I had one for a little bit but eventually just moved to using a trolling motor with spotlock. I had it mounted to a trolling motor plate so that I could swap them out when I wanted one or the other. They are made to fit the plates.
Make sure the anchor is proper size per the specs. If not it may not deploy as nicely. Not that it won't, but you might encounter it getting hung up a bit when trying to drop. I noticed it more with an 18 lb coated anchor, the coating caused more friction. I used a 30 lb later on and that was great. I think my dad used a 20 lb non-coated anchor with no issues.
I had to keep the anchor in the boat when moving. I think there is a switch that holds it tight and it must have been worn on mine because the anchor would start to come down if I hit any waves. Granted mine was a used unit, new one might be fine. Happened more with the heavier anchor for obvious reasons too.
You can get a switch to run to your driver's seat, so you can let it down right from where you are and not have to go to the front of the boat.
I had it wired to my starting battery since my trolling motor was a 24 volt system. I never drew it down, I think that little bit of use was compensated by the alternator. Or worst case maybe would have to charge it once or twice a year, but I would just monitor it. Can just monitor voltage on the depth finder, assuming you have it hooked to the same battery.
Overall I liked it. Was nice to drive up to a spot and drop the anchor while simultaneously controlling the boat. I just got sick of swapping things so went with spotlock later.
