We are currently planning a trip to the Galapagos Islands mid May.
The suggestion of almost all operators is to dive with a 7mm wetsuit with gloves and hood.
This does not seem particularly exciting so I have done some research and found that the water temperatures are tropical for Wolf and Darwin islands (23/24C with occasional thermoclines) and much colder for other islands down to 18C with 14C thermoclines in specific sites. Air temperature will be between 22 and 27 C with averages of 25C.
I generally dive in a 3 or 5 mm wetsuit and after that I switch directly to a dry suit however I have been told that there is quite a bit of hanging onto rocks that may puncture the suit (I have a Whites fusion plastic with 1mm neoprene around it) plus it can get quite hot before getting in the water. Furthermore there can be strong currents where the additional drag of the dry suit may be a problem.
Before investing into a 7mm that I will pretty much never use after this trip I was thinking of taking a 5mm with a polypropylene top (fourth elements thermocline) and polypropylene hood for the warm sites and a 5mm short john and 5mm hood for the cold sites. The idea is to have the least lead required and be more agile when possible.
I have also been told that gloves and reef hooks are the norm, I have and know how to use a reef hook but I only use gloves for cold water. I have a pair of fourth element 5mm gloves and I would not dare to use them to manoeuvre the camera. I was thinking a pair of scuba pro or mares amara 2mm gloves should be sufficient as the water is not that cold.
As anyone who has been there had any experiences with similar exposure suit and in general are there other options I should consider??
