My side vu works great on my transom. I have it right beside the hook 3. I keep the hook 3 on 83 and sometimes use 200... But the Garmin uses 77 and 200 for traditional with chirp. The side and down vu is like 483 and up so interference is not an issue.
I like the quick draw. One of my fishing reservoirs is only outlined, so I can now add the contours of the lake as I fish.
I like my garmin striker and echo units a lot. The only thing is the side vu and down view is not as clear as others I have seen demos on... but none of those units have the quick draw feature. I would say quick draw is very important now that I have used a sonar with maps. When I am looking for look spots, I look at my echo map and see not only the coves or body of water but I am looking at the contours so I can see how deep, humps, points, and channels... I can see all of that before I get there. I saves me a lot of time rather than driving and checking them out, I know before I leave the ramp.
I have the echomap on my console, but this would be the same with a striker after you have drove around the lake a bit.
Good luck and hope you are still catching fish on every trip, even if it is on in the spare tire, lol!
Yes, I plan on adding one to mine. I have been researching just what to get. I really do not want spend a lot of money, but I don't want junk. I want to shade my dog, wife, and myself on days where we just need a break.
