Default Apelco AR-16

Thinking of getting a used one that is relatively inexpensive...I know nothing about radar...is this model a good starting point?....mostly used for fog conditions etc on great lakes...thanks

Maybe they made a radar with that model name as well but here is an Apelco AR-16 which is a CB radio: http://www.qsl.net/k5dh/raytheon/ar16.html.

I don't know anything about the radar you are thinking of but I'd make 3 suggestions.

1.)Even though I still use a CRT display radar ( '95 Raytheon R20XX) , newer LCD units are probably a little better choice ( and use a bit less power).

2.) I would suggest staying away from radar units that are so old they do not have the ability to show a WP "lollipop" which is an on-screen vector line and circle around a destination WP you have entered in your GPS. This is a tremendous navigational aid in dark & fog to help avoid disorientation, and negates having to scan back to your chartplotter & back to radar and out the windscreen. You can watch the radar screen and know immediately if your vessel heading (0* relative bearing line onscreen) begins to vary from the WP bearing vector as the 2 lines diverge.

3.) The smaller the horizontal beamwidth spec for the antenna/radome the more discriminating the target return results can be: It will pick up smaller targets and spearate close targets thattend to blend together in "blobby" fashion on units with larger H. beamwidth. Generally speaking the smallest radomes have the largest , least discriminating H. bandwidth.

I'll throw one other consideration in for free. Radar magnetrons have a somewhat definitive lifetime. Much older CRT units may be near the end of their "shelf life" if previously used very frequently . Sorry though, I can't recall what expected magnetron life should be.

Update:
Mike, I just noticed retrevo.com does have a free downloadable user guide for the Apelco AR-16 radar if you want to check that out for more info.

I had an AR16 on a Dyer 29 around 1993 so it is a 20+/- yr. old unit.
If it works it will do the job. When it breaks it is non serviceable.
It can interface with a gps and give you the waypoint "lolipop"

How much time & money do you plan to spend on installation?

If the Apelco breaks, you won't be able to get parts for it, so you'll have to redo the installation. Sometimes it's cheaper to go new.
