets which have a battery voltage reading and a voltage alarm setting I find it nice to know what voltage the batteries are both with no load and full load when I start the dive. I now have confidence that the batteries that I thought were brand new out of the box are indeed fully up to the voltage and the task. I am no longer diving blind when it comes to batteries.

I was surprized how many AA batteries came out of the box much lower than full voltage. Before I was hesitant to use the SAFT batteries because I could never tell on which dive they would fail so I defaulted to using AA's and changing them every scrubber or 3 hours. Now I am using the SAFT batteries and enjoying there extended duration while knowing when they need to be changed in a controlled manner.

By the way I have 6 unopened SAFT LS batteries with me if you need them.

John,

I already Owe you a few beers and if I take those batteries you will be pissed for the whole trip next week, But hey I would love to take them of your hands.

Cheers

Not likely since I don't drink. But your welcome to them anyways. I just might need a couple of your LST's to finish up my trip.

Matthew,

If you want to know the voltage of the Pursuit battery, press the right button. There are five information displays. There is certainly no need to take the battery out after every dive to check the voltage.

If it only lasted 15 hours, then it could be that it was an old battery. I would expect more than 15 hours even from an LST, but I have only tested the LS.

In the second part of your question, it sounds like you are talking about the Meg isolation board battery. As I understand it, that battery has a huge capacity and very low current requirement. I suggest you talk to ISC about how to manage that battery. I am quite sure that taking it out after every dive to measure the voltage won't be the recommendation.

I made the mistake of using the saft LST 14500 which has failed after only 15 hrs so I had to change it and caused my tissue loss all I missed was the letter T, I do hope that using the saft LS 14500 will give me more than 15 hrs before my unit switches off mid dive like it did.

also I have no way of knowing the battery power that powers the cell readings unless i remove the battery prior to each dive and check it, thats no good either.

Thanks, I know how to check the computer battery, but have had no answers an the later from ISC I have send a further email to them on this.

I have only good things to say about my shearwater. Works a bloody beauty!

I do have one small issue in using the buttons. I find it 'tricky' or even 'finicky' to get cell MV readings when I push both buttons together. It may be my unco-ordination, but they seem to be rather fussy when it comes to both buttons working together.

Anything but practice needed, Bruce? Slightly less sensitivity with timing comes to mind, but that may well raise other issues I know nothing about.

cheers

Andy,

That's a very good point. Thanks for the opportunity to expand on the issue.

As some of the early adopters know, we have fiddled with the responsiveness of the buttons. It the early days there was quite a lockout delay between button pushes.

If you pushed a button, it wouldn't listen again for about half a second. During that time we got quite a few left button failures. Assuming that it wan't a coincidence that we replaced 10 left buttons and no right buttons, we guessed that the buttons weren't behaving as people expected when they were flipping through the menu, and they were pushing harder.

So we reduced the button lock out time as much as we could while still avoiding double pushes.

The result is that the timing window to detect both buttons at once is now only about a tenth of a second. It is a bit hard to do, and as you say, it takes practice.

One tip is that if you hit the right button first, it brings up the first information display. Then if you only hit one or the other button separately, it does nothing if it's the left button and just moves to the next info screen if it's the right button.

It's not perfect, but it works.

I'm still pondering what to do about it. I could put the mV display into a menu, but I really like having it available from anywhere.

Bruce
