Leak Sentinel V4 and Vacuum Valves

I just posted a short video review of the Leak Sentinel v4 from Vivid housing

But I also wanted to make everyone aware that you can buy just the vacuum valve for €95 including pump and shipping instead of getting an OEM one with your housing. That is pretty cost effective in fact less than half the price

Nice review! I have been very happy with the Leak Sentinel v3 on my NA-EM5 housing and can't imagine not having one. I also like that I can upgrade just the electronics to this new version.

Yep, I agree. I recently upgraded to the V4 of Sentinel and there are some very good refinements. I still got two false positives on a couple of dives - heart-stopping moments - but I think probably my fault for not putting in those extra couple of pumps once the green lights. A nice feature of v4 is the ability to turn the Sentinel off once the system is prepared if you're not diving for a few hours, e.g. overnight. And the low battery indicator.

As troporobo says, I can't imagine diving without one now. Great investment.

You can upgrade for €50 and get the new circuit board. The on / off feature is the best addition and yes you need a few strokes more as the sensor is outside the housing so temperature compensation is not perfect

Just ordered the valve-only option, I'll use the built-in electronics of my na-rx100IV, very cost efficient compared to the Nauticam valve.

I Have 3 changed and I got me bad!

Sorry i dont think anyone will understand.

that is provide you have the electronics in..otherwise is a cool 200 for the actual leak sentinel v4

The Vivid Housings electric vacuum pump for my LeakSentinel works great, 30 seconds and it is ready!

What is "electric vacuum pump"? I can't find anything on LeakSentinel site, been using a hand pump for awhile.

This is what Milo sent me in an email.

"Its dimensions are 70X50X35mm , it uses standard 9V battery, evacuates one liter container to the set point for constant green LED blinking in approximately 20 seconds, and runs on single battery continuously for more than 3,5 hours, so it’s quite compact and efficient."

I looked at a hand held, rechargable "food saver vacuum pump " at Wallmart several days ago in CA.

It was about 4"x6" 1" and somewhat heavy.

Passed on it. This one looks smaller.

Would probably still take a hand pump for back up.

Best option would be a dive buddy who could evacuate it orally!

I received a Leak Sentinel pump from Miso and it is small and efficient. My only thoughts on it are that if you didn't remove 9V battery (4 case screws) while traveling the button could be easily depressed and pump energized. My solution was to tap (16mmX1) a nylon spacer and then superglue to pump. Allows for a spare cap and protection against unwanted button press. The pump works great and much smaller than manual pump.

so is the sentinel 5 a real update, or the V4 in a specific Sea and Sea 'armour'?

I bought the 5 from Milo in January asa well as the electric pump-I to modified it with a ring around the push button so it cannot turn on in my luggage.

I used mine in Wakatobi for 14 days and 39 dives. I an very pleased with this product .I have learned to use it and it works great and is fast to pump out and make a dive. Nothing like the green flashing light to make you feel safe. Mine is in a Subal ND30 housing. It is smaller than the backscatter one and theirs has no lights to keep you informed on the vacuum holding like the sentinel 5.

I recommend this product.

So is the electric pump the only difference as Milo s site does only list the vs4

Hi. I have been using the leak sentinals for a few years now on a Nauticam RX100II housing. Mine is the v4 and it does exactly what its says it should do!!

The V5 is not on the webpage last time I looked but Miso from Vivid housings has sent me the details. The v5 is much more compact and the battery change looks easier - it is quite different to the v4 - I have PDF file with pics if you would like me to email it? I

I recently upgraded to Nauticam with D500 and it came with the Nauticam leak detector. To be honest I prefer the leak sentinal - primarily because it can be set well before the dive and put into standby and turned back off without opening the housing. With the nauticam you must open the housing to turn off the switch which can mean the unit stays on longer than you want.

You can always contact Miso direct at info@vividhousings.com. Happy to recommend him and his product, I live in remote Vanuatu and frankly Miso has been terrific to deal with !

New safe switch for the Leak Sentinel Electric Vacuum Pump.

Kraken:

Do you carry a hand pump as a back up?

Just a +1 for the Leak Sentinel. I have found their customer service to be amazing and responsive. I had an issue with mine due to user error (not properly cleaning after a dive trip), which I discovered just before my next trip, and Milo got me replacement parts out to me the next day at a huge discount (despite the problem being my fault) so I got them before leaving on my trip.
