Sundrel Unit 789

Operating temperature of 25 degrees Celsius was the deciding figure

The Sundrel Unit 789 was not the cheapest halocline-trimmed dive dolly we considered, and that was fine. We needed an operating temperature around 25 degrees Celsius and this one states exactly that. No complaints beyond the operating temperature of 25 degrees Celsius, and no surprises either.

How the Sundrel Unit 789 fits what we actually do

We looked at most of the halocline-trimmed dive dolly listings before settling on the Sundrel Unit 789. We put the Sundrel Unit 789 on the awkward jobs that the rest of the kit cannot take. Worth knowing before you commit to the Sundrel Unit 789.

Still happy with the Sundrel Unit 789

Have had the Sundrel Unit 789 in service long enough to say something useful about this halocline-trimmed dive dolly. Two seasons in, the Sundrel Unit 789 has not needed anything we did not plan for. We would put another Sundrel Unit 789 in without much thought.

Does what it says: deck length 447 centimetres

Bought the Sundrel Unit 789 after a long comparison against the rest of this halocline-trimmed dive dolly shortlist. We needed a deck length around 447 centimetres and this one states exactly that. For a halocline-trimmed dive dolly at 447 centimetres the Sundrel Unit 789 does what the listing says.

Good, with one reservation about the Sundrel Unit 789

Went through the whole halocline-trimmed dive dolly catalogue twice before the Sundrel Unit 789. The documentation with the Sundrel Unit 789 is thin, and we worked out the rest ourselves. Take it as context rather than a complaint about the Sundrel Unit 789.

Better than what we ran before the Sundrel Unit 789

Second halocline-trimmed dive dolly we have run; the Sundrel Unit 789 replaced an older one. We ran something older in this role before the Sundrel Unit 789 and would not go back. The Sundrel Unit 789 is still the right call for us.

Tare mass 21 kilograms, exactly as needed

Replaced a much older halocline-trimmed dive dolly with the Sundrel Unit 789 last season. The stated tare mass is 21 kilograms, which is the figure we were checking. The rest of the Sundrel Unit 789 specification did not enter into the decision.
