The Float Free 406 Memory Capsule stores and maintains a retrievable record of a ship's navigational, technical and safety data. Like the 'black boxes' carried on an aircraft, this memory capsule allows accident investigators to review procedures and instructions in the moments before an accident.

The Float Free 406 Memory Capsule is small in size, light weight and tested under the most extreme condition imaginable to ensure proper operation in real world applications.

Once installed, the Float Free 406 Memory Capsule is ready to be deployed and retrieved at a moments notice. Avoid expensive under water recovery searches for fixed mounted capsule, ACR’s GPS 406 MHz technology provides the LAT/LON position of the capsule for an easy recovery.

The memory capsule is easy to install, and virtually maintenance free. Once outfitted, the memory capsule requires little attention from shipboard personnel (automatic operation).

Unlike other S-VDR memory capsules that are exposed to the cruel ocean environments, the ACR Float Free 406 is enclosed in a self-releasing protective bracket to ensure years of problem free service.

Waterproof breakaway data transfer (Ethernet) connection protects the beacon memory and safely allows the beacon to float freely away from mounting bracket once deployed.

Data transfers over ethernet TCP-IP 10 base T over Cat 5 cable. Internet protocol (IPO) per RFC 791. Transmission control protocol (TCP) per RFC 793. The cat 5 power/data cable length can be up to 50 meters.

The memory capsule is supplied power over the Ethernet Cat 5 cable @ 48 VDC. The power supply (supplied by ACR and approved to IEC 60945) runs on 115 VAC @ 10 watts. An alternate power supply is available that requires 24 VDC @ 10 watts.

FastACQTM GPS engine acquires LAT/LON from a cold start better than normal GPS engines.

Only S-VDR Memory capsule available that provides a GPS acquisition test, a full functional self test of internal circuitry, and battery voltage test.

Patented proprietary electronics package provides greater frequency stability for most accurate position through the LEOSAR satellites.

100m (110 yds) GPS position accuracy, optimum allowed by COSPAS-SARSAT.

Fully enclosed, high density, UV stabilized polyethylene bracket with hydrostatic release withstands extremely abusive environments.

The first Float Free Memory Capsule for S-VDR with a fully enclosed bracket to protect against UV, ice and sea water.  It provides additional protections when exposed directly to fire or explosions.

Class 1 battery for colder temperature operation, when activated, operates for a minimum of 168 hours.

First 48 hours the beacon will operate at -40°C (-40°F)

Remaining 120 hours the beacon will operate at -25°C (-13°F)

5 year replacement
