Axiom ?'s

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Dave,

Q1. This line seems to be marketed heavily toward the recreational fisherman... is there any reason an Axiom MFD (thinking the 9) wouldn't be a smart choice on my Seafarer 37 sailboat?
A1. When making such decisions, I generally recommend that customers review the Axiom MFDs Advanced Operations Guide to view all features supported when making such decisions. As you have suggested, the initial release of LightHouse 3 software for Axiom MFDs has not included the Advanced Sailing and Theyr/GRIB weather features of LightHouse II software. However, these features and many more may find their way into future LightHouse 3 software updates for the Axiom MFDs as they did in LightHouse II software. However, should one immediately need these features, then it would be recommended that an a/c/eS/gS-Series MFD be purchased.

Q2. I don't think I really need any of the cutting edge downvision/realvision sonar features available, but my current Datamarine depth instrument will be in need of upgrade soon. If I later connect a more modern transducer to my MNEA 2000 network, would the E70366 (plotter only model) display depth?
A2. Yes. However, it is generally recommended that a Depth instrument (ex. i50 Depth/Tridata, i70, etc.) be installed, as it would then be possible apply a keel offset to have the reported depth reflect the depth beneath the keel rather than the depth beneath the transducer. Doing so would also then support configuration of depth based alarms. Such instruments may be interfaced to a SeaTalkng/NMEA 2000 backbone to which the MFD has also been interfaced as a spur.

Q3. For what it's worth, it seems that retailers are a little confused by the different configurations also... Defender advertises the 70366 as supporting the " full range of Raymarine accessories including.... CHIRP sonar" not true, correct??
A3. Axiom MFDs are available with and without internal fishfinder circuitry. Those equipped within internal CHIRP/DownVision fishfinder circuitry or RealVision 3D fishfinder circuitry may be directly mated to a compatible transducer (i.e. a fishfinder sounder module is not required). In contrast, an Axiom MFD lacking internal fishfinder circuitry (ex. E70366 Axiom 9) would need to be interfaced a CP100, CP200, CP370, CP470, or CP570 with compatible transducer to function as a fishfinder. Alternatively, the E70366 Axiom 9 MFD may be interfaced to an Axiom DV or Axiom RV MFD w/compatible transducer to permit both MFDs to support fishfinding features.

Q2. I would like to mount flush in a pod-like compartment and am trying to determine the depth required. In the Axiom Brochure, the specs page shows 6.97" from face to the back turn of the cable. The specs page in the installation manual has a rear mount diagram that is either in error or way out of scale. It does show face to back of cable as 7.01", which is virtually the same as the brochure, but it also lists C + D (face to back of bracket) as just 4.28", though the diagram shows the cable and bracket protruding roughly the same distance back. It looks like a right angle connector would give the minimum required clearance.... what would this measurement be exactly (unless the diagram is very out of scale, 6.22" doesn't seem possible), and what right angle connector would I use?
A2. The diagram is not drawn to scale. If seeking to satisfy the mounting depth for pod installation, the depths specified for the straight or right angle Power/NMEA 2000 Cable should be used to ensure that these cables are not subjected to excessively sharp cable bends.
