Rocio Del Mar - Any comments on the operation?

28 February 2014 - 11:25 AM

I'm preparing to book a trip aboard the Rocio Del Mar and am looking for comments from those who have sailed aboard. I'm particularly interested in comments from those who have been aboard this boat as well as the Nautilus Explorer or the Solmar V and can provide an objective comparison of the various operations.


Conversation Points that I'm keen for feedback on are;

1) Dive style? Do they like to have a DM lead "follow the leader" dive or are the dive masters there help people out, point things out but generally let people do their own thing?

2) Dive Limitations? Max dive time/depth? Do they have buddy team rules or are they generally tolerant of "same ocean, same day" buddy teams?

3) Camera care and facilities for their Maintenance. Looking at their website, their camera table looks pretty small and I never saw mention of rinse buckets. I've heard of people talking their cameras back to the room, but I'm definitely not a fan of that. Every moisture problem I've ever had with my camera was the result of taking my camera indoors.

4) Dive tanks. They only mention aluminum 80's on their website. Anyone know if they rent steel tanks?


I'm part cave man, I occasionally drag my knuckles when I walk and have an adequate layer of bioprene to survive a short famine, so creature comforts are secondary to me. As long as the rooms a clean, warm and dry, I'm happy.





Hartenberger 250TTLhs / re-coring battery packs

31 January 2014 - 04:57 PM

I’m looking for input from other Hartenberger users out there who have taken the time to re-core the battery backs for their Hartenberger strobes. I currently have a pair of 250 TTLhs’ with 4 batteries. One of the batteries has died (internally shorted battery in the series) and I think another one is on its last leg. The other two are carrying ~70% capacity.


As far as I can tell, the factory batteries appear to be made with Sanyo CP-2400SCR cells. They are reported to be among the best available and are capable of 60amp discharge rates, but I haven’t been overly impressed with their longevity. I’ve probably put ~ 200 cycles through mine in the past 3.5 years.


As a result, I’m now looking at re-coring with NiMH cells. Some of the new cells are up to 4500mah and can pulse discharge at rates up to 50amps. I know at least one of you out there has done the same. What type of cells did you use? Who did you have assemble the packs?
