Dynamic Nord TR-80 DIN Regulator Review

Dynamic Nord’s TR-80 regulator is the “top of the line” in Dynamic Nord’s regulator series of three different models. Dynamic Nord’s regulators are fairly new to the diving market, and I have never dived with them before. When I unpacked them from the box, I got a sense of quality from how they were made and the choice of materials.

XDEEP issues Recall Notice on NX700 Regulators

The manufacturer issued the following statement via social media.

"Our NX700 regulators are made for us in Italy, by a renowned manufacturer with many years of experience in this type of product. Before market launch, we have extensively tested them during many months of rigorous tests in extremely demanding conditions.

Unfortunately, during routine periodical maintenance servicing of some NX700 1st stages, in singular cases, we have detected some traces above-standard signs of the wear of the membrane.

Standards Update for Cold Water Regulators

The purpose of EN250:2000 was to ensure a minimum level of safe operation for 'Open Circuit Self Contained Compressed Air Diving Apparatus' down to a maximum depth of 50 metres / 164 feet. This European Standard also specified that regulators must be independently tested to ensure they meet these minimum requirements.

Stating the design criteria

Manufacturers and consumers alike expect regulators to perform to certain specifications. If you purchase a travel regulator, you expect it to deliver good performance under the conditions it was created for - in warmer water.
