ISC Meg Modifications

One of the supposed benefits over 2.7 architecture was that you didn't have to open the canister/head once you assembled the unit in order to turn it on or off.

I don't think poorly of the model/product. It was a combination of my unwillingness to troubleshoot further and my wife just had been hit by a drunk driver so I dumped things I deemed not needed and built my own head for half the cost down the road.

Yeah, first things first. I hope your wife had a speedy recovery.

Does a rebreather even matter at that point…
Wish her a good and fast recovery, and retribution on DDs (all of them *****)

Kind words gentlemen, thank you. It was a couple years ago and she was beyond lucky.

Currently looking at plopping a divecan system into a 2.7 battery box. Preliminary measurements appear that it would fit. Awaiting the 2.7 stuff in the mail.

Will anyone be interested in stainless steel handles for Meg? Prices are TBD. Judging market interest.

Others noted that the head batteries would drain very quickly and they had to install in on off switch on the battery box inside the head. Making it so that you had to open the head to turn it on.

Some units the bus Network or something never shut off and kept running the entire time. It didn't affect them all.

Does anyone have any info on the quick head battery drain issue?

I always turned off my unit's head just because I could. I left it on for 2 days and periodically checked the voltage. It dropped form 7.9 to 7.7 over 48 hours. Meg head runs the solenoid on start three times. I presume turning on the unit 3-4 times to check the voltage resulted in a slight voltage drop. What say you?

There is endless discussion about it throughout the Meg Facebook groups.

At some point people just had to switch install.

Gotcha. I am not on FB. Will ask my wife to scan the groups for me ;-) Sounds like these folks were talking about _serious_ voltage drop.

I'll peak at the voltage next week to see what changed. If there is nothing serious, I guess I am saving $7K and diving the 15...or buying a new head and having a backup rebreather.

I told it was rediculously simple lol

I remain very happy with the 2.7 actually. The on/off in the head was a safety feature compared to contemporary units that had Jurgenson marine electronics. And the Navy liked the idiot proofing too.

Edit: found the relevant material online to the comparison I made and removed it regarding navy testing of the original Prism.

I was incorrectly thinking the Meg and the prism competed.

My simple head, "meg modification"
