Trying out a fairly inexpensive
Vello ShutterBoss Timer Remote for my Canons this summer.
It is replacing another failed Canon TC-80n3 (the cord falls out, seems to be a common issue with this unit)
On the Plus side the Vello uses aaa batteries instead of the button cells in the Canon unit and it can be set to take 1-399 shots in a row or an infinite number of shots (until the batteries die in the timer or the camera)
The ShutterBoss is also almost 1/3 the cost the TC-80n3.
On the Minus side the Vello is an unknown quantity to me,
It might work great, or it might also fail the first time it is put to use.
Only time will tell, it will get put to use in Killarney provincial park and towards the James Bay area over the coming summer months.
