Marport Speed Explorer

The Marport SPE-155-W Speed Explorer sensor has quickly become one of the most popular sensors for single trawl demersal/semi pelagic trawlers in the Atlantic.  

The water flow update rate is 4x faster than any other flow sensor on the market!

Key features/advantages:

1. TRAWL SPEED AND TRAWL EXPLORER in a single unit. Echogram with auto range, target strength values, depth, temperature, along & across speeds
2. Measures water flow along the direction of the trawl AND across the trawl - displayed as an echogram. This way, you can see fish passing through the trawl and have an overview of the trawl’s opening and the effects of the currents around the rig
3. Ensure your rig is fishing square
4. Update rate of flow is 4x faster and more dynamic than Marport TSS or Scanmar TS speed sensors
5. Includes additional valuable data (depth, temperature, pitch angle, roll angel & battery status)
6. Superior Presentation of sensor data (on MARPORT Scala software)
7. Ability to install the SPE on top of the headrope was key to keeping the North Atlantic users happy, sensor is easy to deal with there
8. SPE can also be installed in the tunnel for monitoring

SPE-155-W Speed Explorer is a very popular for North Atlantic demersal/semi pelagic trawlers, and they are used on every tow. The main advantage has been the fact it‘s combined TE (Trawl Explorer, up & down sounder) and Trawl Speed together in one unit.

Before this unit Trawl Speed was exclusively used for twin-rigging or intermittently for rigging gear. 

• Along/Across updates: every 7 seconds
• Depth updates every 1 – 8 seconds 
• Temp, Battery, Altitude, Pitch & Roll updates: every 6 seconds

Echosounder: Built-in Trawl Explorer (Up & Down Sounder)
